Battery Fault Analysis
Fault Negative Phenomena Cause Handling Methods
Insu󰀩cient
Battery
Charge
1. Low static voltage
2. Low density, cannot meet
the requirements after being
charged
3. Short working time
4. When running, the instrume-
nt displays quick drop of
capacity
1. Charger voltage and current
are set too low
2. Insu󰀩cient initial charge
3. Charger failure
1. Adjust and repair the
charger
2. Battery supplemental
charge
3. Battery needs to be
replaced in severe
situations
Electrolyte
has been
improperly
added to
the battery
- In case of high intensity:
1. Electrolyte density is not
less than 1.300g/cm3 after
charging
2. Battery static voltage is
higher
3. Initial capacity is good, but
reduced after a period of use
4. Electrolyte is turbid
- Low density:
1. Electrolyte density is still
lower than the specied
value after charging
2. Battery capacity is low
- Adding impure liquid:
1. Battery capacity is low
2. Electrolyte is turbid and of
abnormal color
3. Battery with severe self-
discharge
1. Initial adding of electrolyte
with excessive high or low
density
2. Liquid level reduces, adding
errors, failed to add pure water
in accordance with provisions,
but mistakenly adding dilute
acid
3. Initial adding of liquid is
impure (containing impurities
and with odor)
1. Replace the battery
electrolyte
2. Battery needs to be
replaced in severe
situations
