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 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 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.
