General fault and remedy of electric forklift batteriesPhenomenon

feature

possible reason

Remedy

Allow

quantity

drop

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

Electricity and

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
