Precautions
On Using the Battery Pack
Do not leave battery packs in temperatures above 140°F (60°C), such as in a car parked in the sun or under direct
sunlight.
Battery life is shorter in a cold environment. This is due to decreased battery efficiency at low temperatures.
Charge battery packs at temperatures between 50°F to 86°F (10°C to 30°C). Lower temperatures require longer charging
time.
This computer is designed to operate only with genuine Sony batteries.
While the battery pack is in use or being charged, heat builds up in the battery pack. This is normal and is not cause for
concern.
Keep the battery pack away from all sources of heat.
Keep the battery pack dry.
Do not open or try to disassemble the battery pack.
Do not expose the battery pack to any mechanical shock.
If you are not using your computer for a long period of time, remove the battery pack from the computer to prevent damage
to the battery pack.
If, after fully charging the battery pack, the battery power is still low, the battery pack may be reaching the end of its life
and should be replaced.
You do not need to discharge the battery pack before recharging.
If you have not used the battery pack for a considerable amount of time, recharge the battery pack.
