On using the battery pack
❑Never leave the battery pack in temperatures above 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 the batteries at temperatures between 10°C to 30°C. Lower temperatures require a longer charging time.
❑While the battery is in use or being discharged, the battery pack heats up. This is normal and is not cause for concern.

❑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 the computer for an extended period of time, remove the battery pack from the computer to prevent damage to the battery.
❑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 before recharging.
❑If you have not used the battery pack for a considerable amount of time, recharge the battery.
