What chemical use for desulfation in battery?

Desulfation in lead-acid batteries is often achieved using chemicals such as sodium sulfate or a solution containing sodium bicarbonate. These compounds help convert lead sulfate crystals back into active materials, improving battery performance. Additionally, some desulfation processes may utilize specialized desulfation agents or additives designed to facilitate the removal of sulfate buildup. Regular maintenance and proper charging techniques can also help prevent sulfation in the first place.
