Fault Indications And Troubleshooting - Exide 12/4 User Manual

recommended battery size or in connection with other equipment
drawing current (parallel load) being connected to the battery dur-
ing charging.
Batteries can be damaged by being charged at high temperatures,
so the charger has been fitted with a safety function that interrupts
charging when temperatures are too high, approx. 50 °C.
Information about faults and fault indications is explained in the
table below.

Fault: The LED shows constant red when the charger cable
1.
clamps are connected to the battery terminal posts.
Probable cause: If the cable clamps are incorrectly connected
to the battery, the polarity reversal protection will be activated and
charging will not start.
Action: Check that the charger is connected using the correct polarity.
2.
Fault: Charging does not start, i.e. the lamp continues to light,
and the LED does not change to the constant orange light.
Probable cause: The battery voltage is too low to start the
charger. This may be because the battery is worn or faulty or
has been completely discharged.
Action: Sometimes it may help to connect a functioning battery
in parallel, as when using jump cables. If so: first disconnect the
charger, then connect the batteries to each other by connecting
their positive terminal posts (+) together using a jump cable, and
then connecting the negative terminal posts (-) using the other
jump cable. Then connect the charger and retry the process. If
charging starts, disconnect the jump leads and allow charging
to continue until the battery is fully charged. If charging does not
begin the battery is probably defective and should be replaced.
3.
Fault: Charging started normally, but did not complete. Instead,
the LED changed to constant red light and charging is terminated.
Probable cause 1: Defective or worn battery. The battery has a
fault that does not permit it to be charged, e.g. a short circuit.
Action: Replace the battery.
