Keep the battery pack away from all sources of heat.
❑
Keep the battery pack dry.
❑

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.

pack may be reaching the end of its life and should be replaced.
