6.3.8 Handle waste battery
Waste battery should be handled properly in line with relevant laws and
regulations.
6.4 Troubleshooting
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:
1. Rated capacity not being
reached or not enough.
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.
3. Capacity drops suddenly.
The inner or outer short
circuit of battery
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.
