VW battery

The factory original batteries are surprisingly long lived, some go ten years. But my thinking is that any battery more than four years old could go without warning. If you can not read the indicator, have it load tested and replace it if in doubt. There's a tough Winter coming so play it safe.

20 years old and still works? It's a miracle!

I agree F_O_R. I had to check my math, but yes that car is twenty years old and if that's THE original battery, it should go straight to a museum or Ripley's Believe It Or Not.
