of grounding protection line of charger should be ensured to prevent the electric
shock accident.
(4) Pulling out battery connectors should be avoided when charger is not
turned off. Special care should be taken as this will make battery undercharged
which produces dangerous electric spark.
4.5.5 Fault and troubleshooting
The causes that make the battery fault are various, except the quality manufacture
and transport storage, mostly due to the improper maintenance. Find out faults and
analyze the causation in time, take effective measure as soon as possible to exclude.
Table 4-4 Fault and troubleshoot of battery
1) Decrease of the battery
capacity.
2) Low density of the
electrolytic ( below the
normal lever).
3) High battery voltage when
beginning or finishing the
charging.
4) Air bubble in the early
time of charging or
beginning.
5) High rising of the
electrolytic temperature
when charging.
1) Inefficient first charging.
2) Inefficient charging for a
long time.
3) Discharging for many
times.
4) No timely charging after
discharging.
5) High density of the
electrolytic.
6) Low lever of electrolytic.
7) No timely balanced
charging.
8) Too low or high
discharging current.
9)Impure of the
electrolytic.
10) Short inside or
creepage.
1) Adopt the measure
of balanced charging
when the actuality is
not severity.
2) Adopt the
hydrotherapeutics
when the actuality is
severity.
3) Do not over
discharging.
4) The density of the
electrolytic should
below the regular lever.
5) The lever of the
electrolytic and content
of the impurity should
be in the prescribed
range.
1) Low battery voltage or
close to zero indeed when
charging.
2) Few or no air bubble at
the end of the charging.
3) High rising of electrolytic
temperature or slow or no
rising of electrolytic density.
4) Low battery voltage under
the condition of open circuit
or a quick drop to the limit
value when discharging.
5)Serious self-discharging.
1) Curve pole plate;
expanded reactive matter;
desquamated reactive
matter.
2) Much precipitate.
3) Falling of conductor to
the battery.
1) Replace the plate.
2) Clean the precipitate
and conductor.
3) Replace the plate.
