A bit more info on the picture I posted in the above post.

Sometimes a garage mechanic will say----Trouble with your battery Sir ???---It's probably because it is sulphated up inside.---

Avoid this mechanic as he obviously doesn't know sulphate forms and vanishes when battery is in use. If it didn't no electricity would come out of your battery at all.---

If you follow the coloured lines in that picture it will tell you exactly what goes on inside your battery every day.
