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.
