Battery Related Alarms
Over Discharged Battery -
Urgent
The battery is still under 1.9Vpc after 30 seconds of charge
and indicates a faulty battery that needs investigation.
Deeply Discharge Battery - Non-urgent
The battery initially is under 1.9Vpc but recovers within 30
seconds of the charge cycle start, this alarm normally
comes up when a battery is unplugged from the lift truck
and immediately plugged into the charger.
Sulphated Battery –
Urgent
The battery fails to complete a de-sulphation profile applied
by the charger correctly and generally means that the
battery requires attention.
Incorrect Battery -
Urgent
The battery is inappropriate for the configuration of the
charger and cannot be charged without reconfiguring the
charger to suit the battery.
Bulk Charge Timeout -
Urgent
The battery has exceeded the maximum time allowed for
the initial constant current bulk charge phase. Could
indicate a faulty battery or the charger configuration is not
correct for the size of battery to be charged. May need
additional charger modules added to the charger.
Finishing Charge Timeout - Non-urgent
The battery has exceeded the maximum time allowed for
the finishing part of the charge cycle. Generally not a
problem and indicates the battery did not quite perform as
expected. Not uncommon with new batteries that are still
cycling up to full capacity (allow 10 cycles) however if the
alarm is a regular occurrence it needs investigation and
possible adjustment of the charger or service of the battery.
Battery Disconnected -
Urgent
The battery has been unplugged before charge cycle has
complete. This can damage the battery connector and
increase risks of battery explosions as sparks around
batteries at their top of charge whilst gassing can be very
dangerous. If the battery needs to be disconnected mid
cycle, the toggle switch must be first set to
STOP
. This will
stop the charge and log a partial cycle in the charge log but
allows safe disconnection of the battery.
Reversed Battery –
Urgent
A battery with its positive and negative cables reversed has
been connected to the charger. Generally this will also
cause an output fuse alarm and the need to replace the
chargers DC output fuse(s). Such a situation is not covered
by warranty as new batteries should always first be
