Battery Life
Never charge batteries at temperatures below 32° F (0° C) or above
104°F (40° C). Do not charge batteries in an environment which has
high air humidity or at a high ambient temperature. Do not cover
batteries and/or the battery charger during the charging process.
It is normal for the battery and charger to heat up during the
charging process.
Lithium ion batteries do not exhibit the well known “memory effect”.
However each battery should be fully recharged before use.
Follow the instructions for charging the battery in the operating
instructions for the electric power tool and the battery charger.
Reduced operating times after recharging indicates that the battery
is worn out and may need to be replaced.
If the batteries are not used for a prolonged period, store batteries
partially charged and in a cool location 50° - 77° F (10° - 25°C).
