Abnormally
giving off gas
1. No gas or little
during the end stage
of charging.
Low charging
current or charging
not enough.
Adjust charging current
and go on charging
2. No gas after
charging.
Short circuit of the
inner battery.
3. Giving off too early
with large quantity
gas when charging.
Pole plates are
sulphated.
Exhaust the condition of
sulphating
4. Give off gas on the
process of laying or
charging.
No laying after
charging, or there is
matter in electrolyte.
Discharge or replace
electrolyte after laying for
1 hour.
Temperature
of electrolyte
is high
1. When charging
normally, the
temperature raises
abnormally.
Too large current or
short circuit when
charging.
Adjust the charging
current or exhaust the
short circuit.
2. Some batteries’
temperature is higher
than others.
Pole plates are
sulphated.
Exhaust the condition of
sulphating.
Color and
density of
electrolyte is
abnormal
1. Density rises less
or stays.
Pole plates are
sulphated
Exhaust the condition of
sulphating
2. After charging, the
density drops heavily
when storage.
Much matter is in
electrolyte, replace
electrolyte.
3. The color and
smell is abnormal,
and with turbid
sediment.
Electrolyte is not
pure, active matter
gives away.
Replace electrolyte and
clean the inner part
6.5 Charger
Charger consists of controller, power block and transformer. It adopts intelligent
closed cycle control, it can display the status of charge and fault, and can measure the
battery automatically. It’s with dynamic tracking, closed cycle controlling, making the
battery keep in the critical state of optimal charging electrochemical reaction.
