[. . . ] Cover the terminals with electrical tape to prevent short-circuits, which could cause the battery pack to ignite or rupture. Use only battery packs recommended by TOSHIBA as replacements. Always make sure the battery pack is installed correctly and securely. Otherwise, a battery pack could fall out and possibly cause injury. Charge the battery pack only in an ambient temperature between 5 and 35 degrees Celsius. Otherwise, the electrolyte solution might leak, battery pack performance might deteriorate and the battery life might be shortened. Be sure to monitor the remaining battery power. If the battery pack and real time clock battery discharge completely, Standby and Suspend will not function and data in memory will be lost. Also, the computer might register an incorrect time and date. In this case, connect the AC adaptor to recharge the batteries. Never install or remove the battery pack without first turning off the power and disconnecting the AC adaptor. Once a battery pack is fully charged, it is recommended that you operate the computer only on battery power until the battery pack completely discharges. Doing so extends battery life and helps ensure accurate monitoring of battery capacity. The Battery indicator may show a rapid decrease in battery operating time when you try to charge a battery under the following conditions: The battery has not been used for a long time. The battery has completely discharged and been left in the computer for a long time. A cool battery is installed in a warm computer. Fully discharge the battery by leaving it in the computer with the power on until the power automatically shuts off. Charge the battery until the Battery indicator glows green. Repeat these steps two or three times until the battery recovers normal capacity. Leaving the AC adaptor connected will shorten battery life. At least once a month, run the computer on battery power until the battery is fully discharged, then recharge the battery.
