WhatsAppLead-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.

WhatsAppLead-acid batteries rely primarily on lead and sulfuric acid to function and are one of the oldest batteries in existence. At its heart, the battery contains two types of plates: a lead dioxide (PbO2) plate, which serves as the positive plate, and a pure lead (Pb) plate, which acts as the negative plate.
WhatsAppThe common design of lead–acid battery has ''flat plates'', which are prepared by coating and processing the active-material on lead or lead–alloy current-collectors; see Section 3.4.1. One alternative form of positive plate has the active-material contained in tubes, each fitted with a coaxial current-collector; see Section 3.4.2 .
WhatsAppThis recommended practice is limited to maintenance, test schedules and testing procedures that can be used to optimize the life and performance of valve regulated lead-acid (VRLA) batteries for stationary applications. It also provides guidance to determine when batteries should be replaced. An amendment< IEEE Std 1888a is available for this standard.
