Antigravity Battery

Has anyone in the group tried one of these ?

They appear to be VERY expensive but I can see major advantages.

I would be very interest any research that has been done along these lines.

Since, I only get to drive my 55 once a month when in California for a week each month

it sits for long periods of time. I have been lucky so far with NO problems but with the

High Demands I can see the day coming. This trip I'm going to outfit it with a "Solar Tender".

But this Battery really has peaked my interest.

I did find this thread but it only deals with "jump-starters".

That was me talking about their jump pack, very good. I don't think I would use a lithium ion for a main car battery though. They have a limited lifespan. I am running an AGM battery right now and I really like them. I had an Optima last over 10 years and it was great. I put a Champion AGM in my SLK last year and it is doing well.
