Lead acid batteries can sometimes sustain damage that cannot be repaired through reconditioning. A common issue is sulfation, where lead sulfate crystals accumulate on the battery plates. Severe sulfation may reduce the battery's capacity beyond recovery, making replacement necessary.
Here are some tips on how to fix a sulfated battery: 1. Remove the battery from your device and clean it with a dry cloth. 2. Apply a sulfate-free battery cleaner to the battery and scrub it with a brush. 3. Reinstall the battery into your device and turn it on. 4. If the battery still doesn't work, you may need to replace it.
Steps to Recondition a Lead-Acid Battery Safety First: Wear safety goggles and gloves to protect yourself from the corrosive acid. Remove the Battery: Take the battery out of the vehicle or equipment. Open the Cells: Remove the caps from the battery cells. Some batteries have screw-in caps, while others have rubber plugs.
All lead-acid batteries suffer from sulfation. It's just chemistry. Lead-acid batteries contain lead plates and a free-flowing solution of sulphuric acid. One of the inevitable byproducts of the plates and acid coming into contact is that lead sulfate will accumulate on the lead plates of the battery.
Sulfation occurs when a battery is deprived of a full charge; it builds up and remains on battery plates. When too much sulfation occurs, it can impede the chemical-to-electrical conversion and significantly impact battery performance. When your battery has a buildup of sulfates, the following can happen:
