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 tem-
peratures (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 over-
stressing. It is still possible to work with this
battery. You should, however, soon replace
the battery with a new one.
