Lead-acid batteries are used in automobiles, golf carts, fork-lifts, electric cars and motorcycles. They are recycled by grinding them open, neutralizing the sulfuric acid, and separating the polymers from the lead and copper. In the US, 97 percent of the lead from car batteries is recycled - which is the highest recycling rate for any commodity.
IUoU battery charging is a three-stage charging procedure for lead-acid batteries. A lead-acid battery's nominal voltage is 2.2 V for each cell. For a single cell, the voltage can range from 1.8 V loaded at full discharge, to 2.10 V in an open circuit at full charge.
As a battery is discharged the density of lead sulfate in solution increases. In common designs, it reaches a critical density when discharged to about 75% depth of discharge, or below. [ 2 ] For instance, a 12V battery with a 100 ampere hour (Ah) capacity will reach this density when 25 Ah (300 Wh) or more have been drawn from the battery.
The main benefit of the lead–acid battery is its low cost; its main drawbacks are large size and weight for a given capacity and voltage. Lead–acid batteries should never be discharged to below 20% of their capacity, [67] because internal resistance will cause heat and damage when they are recharged. Deep-cycle lead–acid systems often use ...
The KiBaM battery model [3] describes the recovery effect for lead-acid batteries and is also a good approximation to the observed effects in Li-ion batteries. [1] [4] In some batteries, the gains from the recovery life can extend battery life by up to 45% by alternating discharging and inactive periods rather than constantly discharging. [5]

Lead may be found in food when food is grown in soil that is high in lead, airborne lead contaminates the crops, animals eat lead in their diet, or lead enters the food either from what it was stored or cooked in. [111] Ingestion of lead paint and batteries is also a route of exposure for livestock, which can subsequently affect humans. [112]
