When to charge the battery pack
Charge your battery pack before you use
your tool for the first time and when your
tool no longer performs with the power
and torque needed for the job. Never com-
pletely discharge the battery pack.
New battery packs reach full loading ca-
pacity after 4-5 chargings and
dischargings. Battery packs which have
not been used for some time should be
recharged before use.
Standard charging times
Standard charging time is approximately
one hour. Charging time varies depending
on the battery temperature, charge needed
and the type of battery pack being
charged. For example, if the battery pack
does not require a full charge, the charg-
ing time will be less than one hour.
Effects of temperature on charging
Battery packs are affected by temperature.
The charger will sense battery temperature
and will charge the battery at the most rapid
rate when its temperature ideal (between
41°F (5°C) and 113°F (45°C). When the
battery temperature is outside of this range,
the charger will supply enough current to
keep the battery pack in its current state to
prevent damage to battery.
