(See BU-804: How to Prolong Lead Acid Batteries) Charging a lead acid battery is simple, but the correct voltage limits must be observed.Choosing a low voltage limit shelters the battery, but this produces poor performance and causes a buildup of sulfation on the negative plate.

Adding carbon on the negative electrode reduces this problem but this lowers the specific energy. ) Lead acid has a moderate life span, but it is not subject to memory as nickel-based systems are, and the charge retention is best among rechargeable batteries.A full discharge causes strain and each discharge/charge cycle permanently robs the battery of a small amount of capacity.This loss is small while the battery is in good operating condition, but the fading increases once the performance drops to half the nominal capacity.Learn about the differences within the lead acid family and find out what the cons and pros are.Invented by the French physician Gaston Planté in 1859, lead acid was the first rechargeable battery for commercial use.These batteries are often known as “lead-antimony” and “lead­calcium.” Adding antimony and tin improves deep cycling but this increases water consumption and escalates the need to equalize.Calcium reduces self-discharge, but the positive lead-calcium plate has the side effect of growing due to grid oxidation when being over-charged.The recombination occurs at a moderate pressure of 0.14 bar (2psi).The valve serves as a safety vent if the gas buildup rises.Despite its advanced age, the lead chemistry continues to be in wide use today.There are good reasons for its popularity; lead acid is dependable and inexpensive on a cost-per-watt base.
