Troubleshooting - Model 12248
We use the word “Indicator” to
mean the various LEDs (Light
Emitting Diodes) showing the
various faults, modes, and
conditions of the battery and / or
charger.
The words “unit”, “charger” or
“recharger” means your model

Problem:
Power ON indicator does not light
Solution:
Check electrical outlet. If controlled
by a wall switch be sure switch is
on and try to prevent accidental
shutting it off while charger is
working.
Problem:
ERROR indicator lights
RED
(several possibilities can be the
cause)
Solution:
1. Output leads - connections to
battery may be reversed. Switch
(reverse) connections at battery
2. If still remains
RED
check
battery voltage. If 3-Volts or less
battery may be damaged and
should not be recharged. If battery
was just recently removed from a
load (headlights, door lights, etc.
or vehicle not used for extended
time without a charger-maintainer,
allow battery to “recover” by letting
it “rest” without a load. If battery is
healthy and just deeply discharged
it should recover its voltage (rise
above 3 volts) sufficiently to allow
charger to begin an attempt to
fully recharge it. If after battery has
“rested” (see pg. 9) it may not be
able to be recovered – recharged.
It should be safely discarded
– recycled.
Problem:
ERROR Indicator lights
RED
and
is
blinking
Solution:
1. Battery(s) may be weak,
heavily sulfated, or too large to
fully charge before unit times
out. Allow battery to remain in
Maintenance-Float mode for 72
hours or more and then attempt to
recharge again.
2. Battery may be so large it may
require a second full recharge.
Repeat recharge by pressing
and holding Stop/Restart for 5
sec. untill ALL LEDs light. Reset
charge rate and battery type, if
needed.
3. If recharging multiple batteries,
2 or more complete recharge
cycles may be needed. Repeat
full recharge by pressing Stop/
Restart button again. If still
RED
- blinking, you may need to charge
each battery separately.
Problem:
Battery Condition Indicator lights
YELLOW
(After battery has been completely
charged)
Solution:
Battery still has an unacceptable
level of sulfation and must stay
