Troubleshooting - Model E12248-AA-S2
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 E12248-AA-S2 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 -Volts or less
battery may be damaged and should not be recharged. If battery
was just recently removed from a load (lights, electronic equip-
ment) or not used for extended time without a charger-maintain-
er, 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 6 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.
