Read the term and condition first, it could say warranty void if this and that(use in hot condition). Or it's not consider spoil even u can't start a car cause it can light a light bulb.

I won't waste time in looking for a better car battery as the technology already like 40 years old, if it can be easily improved, it should already be done by all human kind, it's like how to get your third leg installed.

car battery or lead acid can last many years if use in "perfect" condition, if you can relocate the car battery to somewhere else not close to the hot engine, it can last much much much longer

i copied this off google



so the "technology" you are talking about should be how to slow or insulate heat to the battery. Technically i dont care what brand its, every year about the same time, i swap the battery, i dont want to take the risk of unable to start my car when i urgently need to use it. maybe it can tahan for another few months, but i just dont want the risk, not worth it.
