1. AlkalineMAX Version 4.0 Upgrade Enhancements for LCD881 & LCD882 Chargers:

· · · · · Improve recharged capacity for all battery types with Nickel Metal Hydride (NiMH) increased up to 2200mAh in AA sized. (See attachment for further charging notes). Better battery detection and improve recharged performance for all battery types. Supports of the new Titanium battery. Charge time is now varied between 1 ­ 17Hrs depending on the type, capacity and battery condition.

2. Installation of the Upgrade Chip:

Fig. 1: Step1 : Before you start, make sure you have the followings: · 1 x flat head screw driver (A small size will do.). · 1 x Philip-head screw driver · Super glue remover (For ReZAP LCD882 only!) · The upgrade chip (of course!). · Fig. 2: Step 2: · Turn the power off and disconnect the power cable , then turn the charger up side down as shown in Fig. 2. · Apply superglue remover to each of the rubber feet and wait a few minutes for easy removal. (Applicable to the ReZAP LCD882 only as the glue used is quite strong!) · Use the flat-head screwdriver to remove the four rubber feets to reveal the hidden screws. Step 3: · Use the Philip-head screwdriver to remove the five screws as shown in Fig. 3.

Step 4: · Remove the base cover to reveal the internal circuit of the charger as shown in Fig. 4.


Fig. 5:

Step 5: · With the base cover open, turn the charger right side up as shown in Fig. 5. · Use the flat-head screwdriver to push down on the positive terminal plates one by one as shown on opposite. · When all the positive terminal plates are pushed down, they should show the gaps as shown in Fig. 6. This ensures easy sliding out / removal of the circuit board at the base of the charger.


Fig. 6: Step 7: · Turn the charger up in the standing position as shown in Fig. 7. · Slide the main circuit board out and use the flat-head screwdriver to remove the existing microprocessor as shown.


Fig. 7: Step 8: · Place the new upgrade chip with the end that has a notch (PIN 1) pointing towards the chip socket as shown in Fig 8. · Dismount one end of each of the four springs from the negative metal plates to make it more accessible to the chip socket as shown and slide the circuit board further out if necessary.


Fig. 8:


Step 9: · Position the new chip over the chip socket, firmly and carefully pressing the chip down slowly so all of the pins of the chip are inserted into the chip socket properly as shown in Fig. 9. Fig. 9: Step 10: · Reassemble the circuit board; reconnect the springs and ensure the earth wires do not get jammed when the base cover is remounted as shown in Fig.10. All negative metal plates in the four battery slots should move freely when all earth wires are cleared. Adjust if necessary.


Fig. 10: Step 11: · Plug in the cable and turn the power on to test the charger. If the green lights do not flash when batteries are inserted then turn off the power, unplug the cable and go back to STEP 4 to reinstall the upgrade chip correctly (Check to ensure you got the chip's PIN 1 in the right way and all of the pins are inserted properly). Should the green LEDs function correctly, then your installation is successful and you should continue to reassemble the rest of the screws, rubber feets and affix the small AlkalineMAX v4.0 label provided on the base plate of the charger as indication of upgrade done. · Congratulation! You have successfully done the upgrade by yourself. Now enjoy great recharging.

Important Charging Notes for the Upgraded Charger/RBC883:

· · Charge only Alkaline, Titanium, RAM (Rechargeable Alkaline Manganese), NiCd and NiMH batteries. DO NOT charge Carbon Zinc (such as heavy duty and general purpose types) or Lithium batteries in this charger. Charge alkaline cells before they go completely flat. If the cells are discharged beyond the point of return (less than 0.9V), chances are that they will not be revived properly. Most electronic devices cut off at the 0.9 volt level; however devices such as torches, radios, clocks or the like do have the tendency to drain the batteries completely. For best result, charged alkaline cells should be removed from the charger within 24 hours after charging finished. Continuous connection to the metal plates (whether the charger is ON or OFF) in prolong period will shorten battery life. Alkaline cells should be disposed of promptly when they have been rejected by the charger (green light turns off) or won't fully charged anymore or don't power the device for long. Different branding of alkaline cells generally means different cell qualities and hence the recharged results. Do not be surprise to find out that some top branding alkaline cells may only yield relatively fewer cycle lives than others not so well known brands. The idea is to try using a variety of brands of batteries and decide for yourself the brands that work best in your applications and in the ReZAP charger. For best results, ReZAP batteries are recommended as they have been designed to work best in the ReZAP charger. Cycle life is based on battery receiving regular maintenance and is also depends on the depth of discharge. In general, shallow discharges provide more cycles than deep discharges. The charger has four main slo ts with four corresponding green lights. Only put one battery per slot. Do not try to put one battery on top of another in a single slot. Please do not connect the 6V cable clips to any other types of batteries except 6V lantern batteries as recommended. Do not return fully charged batteries to the charger for an extra boost. This action will significantly reduce cycle life. After batteries are charged, test them individually in the battery tester slot first before use. Only use batteries that show the same voltage strength together. For alkaline batteries, use those that show 4 Green lights and for rechargeable batteries, use those that show 3 Green lights together. The 9V and 6V batteries occupy the first and forth slots respectively. When a 9V or a 6V battery is being charged, do not place another battery in the first (far left) or the forth (far right) slot as they may conflict with one another. When charging 9V or 6V battery, leave battery in charger for an additional 2-3 hours after the green light appears. 9V and 6V-lantern alkaline batteries are not charged using "individual cell" technique due to their internal structure (multiple cells linked together in series to give a higher battery voltage). As such any fault or weakness amongst the cells can result in the battery being poorly recharged or not useable at times. Do not expect too highly of the recharged results for these batteries.

Turn the power off and remove the plug before cleaning of the charger. · The Plastic Body can be cleaned with a damp cloth and then wiped dry with a soft cloth. Do not use any abrasive or solvents on any plastic surface. · The battery compartment contacts can be cleaned using a piece of cloth dampened with Methylated Spirits solvent (available from most hardware stores). Alternatively a clean pencil eraser can be utilised to rub off any dirt and or deposit that might adhere to them.


The charger has a built-in battery tester, which measures voltage level of batteries, one at a time and displays this strength using the 4 green lights. When a battery to be tested is placed into the tester slot with the rest of the other slots being empty, the voltage level of the battery is displayed for about five seconds and if the battery is not removed from the tester slot, automatic charging will proceed. In tester mode, the 4 x Green lights move horizontally from left to right illustrating the followings: · · · · · No Green light - battery is dead or voltage is extremely low. 1 x Green light - Very Low strength voltage, 2 x Green lights - Low strength voltage, 3 x Green lights - Medium strength voltage, 4 x Green lights - High strength voltage.


· · T ?he tester shows only maximum 3 Green lights for rechargeable batteries when "full" as their voltage rating is 1.2V instead of 1.5V like that of alkaline batteries. Some exhausted and or faulty batteries show a false voltage up to 1.5V or higher when measured by means of a volt meter or the built-in tester, but when you put them to use, they quick die out. These batteries should be disposed off straight away to avoid eventual battery leakage.
