Charging the battery
Requirements
– Electrolyte temperature b15°C and +35°C
Procedure
• Open or take off the tray lid or covers from the battery compartment.
• Connect the battery to the switched off charger, ensuring the terminals are connect
(positive to positive and negative to negative).
• Switch on the charger.
Z
The electrolyte temperature rises by approx. 10°C during charging. If the
temperatures are permanently higher than 40°C or lower than 15°C, a temperature-
dependent constant voltage control of the charger is required. The adjustment
factor must be applied with -0.004 V/C per °C.
The battery is charged.
Z
Charging is considered to be complete when the electrolyte density and battery
voltage remain constant for more than 2 hours.
Compensation charging
Compensation charging is used to ensure the useful life and maintain capacity after
full discharge and repeated insufficient charging.
Z
Compensation charging should be carried out weekly.
Trickle charging
Battery trickle charging is partial charging that extends the daily application time.
Higher average temperatures occur during trickle charging which can reduce the
useful life of the batteries.
Z
Trickle charges should only be performed when the charge level is below 50%.
Use replacement batteries instead of regular trickle charging.
Z
Avoid trickle charging with PzV batteries.
