What are the main factors that cause damage to lead-acid batteries?
China is the largest lead-acid batteries supplier . Lead-acid batteries have a history of more than 200 years and are a widely used power source. It has the advantages of easy material availability, low price, large discharge capacity and high reliability. At present, the market share is very high, and it cannot be completely replaced in the future for a long time. The design life of lead-acid batteries is about 5 years, but in actual use, the capacity is gradually reduced in 6~12 months, and the actual service life is only about one year. After analyzing a large number of failed batteries, the failure conditions were as follows: vulcanization, water loss, unbalanced grouping, softening, short circuit, and open circuit. Among them, "vulcanization" (lead sulphate crystal) accounts for more than 90% of the failed battery, which causes the battery capacity to drop and becomes the main reason for the end of battery life. The charging and disch...
