Lead-acid batteries lose the ability to accept a charge when discharged for too long due to sulfation, the crystallization of lead sulfate. They generate electricity through a double sulfate chemical reaction. Lead and lead dioxide, the active materials on the battery''s plates, react with sulfuric acid in the electrolyte to form lead sulfate. The lead sulfate first forms in a finely divided, amorphous state and easily reverts to lead, lead dioxide, and sulfuric acid when the battery rech…
Get PriceValve regulated lead acid (VRLA) batteries are similar in concept to sealed lead acid (SLA) batteries except that the valves are expected to release some hydrogen near full charge. SLA or VRLA batteries typically have additional design features such as the use of gelled electrolytes and the use of lead calcium plates to keep the evolution of hydrogen gas to …

Get PriceTesting the health of a lead-acid battery is an important step in ensuring that it is functioning properly. There are several ways to test the health of a lead-acid battery, and each method has its own advantages and disadvantages. In this article, I will discuss some of the most common methods for testing the health of a lead-acid battery.
Get PriceThe essential reactions at the heart of the lead–acid cell have not altered during the century and a half since the system was conceived. As the applications for which lead–acid batteries have been employed have become progressively more demanding in terms of energy stored, power to be supplied and service-life, a series of life-limiting …
Get PriceA low-density reading shows that the battery has lost some of its electrolyte solution and must be replenished. Sealed lead-acid batteries eliminate the ability and need to perform specific gravity tests; however, the requirement to test the battery''s state of charge still applies even if you are unable to perform a specific gravity …

Get PriceHow Gel & AGM batteries are similar. Both AGM and Gel batteries are "recombinant" batteries – this means that the oxygen which is normally produced on the positive plates of all lead-acid batteries (technically, both Gel and AGM batteries are classified as lead-acid batteries) is absorbed by the negative plates.
Get PriceFlooded batteries also need to be watered from time to time to remain in good working condition. In sealed lead-acid batteries (SLA), the electrolyte, or battery acid, is either absorbed in a plate separator or formed into a gel. Because they do not have to be watered and are spill-proof, they are considered low maintenance or maintenance-free. ...
