Battery Fault Analysis
Fault
Negative Phenomena
Cause
Handling Methods
Battery Short
Circuit
1. Low static voltage below 2V
2. Electrolyte density is too low
3. High temperature during
charging
4. Truck is with short working
time
1. Electrode plate deformed and
short circuit
2. Spacer missing or broken
during assembly
3. Positive electrode active
substances shedding, short
circuit at bottom
Battery needs to be replaced
Broken
circuits
1. Abnormal and unstable
voltage upon external
connection with load
2. Current fails to input when
charging
1. Poor welding during assembly
of electrode pole or electrode
plate
2. External short circuit
3. Large current discharge
4. Poor wiring connection or
disconnected
5. Electrode plate corrosion
1. Battery needs to be repaired
2. Battery needs to be
replaced if necessary
Battery
Reverse
Electrodes
1. Negative voltage values
2. Electrolyte density is lower
than 1.20g/cm3 after
charging
3. Positive and negative
electrode lugs, colors of
electrode plates are
reversed
Wrong connections of positive
and negative electrodes during
charging
1. Reverse charging is
allowable
2. Battery needs to be
replaced in severe situations
Battery Leaks 1. Filling hole leaks
2. Leaks at sealing seams of
tank and
fi
lling cap
3. Drainage
4. Marks of bumps on external
surface of tank
1. Tank,
fi
lling cap with poor
heat sealing
2. Electrode lug rubber ring
problems
3. Sealing compound cracked
4 External impact due to
negligence during use
1. Repair
2. Battery needs to be
replaced if necessary
