Battery sulfation is the build-up of lead sulfate crystals within your lead acid battery''s surface and pores, which can cause the battery to stop working. The good news is that most damage made through battery sulfation is reversible, and the problem itself can easily be prevented if you know the signs to watch out for.
To recondition a lead acid battery, you need to remove the lead sulfate buildup from the plates and restore the electrolyte solution. This process involves cleaning the plates, adding distilled water and sulfuric acid to the electrolyte, and charging the battery to its full capacity.
1. Construction of sealed lead acid batteries Positive plate: Pasting the lead paste onto the grid, and transforming the paste with curing and formation processes to lead dioxide active material. The grid is made of Pb-Ca alloy, and the lead paste is a mixture of lead oxide and sulfuric acid.
Remove the battery from the vehicle to charge it. Charging a fully discharged lead acid battery off of a car alternator can result in an overcharge and may damage the battery. Use a crescent wrench to loosen the battery cables. Always wear safety goggles and protective gloves when working with lead acid batteries, even the sealed type.
When a lead acid battery is charged, the sulfuric acid in the electrolyte reacts with the lead in the positive plates to form lead sulfate and hydrogen ions. At the same time, the lead in the negative plates reacts with the hydrogen ions in the electrolyte to form lead sulfate and electrons.
To restore the capacity of a lead-acid battery that is not holding a charge, you can use a desulfator device. This device works by sending high-frequency pulses of energy through the battery, which break down the lead sulfate crystals that have built up on the battery plates.
Low maintenance or “sealed” lead acid batteries are widely used in cars and other vehicles like ATVs and golf carts. However, these batteries can be completely drained on occasion and must be recharged. The process is similar to that used for the older types of lead acid batteries (those that have removable caps on top for each battery cell).
