Most lead acid battery additives contain EDTA, or ethalene diamine tetra acetic acid has always been known to dissolve the lead sulfate layer on the plates. There are, however, two downsides to this: EDTA usually comes in powder form, or as a solution. With manufacturers tending to favour sealed maintenance-free type batteries, there is no chance to introduce EDTA to the battery in the first place. EDTA works by forming a complex compound with the lead sulfate layer on the plates. While this removes the insulating layer, the active material that had formed lead sulfate will not be reconverted once the battery is charged.
In principle, the insulating layer of lead sulfate is removed, but active material is sacrificed in the process.
EDTA reacts with the lead sulfate to form the complex compound above. The plates are cleaned, but active material is not returned to the battery.
Complex compound formed by breaking the lead sulfate bond.
Battery life is extended temporarily with the removal of the lead sulfate crystals and increase of reaction surface area, but the lifespan of the battery cannot be maximized unlike using our Desul
