6.1 Battery use and care
en
NOTE
Battery performance drops at low temperatures. Never
use the battery until the cells become fully discharged.
Change to the second battery as soon as a drop in per-
formance is noticed. Recharge the battery immediately
so that it is ready for reuse.
Store the battery in a cool, dry place. Never store the
battery where it is exposed to the heat of the sun, on a
radiator or behind glass, e.g. at a window. Batteries that
have reached the end of their life must be disposed of
safely and correctly to avoid environmental pollution.
Insert the battery in the corresponding charger.
6.2 Charging the battery
CAUTION
Use only the Hilti chargers listed under "Accessories".
DANGER
Ensure that the outer surfaces of the battery are clean
and dry before inserting it in the corresponding char-
ger. Read the operating instructions for the charger
for further information about the charging procedure.
6.2.1 Charging a new battery for the first time
A new battery must be charged correctly for the first time
before use. This will ensure that the cells form correctly.
Incorrect initial charging may have a permanent, negative
effect on battery capacity. Please refer to the applicable
battery charger's operating instructions for information
about initial charging.
