Introduction

Lithium Batteries: Types and Features

Since Panasonic became the first company in the world to develop and mass produce lithium batteries for consumer products in 1971, Panasonic has launched a series of lithium batteries in many shapes and sizes including cylindrical types, coin types and pin types. Panasonic has also successfully introduced rechargeable coin-type lithium batteries to the market for applications such as memory back-up or watches. Today, lithium batteries have a proven track record of opening up a host of new fields where conventional batteries cannot be used. Applications range from high-current discharge applications typified by 35 mm cameras to ultra-low current discharge applications in such products as electronic watches or applications such as power supplies for IC memory backup which require long-term reliability. Panasonic has conducted repeated tests on various safety and performance characteristics, in addition to extensive testing on the effects of environmental factors such as temperature. We have accumulated a wealth of corroborative data on the performance of our batteries which cannot be pinpointed by shortterm accelerated tests. As a result, Panasonic batteries have won approval under the UL safety standards in the United States and recognition throughout the world for their high reliability and safety.

Lithium Batteries & General Features

High voltage

The high energy density of lithium batteries and their high voltage of 3V make them ideally suited for use in all kinds of products where the trend is to achieve increasing miniaturization. A single lithium battery can replace two, three or more conventional batteries. The figure on the right shows the number of cells required to provide the C-MOS IC data holding voltage for each type of battery.

Low self-deterioration rate and superior storability

Since lithium batteries employ substances for the cathode active material (such as poly-carbonmonofluoride for the BR series and manganese dioxide for the CR series) that are chemically very stable, storage life is more than five times that of conventional batteries, with more than 90% residual capacity after 10 years of storage.

Lithium Batteries & General Features (Cont.)

Outstanding electrolyte leakage resistance

Lithium batteries employ organic electrolytes with minimum creeping so they are vastly superior in terms of leakage resistance under environmental changes compared to other types of batteries that employ aqueous solution electrolytes. The batteries achieve stable characteristics under high temperature and humidity conditions (45°C, 90% RH, 60°C, 90% RH), and even under heat shock which constitutes the severest challenge for batteries.

Wide operating temperature range

Due to the use of organic electrolytes with a solidifying point that is much lower than the aqueous solution electrolytes used in other types of batteries, lithium batteries are capable of operation in a wide range of temperatures. Not only do the high operating temperature BR series cells use a special engineering plastic as the material for the gasket and separator instead of the conventional polyolefin resin, but their operating temperature range has also been significantly increased by employing an electrolyte with a high boiling point.

Model Numbers

How to interpret the model numbers generally used for coin-type lithium batteries

The model numbers are normally written using two upper-case English letters and a figure consisting of three or more digits as shown in the example below. Example B R 2 3 2 5 Battery type Round Diameter Height Figures to first decimal place with decimal point omitted(ex.2.5mm)

Integers omitting fractions(ex.23mm Dia.) In accordance with JIS and IEC standards

The above numbering system is supported by the Japan International Standard Committee of Clocks and Watches and is also an established practice in Japan.

Selecting a Battery

Selecting batteries

The steps for selecting batteries for the power supplies of specific equipment are summarized below. Preparation of required specifications (draft) The required specifications (draft) are studied by checking the requirements for the batteries to be used as the power supplies of the specific equipment and their conditions against the battery selection standards. The technical requirements for battery selection are shown in the table below for reference purposes. Selection of a battery Select several candidate batteries by referring to the catalogs and data sheets of batteries which are currently manufactured and marketed. From this short list, select the battery which will best meet the ideal level of the requirements. In actual practice, however, the "perfect" battery is seldom found by this method. Instead, the basic procedure followed should be to examine the possibility of finding a compromise or partial compromise with the required specifications (draft) and then make a selection under the revised requirements from the batteries currently manufactured and marketed. Such a procedure enables batteries to be selected more economically. Questions and queries arising at this stage should be directed to our battery engineers. Sometimes, although it may not be shown in the catalog, an appropriate battery may have become available through recent developments or improvements. As a rule, the required specifications are finalized at this stage. Requests for developing or improving batteries If the battery that meets the essential and specific requirements cannot be found through the selection process described above, a request for battery development or improvement should be made to our technical department. A request like this should be coordinated as early as possible to allow for a sufficient study period. While this period depends on the nature of the request and the difficulties involved, a lead time of at least 6 to 12 months is usually required.

Safety Precautions for Using, Handling and Designing

Common to Both Primary and Rechargeable Batteries

Classification

Item Voltage measurement Internal resistance measurement Electrical characteristics check Cleaning Washing and drying

Precaution

To measure the battery voltage, use an instrument with an input resistance of 10 M or higher. To measure the internal resistance, use a 1000 Hz AC instrument. Even minimal shorting causes the battery voltage to drop, requiring a period of time for the voltage to recover. Checking the voltage characteristics before the voltage has sufficiently recovered in such a situation may result in a misjudgment of battery voltage. Prior to installation in the equipment, wipe the batteries and equipment terminals clean using a dry cloth, etc. - Washing: Use of a conductive detergent causes batteries to discharge, the battery voltage to drop and the battery performance to deteriorate in other ways. Be sure to use a non-conductive detergent. - Drying: The heat produced when the temperature of the battery units rises above 85 C deforms the gaskets and causes electrolyte leakage and a deterioration in performance. Be sure to dry batteries only for short periods of time at temperatures below 85 C. - Ensure that dust and other foreign substance will not cause shorting between the poles. - When handling batteries, wear finger covers or gloves made of rubber, cotton, etc. to protect the batteries from dirt. Strictly comply with the conditions outlined on the next page. Give sufficient consideration to safety in design when a multiple number of batteries are to be used. Consult with Panasonic concerning packs of multiple batteries. When other types of batteries are also to be used in the same equipment, design the circuitry in such a way that the current (leakage current) from the other batteries will not flow to the lithium batteries. (This applies to primary batteries.) This requires special circuitry:Please consult with Panasonic. Do not use lithium batteries together with different types of batteries in series or in parallel. (This applies to rechargeable batteries.) Take precautions in design since the internal resistance increases when batteries approach the end of their service life. - Ensure that the batteries can be replaced easily and that they will not fall out of position. - Give consideration to the battery dimensions, tolerances, etc. - Give consideration to the shape of (+) and (-) electrodes of the batteries and their tolerances to prevent installation in reverse. - Clearly indicate on the battery compartment the type of batteries to be used and their correct installation direction (polarities). - Limit the electrical circuits inside the battery compartment only to the circuits relating to the battery contacts. - With the exception of the terminal areas, insulate the battery compartment from the electrical circuits. - Take steps to minimize any damage to the equipment resulting from electrolyte leakage from the battery compartment. - Take steps to ensure the batteries are not located heat generating components in the equipment. Installing batteries near a heat source will heat up the batteries, causing thermal deformation of the gasket and resulting in electrolyte leakage and a deterioration in performance.

Contacts and Connection Terminals

Contact point materials Contact pressure of contacts Shape of terminals Connection terminals

Use nickel-plated iron or nickel-plated stainless steel for the contact points. In order to ensure stable contact, use the following levels of contact as a general guideline: 5N to 15N for cylindrical types 2N to 10N for coin types

Use of Y-shaped terminals (2-point contact) for both the (+) and (-) electrodes yield stable contact.

If lead wires and connection terminals such as tab terminals are required for the batteries, consult with Panasonic since we offer a range of external terminals (connectors, etc.).

Notes

(1) Shorting causes the battery voltage to drop to about 0V BR-2/3A voltage recovery after short-circuited (example) before slowly recovering from the shorted state. It takes 3.5 Temp : 20°C time for the initial voltage to be restored. Notice that measuring the open-circuit voltage immediately after 3.0 Shorting time 3~5 sec. shorting may lead to a misjudgment that the battery is 10 sec. 20 sec. abnormal. The figure on the right illustrates how voltage 2.5 (V) recovers after shorting. 3.0 (2) Reverse current preventing diodes: Since lithium 2.0 2.5 primary batteries are not rechargeable, use of a reverse 2.0 current preventing diode and a protective resistor in 1.5 1.5 series is required where there is the possibility of ~ charging in the equipment circuit. Use a silicon diode or 0 30 60 90 120 (sec) Schottky diode with a low reverse current as the reverse Recovery time(h) 1.0 current preventing diode. To maintain the characteristics of a coin-type lithium battery, the total ~ charging amount of the battery during its total usage 0 1 4 5 2 3 Recovery time(h) period must be kept within 3% of the nominal capacity of the battery.

Primary Batteries

Since lithium primary batteries are not rechargeable, use a reverse current blocking diode and a protective resistor in series where there is the possibility of charging in the equipment circuit.

Reverse current blocking diode

· Diode used: Use a silicon diode or Schottky diode having only a low reverse current (this current varies with temperature). · Selection standard (in order to maintain the battery characteristics): The total allowable charging amount of a battery during its total usage period must be no greater than 3% of the nominal capacity of the battery for a coin-type battery or 1% for a cylindrical battery. [Example]: When a CR2477 (1000mAh) coin-type battery is to be used for 5 years, a reverse current blocking diode with a reverse current of 0.7µ A or less is required. <Calculation method> 1000mAh (CR2477) x 3% (coin-type battery) = 30mAh 30mAh ÷ usage period (5 years x 365 days x 24 hours) = 0.7µA

Design for Memory Back-up Use

Selecting batteries

When selecting batteries, give consideration to such factors as the current consumption of the equipment in which the batteries are to be used, the expected life of the batteries, and temperature in the operating environment. At low operating environment temperatures, the consumption current of the ICs drops but the discharge voltage of the batteries will also decrease. Also it is important to note that the capacity deterioration of batteries in long-term use becomes significant at high operating temperatures.

Memory backup circuit and holding voltage

The circuit typically used for memory backup is shown in the figure on the right. The memory holding voltage is expressed as: VB - VF - IF x R >memory holding voltage of IC.

+ 5V

IR VF IC R VB B IF

Reverse current blocking diode

Since lithium primary batteries are not rechargeable, use of a reverse current blocking diode and a protective resistor in series is required where there is the possibility of charging in the equipment circuit. Use a silicon diode or Schottky diode with a low reverse current as the reverse current blocking diode. To maintain the characteristics of a coin-type lithium battery, the total charging amount of the battery during its total usage period must be kept within 3% of the nominal capacity of the battery. For example, assuming that a CR2477 (1000mAh) will be used in a memory backup power supply for 5 years, charging by the reverse current of the reverse current blocking diode should be no greater than 30mAh (=3% of 1000mAh), thus: 30mAh ÷ usage period (5 years x 365 days x 24 hours) = 0.7µA In other words, a reverse current blocking diode whose reverse current is not greater than 0.7µA must be selected. Allowable total charging amount : Within 3% for coin-type batteries Within 1% for cylindrical type batteries

Note that the reverse current of reverse current blocking diodes varies with temperature.

Batteries with Terminals

Highly Reliable Terminal Welding

(1) Using a laser to weld terminals

Panasonic uses a laser welding method to weld the terminals onto the batteries so they can be mounted onto PC boards by soldering. This method has the effect of boosting the tensile strength accompanying a welding strength to approximately 1000 N (approx.10Kgf) compared with 20N to 50N (approx. 2 to 5 kgf) yielded by conventional resistance welding. Laser welding also, more or less, cuts in half the individual variations occurring in the welding. Furthermore, it enables terminals to be welded onto thin batteries, such as those with a thickness of 1.6 mm, and it improves compatibility with many other uses. This highly reliable terminal soldering method can be used in a wide range of applications, eliminating the need for reinforcement or other such means.

(2) Pre-soldering

The tips of the terminals are pre-soldered in order to enhance the reliability of the soldering.

Pre-soldering

Pre-soldering

Complete Line-up

Panasonic offers a full range of batteries with terminals for PCB mounting. Since the terminals come in a variety of types, please contact Panasonic for further details. A more limited selection of simple battery holders to support the batteries is also available.

Soldering

(1) Using a soldering iron

Do not allow the soldering iron to make direct contact with the bodies of the batteries. Complete the soldering within 5 seconds while maintaining an iron tip temperature of about 350°C, and do not allow the temperature of the battery bodies to exceed 85°C.

Precautions

Do not attempt to weld terminals to the batteries*

Example where the terminals were soldered straight onto a coin-type lithium battery, the terminals were connected to a PC board or other electronic components, and the heat generated by the soldering adversely affected the battery, resulting in a deterioration of the battery characteristics: The heat generated when terminals are mounted using solder causes lithium to melt. The separator melts and becomes perforated. The positive and negative poles are welded together, causing "internal shorting." In terms of the battery characteristics, the open-circuit voltage and electrical capacity are both reduced. The battery loses its function or it bursts some in rare cases.

(2) Automatic dip-soldering bath

Soldering with a dip-soldering bath can be used but do not allow the temperature of the battery bodies to exceed 85°C. It is important to note, depending on the temperature conditions inside the dipping device,that the battery body temperature may rise after dipping due to the residual heat retained. When a post-dipping temperature rise is observed, review the temperature conditions and consider a dipping time reduction or a way of forcibly cooling the batteries after dipping.

Basic conditions Dip-soldering bath temperature Dipping time Number of dips 260°C or less Within 5 sec. Not more than 2

Soldering

Terminal

Solder Welding Cathode cap Lithium(note 1) Separator(note 2) Cathode

* Consult Panasonic if the battery body temperature will exceed 85°C.

Never Use Reflow Soldering

Never use reflow soldering since doing so directly heats the battery surface to high temperatures, causing electrolyte leakage, deterioration of battery characteristics and risking bursting or ignition.

(note 1) Metal whose melting point is about 180°C (note 2) Non woven cloth of polypropylene whose melting point is about 165°C *Terminals shold only be welded to the batteries by qualified personnel with the proper equipment.

Rechargeable Lithium Coin Batteries: Overview

Panasonic offers a wide range of rechargeable lithium coin battery chemistries to meet a variety of application requirements and voltage levels. These component sized batteries provide a highly reliable and durable power source for applications that use low voltage ICs and require space saving designs.

Features · Excellent overdischarge (0V) and overcharge withstand · · ·

capabilities Wide operating temperature range (-20 to +60 C) Low self discharge rate (approximately 2% per year) Environmentally friendly chemistries

Applications · Memory back-up in RTC circuits for products such as: · Notebook and desktop computers · Mobile phones, handheld devices and PDAs · Office equipment (fax machines and appliances) · Main power for watches (MT series)

Selecting the right chemistry for your application

VL Series: Ideal for applications where voltage stability is more important than capacity. ML Series: When capacity is needed more than voltage (longer back-up times). NBL Series: Maintains a higher capacity at lower voltages than the VL or ML. MT Series: Ideal for use as the main power supply for rechargeable watches and other applications.

Vanadium Pentoxide Lithium Rechargeable Batteries (VL series) Charging

Charging circuits

Charging/discharging cycle Approx. 1,000 times at 10% discharge depth to nominal capacity Charging system* Operating temperature Constant-voltage charging. (Please strictly adhere to the specified charge voltage) -20°C ~ +60°C

* Consult with Panasonic concerning constant-current charging systems. The charging circuit is crucial in terms of ensuring that full justice will be done to the battery characteristics. Consider it carefully as the wrong charging circuit can cause trouble.

Precautions regarding the charge voltage setting

Under no circumstances should trickle charging, which is used for nickel-cadmium batteries, be used. Ignoring this precaution will cause the battery voltage to rise to about 5V, resulting in a deterioration of performance.

3.4V 5V 3.6V

VL 0V 0V

VL

Incorrect

Correct

Charge voltage range

If a fixed-charging method is applied, please adhere to the specified charging voltage. The guaranteed value over an operating temperature range from -20 to +60°C is 3.4V±0.15V. (Actual value: 3.4V±0.20V) * If the charging voltage exceeds the specifications, the internal resistance of the battery will rise and may cause battery deterioration. Also, with a charge voltage around 4V, corrosion of the (+) terminal (case) may occur, causing leakage. ("Influence of charge voltage" page 69.) * It is not possible for the battery capacity to recover completely when the charging voltage is below the specification.

Recommended charging circuits

Basic conditions Charge voltage: 3.4V±0.15V Charge current: For a battery voltage of 3V VL621 Approx. 0.2 mA or below VL1216, VL1220 Approx. 0.5 mA or below VL2020 Approx. 1.5 mA or below VL2320, VL2330 Approx. 2.0 mA or below VL3032 Approx. 4.0 mA or below (It is permissible for the current to increase beyond the above level when the battery voltage drops below 3V.)

Mixed usage of batteries

Do not use these batteries and lithium primary batteries or other rechargeable batteries together, and do not use new batteries and old batteries together even if they are of the same type.

Manganese Lithium Rechargeable Batteries (ML series) Charging

Charging circuits

Charging/discharging cycle Approx. 1,000 times at 10% discharge depth to nominal capacity Charging system* Operating temperature Constant-voltage charging. (Please strictly adhere to the specified charge voltage) -20°C ~ +60°C

* Consult with Panasonic concerning constant-current charging systems. The charging circuit is crucial in terms of ensuring that full justice will be done to the battery characteristics. Consider it carefully as the wrong charging circuit can cause trouble.

Precautions regarding the charge voltage setting

Under no circumstances should trickle charging, which is used for nickel-cadmium batteries, be used. Ignoring this precaution will cause the battery voltage to rise to about 5V, resulting in a deterioration of performance.

3.1V 5V 3.3V

Incorrect

Correct

Charge voltage range

If a fixed-charging method is applied, please adhere to the specified charging voltage. Guaranteed voltage is 2.8V ~ 3.2V at the temperature of -20°C~60°C. * If the charging voltage exceeds the specifications, the internal resistance of the battery will rise and may cause battery deterioration. Also, with a charge voltage around 4V, corrosion of the (+)terminal (case) may occur, causing leakage . ("Influence of the charge voltage" on the back.) * It is not possible for the battery capacity to recover completely when the charging voltage is below the specification.

Recommended charging circuits

Basic conditions Fixed-voltage charge Charge voltage: 2.8~3.2V (Standard voltage: 3.1V) Charge current: For a battery voltage of 2.5V ML612S,ML614S,ML616S Approx. 0.3 mA or below ML621S Approx. 0.6 mA or below ML920S Approx. 1.2 mA or below ML1220 Approx. 1.2 mA or below ML2020 Approx. 3.0 mA or below

Mixed usage of batteries

Do not use these batteries and lithium primary batteries or other rechargeable batteries together, and do not use new batteries and old batteries together even if they are of the same type.

QS9000 / ISO9001 Approval

The Lithium & Micro Battery Division has acquired certification under ISO9001, the international standard for quality assurance, for its cylindrical type lithium batteries and coin-type lithium batteries. In addition, we have acquired certification under QS-9000, the quality standard for the automobile manufacturing industry, for its coin-type lithium primary batteries.

QS-9000

The QS-9000 standard was established by the "Big Three" U.S. automakers (Daimler-Chrysler, Ford and GM) on the basis of the ISO9001 international standard governing quality assurance but with additional requirements of their own. A company which has been certified under this standard can supply highly reliable products by incorporating into its quality system proven "predictive management" techniques which are substantiated by numerical data from a customer satisfaction survey, failure mode and effects analysis (FMEA), process capability analysis, measurement systems analysis, etc. which are required under the standard.

The United States Department of Transportation (DOT) regulates the transportation of all lithium cells and batteries in commerce. All Panasonic lithium batteries are not subject to the requirements of the DOT Subchapter C Hazardous Material Regulations because each of our batteries meet the requirements of 49 CFR 173.185(b). The only exception to this our BR-C battery which contains 1.7 grams of lithium per cell and is not subject to the Hazardous Material Regulations because it meets the requirements of 173.185(c). All Panasonic lithium batteries are exempt from the DOT Hazardous Materials Subchapter as long as they are separated to prevent short circuits and packed in strong packing for conditions normally encountered in transportation.

5-2

International Civil Aviation Organization (ICAO)

All Panasonic lithium batteries are considered non-dangerous by the International Civil Aviation Organization (ICAO) because they meet all the requirements of Special Provision"A45". The batteries must be shipped in strong packaging and packaged in a manner that prevents them from short-circuiting.

5-3

International Air Transport Association (IATA)

All Panasonic lithium batteries are considered non-dangerous by the International Air Transport Association (IATA) because they meet all the requirements of Special Provision"A45". The batteries must be shipped in strong packaging and packaged in a manner that prevents them from short-circuiting. If you build these cells into a battery pack, you must also assure that they continue to remain unregulated (i.e.-meet the requirements of 49 CFR 173.185(b) or (c)) or you must ship them in compliance with applicable regulations. For further information on the transportation of Panasonic lithium batteries, please contact your local Panasonic Battery Sales Group office.

Security Export Control

All Panasonic Lithium batteries are unregulated by the US Commerce Control Regulations because no single battery exceeds 27cc in volume (approximately the volume of a size "C" battery). If you plan to assemble any of the Lithium batteries into a pack that would have a volume greater than 27cc, your pack may be subject to export control. For additional information please contact your local Panasonic Battery Sales Group office.

Avoiding Hazards

Case Study and Explanation

To store batteries, place each of the batteries in the sections provided on the designated tray in such a way that they will not make contact with one another.

Ignition

2,000 new batteries were thrown randomly into a cardboard box where they were stacked on top of one another. About 30 minutes later, smoke was seen emanating from the batteries followed by ignition several minutes after that. Hazard Example: Ignition of batteries stacked together

Generating Heat

21 cylindrical type lithium batteries with tab terminals were placed in a 20 piece tray--one battery more than the capacity of the 20-piece tray shown in the figure--two of the batteries were placed together with their poles reversed. As a result, the tab terminals came into contact with each other, causing external shorting, and the temperature of the two batteries rose dramatically, generating heat and causing the halon shrink tubes to burst. Since two batteries were placed in a space (indicated by ) allocated to one battery, their terminals made contact with each other, and external shorting resulted.

Rupture

This particular case involves batteries which were packed in trays and destined for OEMs. The batteries were packed in an intermediate package consisting of 10 trays with each tray containing 20 batteries, and the trays were stacked on top of each other. The intermediate package (of the 10 trays) was opened at the distribution center and five of the trays were delivered to one customer. Since the trays were stored at an angle inside the box, the batteries fell out of the trays and became stacked on the bottom inside the small box. As a result, some of the batteries burst. Hazard Example: Bursting of batteries stacked on top of one another

Preventing Quality Problems

Reduction of Battery Voltage and Deterioration of Capacity

(1) Reduction of battery voltage and deterioration of capacity through contact with antistatic conductive materials

Incidents have been reported where terminal-mounted batteries for memory backup or coin-type lithium batteries have come into contact with antistatic conductive materials, thus forming external discharge circuits and leading to voltage drops or capacity deterioration. In manufacturing plants using ICs, LSI and other semiconductor components, thoroughgoing antistatic measures are taken. Various protective materials are used to prevent static: most of them have special compounds of carbon, aluminum foil and other metals and are therefore conductive. These protective materials are used, for example, in the form of packaging bags, trays, mats, sheets, films, corrugated boards and resin cases. A protective material may have a resistance ranging from 103 to 106 /cm, for instance. This means that if the (+) and (-) terminals of a battery come into contact with this material, a current ranging from several milliamperes to several microamperes will flow and the battery will discharge, causing voltage drop and capacity deterioration.

A terminal-mounted battery was inserted into a conductive mat. The battery charge was exhausted in several days. +

A battery was placed directly on a rubber sheet spread over a worktable. The (+) and (-) terminals were in contact with the sheet and the battery charge was exhausted.

Battery-mounted PC boards were inadvertently brought into contact with spacers and a conductive rubber sheet. The battery Spacer charge was exhausted.

When batteries are to be used near protective materials, take every possible care to ensure that the (+) and (-) terminals of the batteries or PC boards, etc. on which batteries are mounted do not touch these protective materials directly.

Preventing Quality Problems

(2) Reduction of battery voltage and deterioration of capacity through contact between batteries

Incidents have been reported where terminal-mounted batteries for memory backup or coin-type lithium batteries have come into contact each other, thus forming discharge circuits (shorted state) and leading to voltage drops or capacity deterioration. Observe the following precautions. 1. Remove the batteries from the tray one at a time. If the tray is turned upside down, the batteries will come into contact with each other, forming discharge circuits. 2. Do not place batteries randomly in a parts box or other container. Discharge circuits will be formed by multiple batteries coming into contact, causing the batteries to discharge and drain.

Recommended procedures

*Utilize the tray lid in taking out batteries

Prohibited procedures

*Do not throw batteries randomly into a parts box by turning over trays containing batteries.

*Contact of batteries with each other forms discharge circuits, thus the batteries are drained.

*Lay a tray lid flat and place a tray containing batteries on top of it: batteries are pushed up by protrusions of the lid tray so that they can be easily picked up with fingers.

Memory Erasure Problems

Coin-type lithium batteries are often used as the power supplies for memory backup in various equipment. However problems with the erasure of valuable data in the memory due to improper contact between the batteries and equipment can occur.

Fig. 1: soldering

1. When batteries are to be used continuously for a prolonged period Select tab terminal-mounted batteries, and solder the tabs to the battery connection terminals of the equipment. (See Fig. 1) When batteries need to be replaced, use a battery holder (see Fig. 2) or battery with lead wire connectors (see Fig. 3). Battery holders made by Panasonic (exclusively for the CR2032 and BR2032, see Fig. 2) are available for use. 2. When batteries need to be replaced in the short term, select batteries with no terminals or lead wire connectors. Use of Y-shaped terminals (2-point contact) for both the (+) and (-) poles as the shape of the connection terminals in the equipment helps to achieve a more stable contact. (See Fig. 4) The contact pressure of the contacts should be no less than 2 to 10N (approx. 200 to 1000 gf). (See Fig. 5) To prevent momentary contact failure of several milliseconds in the circuit, the use of a tantalum capacitor, etc. with a capacitance of several microfarads is effective. (See Fig. 6) For the connection terminals of the equipment, use iron or stainless steel with nickel plating at the very least. Gold-plating is more suitable when the contact resistance must be reduced. Note: Do not touch batteries with bare hands because perspiration (salt), body oil etc. will increase the surface resistance which may lead to defective contact.
