PERFORMANCE
• Make sure the battery is fully charged
before use.
• Clean the battery and terminals with a
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.
