9.4.5 Faults and remedies

Fault observed
The acid heats up when a new battery is
filled
The acid escapes through the filler holes
Acid level too low
Acid level too low
Incorrect operation from start-up
Acid density too high
Starting problems
Starting test incorrect
Battery terminals melted
One or two cells release a lot of gas at
high charge
The battery discharges very quickly
Short service life
High water consumption
The battery explodes
Probable origin
- Incorrect composition
- Incorrect storage
- Prolonged storage in a damp place
- Battery overflow during filling
- Battery tray not leaktight
- Significant gas formation caused by
too high a charging voltage
- Insufficient charge
- Short circuit in the current circuit
- Consumption fault
- The battery has been filled with acid
instead of water
- Battery empty
- Battery used up or faulty
- Capacity too low
- Battery sulphated
- Incorrect electrical connection
- Incorrect battery wiring
- Cell(s) faulty
- Charge status too low
- Short circuit in the current circuit
- High self-discharge (for example:
through electrolyte contamination)
- Sulphation (storage of discharged
battery)
- Incorrect battery part no.
- Too many repeated deep discharges
- Battery stored too long
charge
- Overload
- Charging voltage too high
- Spark after battery charging
- Short circuit
- Connection or disconnection during
charging
- Internal fault (for
interruption) and low electrolyte level

Measures or observations
- Cool
- Charge
- Check the acid density
- Reduce the battery fluid level
- Replace the battery
- Check the charger and repair if
necessary.
- Recharge
- Check the electrical installation
- Reduce the acid level and fill with
distilled water. Repeat the operation if
need be.
- Recharge the battery
- Fit a new battery
- Tighten the ends of the battery
cables, or replace them if necessary
- Fit a new battery
- Check the charge
- Replace the battery
- Define the correct battery part no. for
the recommended use
without - Think about charging the battery
using a regulator
- Check the charger (voltage regulator)
- Replace the battery (beware of fire
and sparks)
- Ensure there is sufficient ventilation
