8.6.3 Recharging after deep discharge
Recharging after an accidental deep discharge may take too long in the vehicle and
disrupt the daily service.
Recharge a completely discharged battery as soon as possible in the workshop at 20°C
with a reduced current of I
24
(
ZeMa200P18*: 9.8 A
) for 26 hours. Limit the charge voltage
to 2.35 Vpc:
After this step adjust the charging rectifier back to trickle charging voltage of 2.29 Vpc. A
subsequent recharging for at least 72 hours will help to maintain the electrochemistry of
your battery.

* Charging current relates to the cell capacity, for other cells refer to the data sheets
After a correct recharge of the battery, it will then be ready for service. With a capacity
test (8.3 "Capacity test") you can verify the functionality. Note that each deep discharge is
stressing the battery and consumes its life endurance over proportionately.
