Taking care of your battery
The following sections offer tips on how to take care of your battery
and prolong its life.
Safety precautions
❖ If the battery pack produces an odor, overheats or changes
color or shape while it is being used or charged, turn off the
computer’s power immediately and disconnect the power
cord/cable from the power socket. Carefully remove the battery
pack from the computer.
❖ Do not try to disassemble a battery pack.
❖ Do not overcharge or reverse charge a battery. Overcharging
will shorten its life, and reverse charging could damage it.
❖ Avoid touching the metal terminals of the battery with another
metal object. Short-circuiting the battery can cause it to
overheat and may cause damage to the battery or the computer.
