NOTE
If use of the power tool continues, battery discharge is stopped automatically
(indicated by LED 1 blinking) before the battery cells suffer damage.
Charge the battery with the Hilti charger approved 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. Avoid charging the battery in places subject to high ambient
temperatures (e.g. at a window) as this 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 possible to continue working with a
battery in this condition but it should be replaced in good time.
