With the development of the logistics industry, the forklift market has also ushered in the spring of the industry. In recent years, the production and sales of forklifts have continued to rise at an average annual rate of 30% to 40%. For forklifts, the forklift battery is the power source of the forklift. Therefore, if the forklift can work normally and have a long service life, the maintenance of the battery is very important.

The storage temperature is 5-45℃, and it should be in a clean and dry room with regular ventilation;

Supplement the battery with the second stage current of normal charging every 30 days;

Avoid direct sunlight, keep away from heat sources, and avoid damp, water-ingressing and completely enclosed places;

The dust falling on the traction battery cover and the electrolyte dripping on the traction battery during the measurement process should be wiped with 5-10% soda solution and tap water in time to keep the outer surface of the traction battery clean and dry.

2. Precautions during use

When the battery is used for the first time, it may not reach the rated capacity of the battery, and it will reach the normal capacity after about 5-10 full charge, use, and discharge cycles;

The electrolyte in the battery is highly corrosive, and protective equipment must be worn during operation;

When installing the battery, it is best to use a suitable sling to make the battery install smoothly and prevent battery damage and electrolyte splashing;

When the battery is in use, it should be prevented from over-discharge and long-time high-current discharge, otherwise it will affect the service life of the battery, and in severe cases, it may cause the connection line and cable to be overheated and burned;

In order to ensure the normal life of the battery, its discharge capacity (depth of discharge) shall not exceed 80% of the rated capacity. The battery must be recharged in time after it is discharged, and the battery must be fully charged before it can be used again. Frequent intermittent charging will affect the battery capacity And life;

The battery should have a good ventilation environment when charging. The charging area must not be a dangerous area. If there is an open flame, there are flammable and explosive gases and other areas. After a period of time, more precipitation, when the concentration of hydrogen in the air reaches 4%-75%, it will explode when it encounters an open flame);

When charging, make sure that there is no cover on the battery. At the same time, the liquid injection plug of each cell must be opened to dissipate the hydrogen as soon as possible;

During charging, the electrolyte temperature should not exceed 50℃, otherwise, try to cool down. If the temperature does not drop, stop charging and continue charging after the temperature drops. (During battery use, if the electrolyte temperature is too high, it will aggravate hydrogen Precipitation, reducing the bonding strength of the active material and the grid, increasing the corrosion of the electrolyte to the electrode plate, seriously affecting the service life of the traction battery and causing premature aging of the rubber sealing ring).


Forklift batteries have two options: automatic water filling and gas stirring systems. During battery charging and discharging, the electrolyte (dilute sulfuric acid) participates in the chemical reaction, which will easily cause the difference in the specific gravity of the upper and lower electrolytes of the battery, which is unfavorable for the charging and discharging performance of the battery. The Leoch forklift battery gas stirring system starts the pump after the charging voltage of the battery reaches a certain value, pumps the gas from one side of the battery, and stirs the electrolyte evenly through gas circulation, eliminating stratification, and improving the charging and discharging performance of the battery. . Leoch forklift battery has super strong cycle and deep discharge recovery ability, can achieve 80% DOD cycle up to 1500 times, has a longer storage period, and has a longer cycle life.

3. Maintenance of forklift battery

Regularly check whether there is any accumulation in the battery box (for battery packs without acid drain holes). If there is any accumulation, use a plastic slender tube to suck it out. At the same time, wipe off the liquid on the battery surface to prevent short circuits.

Use a damp cloth to clean the surface of the battery pack regularly. Do not use dry cloths (the dry cloth may cause accidents due to static electricity during use). It is recommended to thoroughly clean the surface of the battery pack every 2 weeks.

Measure and check the battery voltage, electrolyte density and temperature not less than once a week. In order to fully understand the status of the traction battery pack, a general inspection and general measurement shall be carried out once a month. The general inspection content is: whether the connection is tight, the electrolyte level, whether the density is normal, whether the voltage is balanced, etc., especially for batteries that use smart charging, the inspection of the battery is often neglected, and the individual problematic battery is not found. , Thereby affecting the performance of the entire battery pack.
Forklift battery

If the battery is not used for a long time, it is necessary to ensure that it is recharged once every two weeks, and the battery pack should be charged once a month.

In the process of battery inspection and measurement, it is strictly forbidden to step on or hit the battery cover, liquid filling cover and other traction battery components to prevent damage; it is strictly forbidden to place maintenance tools (wrenches, pliers, etc.) on the battery pack.

Three points of maintenance, seven points of quality, as we all know, the quality of the battery is the primary factor that determines the length of the service life. Leoch forklift battery adopts foreign advanced die-casting molding technology to delay grid corrosion speed and uses unique pole double sealing structure and anti-pole plate rising design to ensure no acid leakage during use, ensure reliable pole sealing, and unique exhaust The tube design improves the service life of the battery, which can be described as the ultimate quality and super long life.
