A Damaged Battery cannot be revived but those that are sulphated certainly can. I would be skeptical of additives but I have seen incredible results with the Swedish "Macbat" Machine, Ok I am biased as we have one ourselves but they work.

The Battery manufacturers would love you to believe otherwise but then how unbiased are they.

Imagine if Engine Manufacturers could convince everyone that engines cannot have Service or Oil Changes and you just throw them away when they stop !!!! How lovely that would be for them ----- now in a way the battery folk have gotten away with something similar.

Never throw away a sulphated battery without putting it on a Macbat Machine or something similar.
