It turns out that Sealed Lead Acid (SLA) batteries are not infact all that well sealed. You can perform maintenance on them much the same as you would any other wet cell battery, such as car batteries. In this instructable I will show you how to do this. What you will need: -Distilled water -Small straight screwdriver -superglue or hot glue
By design sealed lead acid batteries are, by their very nature, sealed. This means that if they have been damaged by ovecharging and have dried out then it is problematic to restore them. Ironically it is possible to do this damage in the first place because they aren't completelysealed. There is a rubber cap on top of each cell.
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.
In the highly charged state, a lead acid battery will revert to lead and sulphuric acid, only becoming lead sulphate when discharged. It's quite difficult to photograph the inside of the cells but the photo below is good enough to see that there is no liquid above the plates.
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.
When charging a lead acid battery, sulfuric acid reacts with lead in the positive plates to produce lead sulfate and hydrogen ions. Simultaneously, lead in the negative plates reacts with hydrogen ions to form lead sulfate and release electrons. This chemical reaction generates electrical energy used to power devices.
