When powered up the
LED is solid red with a
yellow flash, and
displaying 02.
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
.)
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.
Profile 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
gassing/absorption
profile is set to
d1
After a full charge, the
batteries die quickly
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 is a good sign
they can recover under
normal charging.
