Based on the above reactions, we can see, when the battery is

electrolyte. While being discharged, electrolyte level downs
because of sucking electrolyte. In addition,the separator has high
sucking capability, therefore, the electrolyte level changes a lot
during the process of charging and discharging. At the end of
charging (or over-discharging ), some water is electrolyzed to
produce oxygen and hydrogen.

As principle , ignore it when there is no
influences on operation,otherwise,replace it
with qualified new cell
The tight nuts are loosened
check if the wave washer (or spring washer )
are intact or not,change the defensive washer
with the qualified ones,then tighten the nuts
properly in accordance with manufacturer s
instructions
The cell capacity is lower than the
nominal capacity
Carry out charge-discharge cycle and check
the cell capacity
There is short-circuit between the
cells
Dissemble and clean the cell,then recharge
it in accordance with manufacturer s
instructions
The electrolyte is too little
Refill the distilled water and recharge the
cell,adjust the electrolyte level at the end
of charge
The joint parts is disconnected
Tighten the nut
Improper series connection
Check the wiring to shoot the troubles on
series connection,then charge and discharge
the cells in accordance with manufacturer s
instructions
Several cells is damaged
Replace the defective cells with qualified
new ones
Acidic atmosphere

lack of lubricating oil
clean and lubricate the metallic linking parts
of the cell properly
The nickel plated coating of the
metallic linking parts is damaged
Replace the damaged metallic linking parts
There is green or black substance on
the metallic linking parts
