Battery Basics!!
Lead-acid batteries, invented in 1859 by Gaston Plante, are the oldest type of rechargeable battery. Sulfation is one of the problems that kill batteries. Lead sulftate is created when a battery is discharged. Then, when charged, in theory, the lead sulfate changes back to its component materials; lead, lead dioxide, and sulfuric acid. However as batteries age, hard lead-sulfates form into crystals on the surface of the electrolode plates. Heat build-up from sulfation and corrosion destroys the battery's grid. It is the grid that holds the material that produces the chemical reaction that stores and releases electricity. So getting rid of sulfation is the key. As a matter of fact, early batteries were built in a wooden box and allowed folks to remove plates to clean. Things have not changed except you can't easily remove the plates. That's what led us to find a way to de-sulfate and lower resistance of the electrolyte.
