The service life of lead-acid batteries is generally more than 5 years, but it is found that many lead-acid batteries are scrapped after 3 or 3 years of use. Improper use and the quality of the product itself will directly affect its service life. How did this happen, and who was responsible for the loss of battery life? Let's discuss it together.

There are several reasons for the scrapping of lead-acid batteries:

Reason 1:

Water loss is one of the basic reasons for the reduction of battery capacity. Water is an important component in the battery electrolytic reaction, once the battery has been charged, large current discharge, internal resistance increases, short circuit, etc., easy to generate heat and form water steam, water steam in the sealed battery box will be mostly retained, but there are very few will be lost (because of the density of the battery shell material), over time, the battery will appear water loss state.

Reason 2:

Improper use of the battery, long-term insufficient charging or battery in the semi-discharge state, excessive discharge or not timely charging after discharge, internal short circuit, electrolyte density is too high, high temperature, low liquid level to expose the plate and so on May lead to sulphate, on the plate due to recrystallization formed coarse lead sulphate crystals, the crystallization of poor conductivity, large volume, will block the plate micropores, Hindering the penetration of the electrolyte, increasing the resistance, it is not easy to reduce into irreversible lead sulfate when charging, so that the active substance in the plate to participate in the electrochemical reaction is reduced, so the capacity is greatly reduced, and even failure scrap. As long as it is the regular manufacturer according to the national standard production, within the design life, in the normal maintenance state of scrap batteries, most of them are caused by vulcanization.

Reason 3:

Lead sulfate crystals are gradually produced on the electrode plate of lead-acid battery when it stops charging and discharging. This phenomenon leads to the aging of the battery, which is manifested as: battery charging and discharging difficulties; Battery capacity decreases; The corrosion of the electrode plate is further promoted and the battery life is reduced.

Lead acid battery maintenance tips

Through the above we understand that the maintenance work of lead-acid battery is not in place, the improper use of the battery will affect the service life of the battery. Proper and timely water refill of lead-acid batteries can ensure the good operation of the batteries and prolong the service life of the batteries.
