The absorption time is too short. For
adaptive charging this can be caused by
an extremely high charging current with
respect to battery capacity, so that bulk
time is insufficient.
Reduce the charging current or select the
'fixed' charging characteristics.
The battery is
overcharged.
The absorption voltage is set to an
incorrect level (too high).
Set the absorption voltage to the correct
level.
Poor battery connection. Check the battery connections.
The float voltage is set to an incorrect
level (too high).
Set the float voltage to the correct level.
Poor battery condition. Replace the battery.
The battery temperature is too high (due
to poor ventilation, excessively high
environmental temperature, or
excessively high charging current).
Improve ventilation, install batteries in a
cooler environment, reduce the charging
current,
and connect the temperature
sensor.
The charging current
drops to 0 as soon as the
absorption phase
initiates.
Defective battery temperature sensor
Disconnect the temperature sensor plug in
the MultiPlus-II GX. If charging functions
correctly after approximately 1 minute, the
temperature sensor should be replaced.
The battery is over-heated (+50°C) Install the battery in a cooler environment
Reduce the charging current
Check whether one of the battery cells has
an internal short circuit
