After seeing so much BS info on the battery, i will answer my own question
In 1859, the French physician Gaston Planté invented the first rechargeable battery based on lead acid, a system that is still used today......
Enough said, why try to re=invent the wheel?

 

OK, who invented the AGM battery?

 

Essentially, Gaston Plante invented the AGM.
Plante invented the lead-acid battery. In the 1970s, sealed lead acid (SLA) batteries were first produced in large numbers.

Now:
The most common SLA batteries are the gel and AGM variety. The theory of how they work goes back to Mr. Plante, therefore, he invented them. Many people are getting the idea that the AGM battery is something 'new' or 'better'. AGM batteries are not new or better, they are a bit different, sure. They have some advantages over other lead-acid batteries as well as some disadvantages. But they are not a new invention, they represent an evolution of design and manufacture of an existing product.
