Troubleshooting - Model 12248-AA-S1
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-AA-S1 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 (lights, electronic equipment)
or 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 bat-
tery has “rested” (see pg. 9) it may not be able to
be recovered – recharged. It should be safely dis-
carded – 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 bat-
tery 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 hold-
ing START/RESET/STOP for 5 sec. until ALL LEDs
light. Reset charge rate and battery type, if needed.
Press START button to begin full recharge.
