When cells are used beyond their sustained and/or burst current ratings, a small amount of irreversible damage happens every time.

You can mix 1 pound of Aluminum sulfate with 1 gallon of boiling distilled water. Blend this mixture until it is clear. Afterwards, fill the cells with this solution and charge the battery.
