NOTE
The charge status display on the battery is deactivated when the battery is
inserted in the charger.
Check that the battery and charger interfaces match (keyed fit).
Charging begins automatically after insertion of the battery in the charger.
NOTE
The battery will suffer no damage even when left in the charger for long
periods. In this case it is necessary that the charger is in a powered-on state
(LED 1 of the status display lights green). For safety reasons, however, it is
recommended that the battery is removed from the charger after completion
of charging.
6.2 Removing the battery 3
1. Pull the battery out of the tool.
6.3 Care of the Li-ion battery
Avoid ingress of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging the battery as
soon as a significant drop in battery performance is noticed.
NOTE
If use continues, further battery discharge will be stopped automatically
before the battery cells suffer damage.
Charge the battery using an approved charger from Hilti designed for use
with Li-ion batteries.
NOTE
– A conditioning charge (as is required with NiCd or NiMH batteries) is
not necessary.
– Interruption of the charging procedure has no negative effect on
battery life.
– Charging can be started at any time with no negative effect on battery
life. There is no memory effect (as with NiCd or NiMH batteries).
– For best results, batteries should be stored fully charged in a cool
dry place. Storing the battery in places subject to high ambient
temperatures (e.g. at a window) has an adverse effect on battery life
and increases the rate of self-discharge.
– If the battery no longer reaches full charge, it may have lost capacity
due to aging or overstressing. It is still possible to work with this
battery. You should, however, soon replace the batterywithanewone.
