Compared with fuel forklifts, electric forklifts have significant cost advantages, and are used more and more in logistics and production. Today, I will talk about the maintenance of electric forklift batteries.
The maintenance of the forklift battery is directly related to the final service life of the battery. The service life of the battery varies greatly. If the same battery is well maintained, a battery can be used for more than 5 years, but if the maintenance is not in place, the same battery 1-2 It is not uncommon for it to be scrapped within a year. Forklift batteries are expensive consumables. The price of a 48V500ah forklift battery ranges from 1.6w to 2.7w. The difference in battery life caused by maintenance will be very obvious and directly reflected in the cost of electric forklifts.
1.Battery charge and discharge
(1) Make sure not to discharge the battery below 40% during use.
(2) Make sure the battery is in a well-ventilated environment when charging.
(3) When charging, use a suitable charger to charge the battery at an appropriate voltage, and avoid charging the battery with an excessively high voltage.
(4) Cut off the power supply in time after charging is completed to avoid long-term floating charge of the battery.
(5) Balance charge the battery every 500 working hours (3-4 months) to activate the inert oxides accumulated on the plate during use.

2.Daily maintenance
(1) Detect the battery surface, terminals, and battery connection: determine whether there is corrosion crystallization, and whether the line connection is stable
(2) Clean the battery surface: Accumulation of dirt will lead to a short circuit on the battery surface, increase battery power consumption, and reduce battery standby and use time. Note here that you should use a wet towel to clean the surface of the battery. Wiping with a dry towel can easily cause static electricity on the battery surface or even spark a fire.
3.Add water to the battery for maintenance
The heat generated during battery use and charging will cause the moisture in the electrolyte to volatilize, and the electrolysis reaction accompanying charging will also cause the water to be electrolyzed into hydrogen and oxygen to reduce. Therefore, it is necessary to regularly check the battery liquid level, timely add water to the water-deficient battery cell, replenish the lost water, and ensure that the internal characteristics of the battery are kept in a healthy state.
(1) Pay attention to distilled water or deionized water when adding water for maintenance. Water containing impurities may increase the resistance of the electrolyte after entering the battery, resulting in increased battery power consumption, increased heat release from the battery box, and greatly reduced battery operating time and battery life.
(2) The amount of water added should be controlled at about 2cm from the liquid level to the battery outlet. Generally, most batteries on the market are equipped with a liquid injection valve with a liquid level indicator function, and distilled water can be filled according to the height indicated by the liquid injection valve.
(3) Pay attention to keep the liquid level of each battery compartment as balanced as possible when adding water. The difference in electrolyte level will lead to differences in battery characteristics, which will affect battery life in the long run.
