The battery voltage
reads well below the
rating of the battery, and
when powered up the
LED is red with a
yellow flash, and the
amps are less than 5.
The battery is very low,
and the charger is in a
slow charge phase until
the voltage rises to a safe
level before full turn on.
Leave connected, it may
take hours, but if the
voltage rises even a little
bit, it should recover,
and turn the charger full
on.
(Do not allow your
batteries to deep
discharge, it is the
number one cause of
premature battery
failure
.)
When switched on, the
LED flashes red/yellow,
and there is no amp
output on the meter
Charger and battery
voltage mismatch
Connect the charger to a
battery(s) with the same
voltage rating.
The charger blows it’s
fuse, or branch circuit
fuse/circuit breaker as
soon as it’s switched on.
Charger is shorted
Contact factory.
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.
