If you are using a modern IU0U-Charger you can set boost charge voltage to 2.40Vpc.
Make sure the 1
st
phase is limited to 10 hours.
If the battery temperature in the workshop deviates permanently more than 5°C, the
charge voltage should be adjusted in accordance with 7.2.3 “Temperature compensation
of the charging voltage”.
The recharging duration for a battery depends on its discharge state (depth of discharge,
discharge time). Recharging a completely discharged battery with the IU charging will
take:
approx.
9 Hours for 75% of the capacity
approx. 14 Hours for 85% of the capacity
approx. 30 Hours for 100% of the capacity.
With higher charging current and a boost charge phase you can expect shorter duration.
When the battery is fully charged with the recommended charge voltage the continuous
charging current is about 1mA/Ah. Over of the service life of the battery this trickle
charging current can increase up to 6mA/Ah. The prolongation of the trickle charging
during 48 to 72 hours will help to maintain the electrochemistry of your battery.
8.6.2 Equalization charge
The 2V ZeMa single cells do not require periodic equalization charging. In VRLA batteries
stratification should not occur. After a deep discharge or when voltage differences of the
cells indicate a sulfation, an equalisation charge can be considered.
This treatment is performed on the previously fully charged battery after a break of at
least one hour (gassing, cooling down) and requires a special charging rectifier.
The procedure applies for a limited period a small charging current (<10% I
10)
to the
series-connected 2V cells. During this charge with constant-current the voltage limit is
increased to 2.8 Vpc.

During this procedure you have to observe the battery for thermal reaction. If a battery
cell exceeds the temperature of 45°C you must interrupt the equalisation charge.
Limit the duration of the equalisation charge to 10 hours. Long exposure to equalisation
charge can damage the battery and consume a considerable share of its service life.
