How Does Lead-Acid Batteries Work?

Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.

Battery storage, shelf life, self-discharge, and expiration

Batteries freeze more easily when kept in a discharged state. As noted, freezing temperatures can adversely alter the cell''s molecular structure. At the other extreme, heat hastens the self-discharge rate and can create stress. Lead acid batteries. Charge a lead acid battery before storing. Lead acid batteries can be stored for up to 2 years.

Characteristics of Lead Acid Batteries

The final impact on battery charging relates to the temperature of the battery. Although the capacity of a lead acid battery is reduced at low temperature operation, high temperature operation increases the aging rate of the battery.
