6. Before use
A new battery must be charged correctly for the first
time before use:
– charged normally for 24 hours with the SFC 7/18 H
charger, or
– charged for 12 hours using the conditioning function
of the SFC 7/18, C7/24 or TCU 7/36 charger. This will
ensure that the cells form correctly. Incorrect initial
charging may have a permanent, negative effect on
battery capa city.

– 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.
