How do you restore the power in a old motorcycle battary so that it works like a new one?

Question

I understand that a build up occurs on the lead plates of a battrry and if you can remove the build up then the battry will work just like a new one for another few years.

Answer 1

When a battery gets so old that it can no longer hold a charge, then it is time to retire it. There is no cure for old age as far as batteries are concearned.

Answer 2

You can flush it out with distilled water and refill it with new battery acid but it is a temporary fix at best.

Answer 3

Flush it out with baken soda and water.once it is clean add new acid and charge it up
