Re: Is There An Electrician In The House?
Old batteries typically did last years longer.
Many years ago the lead plates in batteries were a lot thicker and were solid virgin lead. You could often flush out an old battery and then put in new acid to double it's life.
Several of the poplular modern car batteries available today typically use more recycled contaminated remelt lead that is then formed into lead plates that looks more like a waffle. This waffle plate design is done because there is more surface area for the acid and they can use less lead. New batteries are now lighter in weight because the shells are now plastic with a thinner wall and using less lead. Years of cost cutting and increases in efficiency is now giving you the throw away 6 volt battery of today.
