Operation—Battery Charger (cont'd)
Appropriate Use of Battery Charger
• Make sure the terminals of the battery charger
are not contaminated with liquid, grease, or other
substances before charging the battery pack. If
you notice that the terminals of the battery charger
are contaminated, be sure to wipe or take them
off before use. The life of the battery pack may
adversely be affected when the terminals are
clogged with the dust or dirt which becomes solid
with liquid or grease.
• During charging, the charger may become slightly
warm. This is normal.

• If the temperature of the battery pack is 32 °F
(0 °C) or less, charging takes longer to fully charge
the battery pack than the standard charging time.
Even when the battery is fully charged, it will have
approximately 50% of the power of a fully charged
battery at normal operating temperature.
• If a fully charged battery pack is inserted into the
charger again, the charging lamp lights up. After
several minutes, the charging lamp may turn off to
indicate the charging is completed.
