EverStart Platinum AGM Battery, Group Size H5, 12 Volts, 640 CCA, 100 RC

One of the best AGM on the market. Bought it to replace AGM G35 that lasted 5 years, and was still fine. Only issue with the old battery wasn't related to the battery itself. I have a mazda 6 GT 2014 with i-ELOOP. Frankly, this system is useless and can give error if the battery isn't able to charge the copastor. That was was the reason, not the battery that could have gone another year, at least! WM AGM G35 is out of stock for the last few months. After some research, I found some Mazda owners used the H5. It fits very tight due to width difference, otherwise, it woks as it should. Funny enough, upon returning the old batter core, the G35 was on shelf.. Some customers complaint about the core refund at WM. It went smooth. Associate needed several steps to issue refund as gift card.
