Low
1: No rated capacity or insufficient capacity
Insufficient supplementation or insufficient charging after use
Balance charging and improve operation method
Electrolyte density is low
Adjusting electrolyte density
External lines are not smooth, large resistance
Treat out the line, reduce the resistance.
2: Capacity gradually decrease
Polar sulfate
Repeated charging, eliminate the plate sulfate ratio.
Electrolyte mixed into harmful impurities
Battery local short circuit
exclude
3: The capacity suddenly decreases
Battery internal or external short circuit
Check reason and exclude
Electricity
Press
different
often
1: The voltage is high when the battery is charged, and the voltage is lowered when the discharge is discharged.
Polar sulfate
Eliminate plateal sulfate
2: The battery is in use, the open circuit voltage is significantly reduced.
Negative, short circuit
Check the unit cell voltage and exclude.
Take
gas
different
often
1: The battery is not taking gas or less
Charging current is too small or battery charging is not sufficient
Adjust the charging current and mechanically charge.
2: The battery is ventilated after charging
Battery internal short circuit
Troubleshift
3: The battery is too early in charging and has a lot of gas
Polar sulfate
Eliminate plateal sulfate
4: The battery is placed or venting during the discharge process.
If the charge is not placed, it is discharged, and there is impurities in the electrolyte.
Return of an hour or so discharge or replace the electrolyte
Temperature
Decline
Height
1: When charging is charged, the liquid temperature increases.
Too big or internal short circuit when charging
Adjust the charging current or exclude short circuit
2: Individual battery temperature is generally high
Polar sulfate
Eliminate plateal sulfate

Solve
Liquid color
Deceased
Regular
1: The battery has less density in the charging.
Polar sulfate
Eliminate plateal sulfate
2: After the battery is charged, the density is lowered during the shelving.
Battery self-discharge
Electrolytic liquid should be replaced more
3: The electrolyte color, the smell is abnormal, and there is a turbid precipitate.
The electrolyte is not pure, and the active material is falling off.
Replace the electrolyte and flush the interior of the battery
