Feature
Cause
Remedy
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.
Repair the short circuit
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 impurity 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.
Quick self-discharging.
Many impurities are 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, m
aking the battery keep
in the critical state of optimal charging electrochemical reaction.
