Forklift battery is the main power source of forklift. Electric forklift has low price and mature market. As a deep cycle battery for forklifts, any type of lead-acid battery will self-discharge. Self-discharge and gradual vulcanization of plates are inevitable. The "gradual failure", as the requirements for product materials and technology are becoming more stringent, such as lead-bismuth alloy lead-calcium alloy, and gradually become "completely maintenance-free."

When the forklift battery is used for a certain period of time, there will be problems such as frequent water supply or excessive power consumption and short use time. This time, you need to consider whether to purchase or repair the entire battery this year, usually the battery pack will be broken within 2 years. Within five, you can consider replacing the monomer, preferably the same type of battery pack of the same manufacturer, to avoid the unevenness of the forklift battery purchased and the welding is not strong. More than 2 years, the replacement of the monomer is not significant, the more the battery vulcanization over time, the replacement of the monomer and the old battery capacity will be inconsistent, charging and discharging is not balanced, in order to avoid major problems, it is recommended to replace the entire group.



Some people are accustomed to using a voltmeter or a multimeter's voltage file without load to check if the battery is fully charged, which is very unreliable. Because even if the discharge end of the battery is activated, once the discharge between the positive and negative terminals of the battery stops and the electrolyte immediately reaches the potential of the open circuit voltage, the potential difference between them can be immediately restored, about 2.1V per cell, and the entire battery is about 12.6V or more. . If you only measure the voltage, it consumes very little current, it will not drop in the battery, so the voltage is not low, but if the load increases, such as headlights (10 ~ 15A), speakers (6 ~ 12A), the battery will The lights are dim and the horns are hoarse, which indicates a lack of power storage.

If the battery forklift relies on the battery to operate, consider the possible factors of the vehicle load. For example, if the load is free to slide too fast, the valve spool or the seal ring of the oil leakage multi-way valve may be worn and the inner leakage may occur. The Y-ring seal of the lift cylinder piston support ring wears out, causing internal leakage. If the fault and the brake part are eliminated, the battery forklift needs to be disassembled, and the details determine success or failure. For different fuel operated forklifts, electric forklifts experience minimal wear during operation. It is a fact that electric motors have fewer working parts, but they also need regular lubrication to prevent wear.

If the forklift battery does not reach the rated capacity or capacity during use, first consider the battery is insufficiently charged or insufficiently charged after use. Check whether the electrolyte density is low and whether there is a density increase after charging. If the density is constant, consider The external wiring is not smooth and the resistance is large. Therefore, we have to carry out professional charging operations, charging requires analysis of various charging technologies. The basic requirement for charging is that the charging current should be less than or equal to the charging current that the battery can receive. Otherwise, the overcurrent will cause the water electrolyte to be consumed quickly, resulting in the following hazards: increasing the water loss rate of the forklift battery, increasing the maintenance workload of the maintenance-free battery, the battery forklift will cause early failure; causing environmental pollution and endangering the health of the worker; charging Reduced efficiency, resulting in a serious waste of energy.

In the maintenance of this piece, there are many problems to be aware of, paying attention to observe the circuit power change can save more time, it is, however, still must follow the maintenance and maintenance to reduce the need for electric forklift maintenance, further explanation, in general, maintenance is A time-consuming thing, enough maintenance, to avoid the replacement of more forklift parts in the later period. A matter that we must check after the charging work is completed to ensure the service life of the forklift battery.
