8.5. Fault finding

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
The battery is too full
Battery tray not leaktight
Considerable formation of gas due to a
very high charging voltage
Insufficient charge
Short circuit in the power circuit
Consumption fault
The battery has been filled with acid
instead of water
Battery empty
Battery exhausted or faulty
Capacity too low
Battery sulphated
Incorrect electrical connection
Battery cabling incorrect
Faulty cell(s)
Charge status too low
Short circuit in the power circuit
High self-discharge (for
through electrolyte contamination)
Sulphation (storage of
battery)
Incorrect battery part no
Repeated deep discharging
Battery stored too long without charge
Overload
Charging voltage too high
Sparks after battery charging
Short circuit
Connection or disconnection during
charging
Internal fault (for example: interruption)
and low electrolyte level
87/242
Measures or observations
Cool
Charge the battery
Check the acid density
Reduce the battery fluid level
Replace the battery
Check the
necessary
Recharge the battery
Check the electrical installation
Reduce the acid level and fill with
distilled water. Repeat the operation if
necessary
Recharge the battery
Replace the battery
Tighten the ends of the battery cables or
replace them if necessary and replace
the battery
Replace the battery
Check the load
example:
Replace the battery
discharged
Define the correct battery part no. for
the recommended use
It is recommended to charge the battery
using a regulator
Check the charger (voltage regulator).
Replace the battery
charger and repair if
