Mobile Computing Disposing of used batteries 103 ❖ A reverse polarity condition should be avoided with all batteries. The main battery is designed so that it cannot be installed in reverse polarity. ❖ Charge the battery only in the computer or in a battery charger designated as an approved option. ❖ When you install the battery pack, you should hear a click when it is seated properly. ❖ Do not expose the battery pack to fire. The battery pack could explode. Maintaining your battery Fully discharging your battery pack will allow better accuracy of the battery meter. To fully discharge your battery pack: ❖ Periodically, disconnect the computer from a power source and operate it on battery power until the battery pack fully discharges. Before doing so, follow the steps below: ❖ If you have extra battery packs, rotate their use. ❖ If you will not be using the system for an extended period, more than one month, remove the battery pack. ❖ Store spare battery packs in a cool dry place out of direct sunlight. Disposing of used batteries The life of a battery pack depends on usage. When the battery pack needs replacing, the main battery light flashes amber shortly after you have fully recharged the battery. You must discard a battery if it becomes damaged. Never attempt to dispose of a battery pack by burning or by throwing it into a fire, and never allow exposure to a heating apparatus (e.g., microwave oven). Heat can cause a battery pack to explode and/or release caustic liquid, both which may possibly cause serious injury. Always dispose of used battery packs in compliance with all applicable laws and regulations. Put insulating tape, such as cellophane tape, on the electrode during transportation to avoid a possible short circuit, fire or electric shock. Failure to do so could possibly result in serious injury.
