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 12248 BatteryMINDer
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 sulphated, 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 sulphation
