How to Fix Damaged Battery Plates?

[Randall]

For mildly sulfated plates, you can use a soft steel wire brush to remove the sulfation layer from the surface and continue using them. You can place appropriately thick wooden boards between the plates and slowly clamp them with a bench vise to straighten them, then continue using them. If only the welded tabs of the plates are broken, you can make a welding frame with an iron sheet, weld them back, and continue using them.
