6. Before use

It is essential that a new battery is charged correctly
before initial use so that the battery cells can form cor-
rectly. Incorrect initial charging can lead to a permanent
reduction of battery capacity.
– With the C 7/24 or TCU 7/36 charger: Charge for 24
hours in normal charging mode or for 12 hours in con-
ditioning (refresh) mode.
– With the C 7/36-ACS charger: The charger detects
automatically whether initial charging or normal charg-
ing is necessary.
-NOTE-
– The tool may be used only with B24/2.0 NiCd, B24/2.4
NiCd or B24/3.0 NiMH batteries.
– Battery performance drops at low temperatures.
– Batteries should be stored at room temperature.
– Never store batteries where they are exposed to the
heat of the sun, on a radiator, behind a motor vehicle
windscreen or at a window.
– Never use the battery until the cells become fully dis-
charged. Change to the second battery as soon as a
drop in performance is noticed and recharge the bat-
tery immediately so that it is ready for re-use.
