6.4 Troubleshooting guide
There are lots of reasons for the troubles, besides production quality or transportation
and storage, unsuitable maintenance will lead to many troubles. After the failure launch,
it’s necessary to analyze and take effective measures to remedy as soon as possible. The
features, reasons and troubleshooting of the common troubles are as follow:
Feature
Cause
Remedy
Capacity
drops
1. Rated capacity not
being reached or not
enough.
Not enough charge.
Balanced charging,
improve the operating
way.
Density of
electrolyte is too
low.
Adjust the density of
electrolyte.
The connecting line
isn’t clear, too high
resistance.
Unblock the outer
connection line and
reduce the resistance.
2. Capacity drops
gradually.
Pole plates are
sulphated
Charging repeatedly to
exhaust the condition of
sulphating.
There is harmful
matter in electrolyte.
Check electrolyte, replace
it if necessary.
The battery is
localized short
circuit.
Check and remove.
3.Capacity drops
suddenly.
The inner or outer
short circuit of
battery
Check and remove.
Voltage is
abnormal
1. The voltage is too
high when charging,
drops quickly when
discharging.
The pole plates are
sulphated
Exhaust the condition of
sulphating.
2. Opening voltage
reduces markedly.
Opposite pole,
short circuit.
Check signal voltage and
exhaust it.
