3.2 Weekly
Visual inspection after recharging for signs of dirt and mechanical damage.
3.3 Quarterly
After the end of the charge and a rest time of 5 h following should be measured and
recorded:
• the voltages of the battery
• the voltages of every cells
If significant changes from earlier measurements or differences between the cells or
bloc batteries are found, further testing and maintenance by the service department
should be requested.
3.4 Annually
In accordance with DIN VDE 0117 at least once per year, the insulation resistance of
the truck and the battery must be checked by an electrical specialist.
The tests on the insulation resistance of the battery must be conducted in accordance
with DIN 43539-1.
The insulation resistance of the battery thus determined must not be below a value of
50
Ω per Volt of nominal voltage, in compliance with DIN EN 50272-3.
For batteries up to 20 V nominal voltage the minimum value is 1000 Ω .
4. Care of the battery
The battery should always be kept clean and dry to prevent tracking currents. Clea-
ning must be done in accordance with the ZVEI code of practice «The Cleaning of
Vehicle Traction batteries».
Any liquid in the battery tray must be extracted and disposed of in the prescribed man-
ner.
Damage to the insulation of the tray should be repaired after cleaning, to ensure that
the insulation value complies with DIN EN 50272-3 and to prevent tray corrosion. If it
is necessary to remove cells it is best to call our service department for this.
5. Storage
If batteries are taken out of service for a lengthy period they should be stored in the
fully charged condition in a dry, frost-free room.
To ensure the battery is always ready for use a choice of charging methods can be
made:
1. a quarterly full charging like charge as in point 2.2. If any consumer is connected
with, e.g. measure or controlling systems, it can be, that this charging is necessary
every 14 days.
2. float charging at a charging voltage of 2.25 V x the number of cells.
The storage time should be taken into account when considering the life of the batte-
ry.
