Why is acid stratification the principal case of lead-acid batteries

Stratified acid promotes increased internal resistance, lower conductivity and accelerated sulfation on the lower part of the plates, reducing the battery''s dynamic charge acceptance. This means

Why is acid stratification the principal case of lead-acid batteries

Stratified acid promotes increased internal resistance, lower conductivity and accelerated sulfation on the lower part of the plates, reducing the battery''s dynamic charge acceptance. This means a sulphated battery will only accept a surface charge, resulting in a false positive state of charge readings to vehicle computers and battery testers.

(PDF) Sulfation in lead–acid batteries

Whenever sulfuric acid is the limiting reagent, the electrolyte in a lead–acid battery approaches that of pure water when the 118 H.A. Catherino et al. / Journal of Power Sources 129 (2004) 113–120 battery is fully discharged.

What Causes Failure In Lead Acid Battery?

In flooded lead-acid batteries, contamination can result from accumulated dirt on top of the battery and when the battery is being watered. Watering the battery with tap water has a serious consequence on the battery.

Factors Affecting The Life of Lead acid Batteries--JYC Battery

The life of lead-acid batteries is extended with the increase in temperature. Between 10℃ and 35℃, every 1℃ increase, about 5-6 cycles, between 35℃ and 45℃, every 1℃ increase can extend the life of more than 25 cycles; above 50℃, the life of the battery is reduced due to the loss of capacity of the negative electrode

Reasons For The Decrease Of Battery Capacity

The main reasons for capacity decline are as follows: 1. Plate vulcanization. That is to say, the white coarse grain lead sulfate gradually formed on the surface of the electrode plate is hard and difficult to dissolve in the electrolyte, and it is not easy to reduce with the electrolyte when charging, thus reducing the active substances. In addition, the coarse-grained lead sulfate
