Short-circuiting the battery can cause it to overheat and may cause damage to the battery or the computer. ❖ Do not incinerate a spent battery, as this could cause it to explode and release caustic liquid. ❖ If a battery is leaking or damaged, replace it immediately. Use protective gloves when handling a damaged battery. ❖ To replace the main battery, use an identical battery that you can purchase through the Toshiba Web site at accessories.toshiba.com. ❖ 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.
