Make sure the battery is fully charged
before use.

clean, soft, dry cloth.
The battery may be warm during use or
recharging. This is normal.
When storing the battery for an extended
period, be sure that it is not completely
charged, nor completely discharged.
The ideal level is a 40% charge. This is
approximate; the closer the battery is
to this level, the better it will hold its
charge during storage. The battery
should be stored in a cool, dry place. The
recommended temperature for storage
is 59°F (15°C). You may store a battery
in a refrigerator. Do not store batteries
in a freezer.
Remove the battery from your equipment
when not in use. Some electronic
equipment will draw current even when
the switch is off.
