The battery forklift battery is a large class of lead-acid. With the growth of the use time, the hardness of lead will get higher and higher, and vulcanization has become serious. This is a major drawback of lead-acid batteries. If the lead purity of the forklift battery is not enough, or Producing in regenerated cartridge, the time of vulcanization will accelerate, leading to the decline in the last period of use, then there is no way to solve this problem? With the acceleration of domestic industrial development, industrial equipment, vehicle applications increased, each year my country consumes a lot of lead-acid battery, strictly not dealing with good or continuous battery life, and two contaminated, Belonst Battery from 2006 Starting to contact the forklift battery research and development, the polar vulcanization battery must be eliminated, otherwise it will affect the normal operation of the battery, depending on the degree of vulcanization, different methods can be eliminated. An industrial battery circulating in the market is approximately a simple step on vulcanization elimination:
1, small current charging method. The battery that is not very severe and severely severely severely severely charged, and the method is to carry out long time with a second stage of initial charging (about 1/30), or less current, (40 ~ 50H) is charged until it is sufficient, then the electricity is filled with a small current with a small current, so that the battery capacity meets the requirements (i.e., 80% rated capacity). The electrolyte density and height should be adjusted before use.
2, water treatment method. When the polar is more vulcanized, a “water treatment method” can be repaired. The method is to first discharge the battery for 20H discharge rate to a single battery of 1.75V, then pour out the electrolyte, and the distilled water is allowed to stand for 1 h, and then charging the current charging current. The density of the electrolyte is increased to 1.15 g / ml, and then discharged to the termination voltage according to the discharge current above. Then, charging is performed in the original charging current until the electrolyte density is no longer rising. As so much, when the battery capacity reaches 80% of the rated capacity, the processing is basically completed. Adjusting the electrolyte density (1.28 g / ml) and the liquid level can be used.
3, chemical treatment method. For a long-sulfurized battery, a method of adding a chemical agent can be used to sulfur. The method is: first discharge the battery with a 20H discharge rate, pour the electrolyte, and then rinse it once with distilled water, then the electrolytic solution having a density of 1.100-1.150, add 0.1% -0.5 in the electrolyte. % Of chemical pure potassium carbonate or sodium carbonate does not make significant change in electrolyte density. In the battery injecting a mixed electrolyte, the liquid level reaches the specified height, charging the current of the battery rated capacity 1/20, when the single battery voltage reaches 2.4V, turn the current to continue to charge, until sufficient, then then Discharge, charging, so repeated until the capacity returns to 80% rated capacity. Charging has not need to pour out the electrolyte in the battery, and adjust the electrolyte density and height according to the specified.
4. Prevention of battery pool vulcanization, correct storage battery. The battery that is not used is wet storage, and the battery should be fully charged, the density reaches 1.285, and the liquid level is added to normal, and the sealing of each monochrome plugged in the air hole after placing in the indoor dark place. The storage time should not exceed 6 months, and the electrolyte density and battery capacity should be performed regularly, such as below 25%, should be supplemented in time. For long-term storage, dry storage method should be used, with distilled water to completely discharge with a 20H discharge rate, pour the electrolytic solution, rinse with distilled water to no acidity in the water, go down the water droplets, dry after drying After the storage, it is strictly charged according to the requirements of the new battery or the repaired battery, and then put into use. Use the battery to use the battery to be in the state of sufficient electricity, the winter discharge does not exceed 25%, the summer discharge does not exceed 50%, the battery is in In the car, there is often a short supply of charging (especially short-distance transport vehicles and venue driving training) should supplement the battery according to the needs of the battery (generally at least once), timely addition of distilled water (can not use river water and well water, etc. ), Make the electrolyte liquid surface are not too low. However, for the above implementation steps, there must be professional battery forklift battery manufacturers or dealers, otherwise there is a risk.
