Symptom Cause Corrective Action
The charger blows the branch
circuit fuse/circuit breaker a
short while after being switched
on. The branch circuit is too
small. Relocate charger to a branch
circuit with a heavier rating, or
remove other loads on the circuit.
Batteries use water, get hot, or
smell. One or more dead cells.
Dip switch not set correctly. Replace batteries. If charging in a
series string, it is best to replace all
the batteries rather than mix new
with old.
If shallow discharging, check that
the dip switch is not set to
standard, or extended cycle.
Voltage rises quickly on
battery(s) and the amps fall fast
even though they are dead. The batteries are sulfated. Sometimes batteries can be
recovered. Leave the charger on
for some hours, if the voltage falls
and the current begins to rise, it
may be able to be recovered.
