6. Before use
6.1 Battery use and care
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 performance 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 direct sunlight or
sources of heat, e.g. on heaters / radiators or behind a
motor vehicle windscreen. Batteries that have reached
the end of their life must be disposed of safely and
correctly to avoid environmental pollution.
6.2 Charging the battery
CAUTION
Use only Hilti SFB 180 or SFB 185 batteries.
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.
6.2.2 Charging a previously used battery
CAUTION
Use only the Hilti chargers listed under “Accessor-
ies”.
Ensure that the outer surfaces of the battery are
clean and dry before inserting it in the corresponding
charger.
Read the operating instructions for the charger for
further information about the charging procedure.
6.3 Fitting the battery to the power tool
