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.
A lead acid battery typically consists of several cells, each containing a positive and negative plate. These plates are submerged in an electrolyte solution, which is typically a mixture of sulfuric acid and water. The plates are made of lead, while the electrolyte is a conductive solution that allows electrons to flow between the plates.
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.
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
Try to avoid running the battery down to zero. Sometimes, lead acid batteries can suffer from irreparable damage that cannot be fixed through reconditioning. One common cause of irreparable damage is sulfation, which occurs when lead sulfate crystals build up on the battery plates over time.
As routine maintenance, you should always check the battery electrolyte levels and ensure that the battery cells are always covered. Sealed and valve-regulated lead-acid batteries are designed in such a way that the gases released from the electrolysis of water in the electrolyte, recombine back to form water. 3. Thermal Runaway
