How do you recondition a lead acid battery?

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.

How do you charge a lead acid battery?

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.

What is a lead acid battery?

Lead-acid batteries are wet cell batteries. Each cell contains two slightly different lead plates, and the plates sit in electrolyte fluid, which contains sulfuric acid. If the electrolyte level gets too low, the lead plates are exposed and sulfation — the deposit of a hard lead-sulfate compound on the lead electrodes of the battery — occurs.

What happens when a lead acid battery is charged?

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.

Can a lead acid battery be drained?

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).

How do you rebuild a 12 volt battery?

Wear protective gloves and goggles before you rebuild the cell structure of your 12- volt battery.

Car Battery Reconditioning (A How-To for LFA Batteries)

The lead acid battery generates electrical energy through a chemical reaction between its electrolyte fluid (consisting of sulfuric acid and water) and lead plates. Each time a battery discharges, lead sulfate crystals form on the battery plates. When the lead acid battery is recharged, the lead sulfate disperses. However, not all of it goes away.
