Quality ACDelco battery
ACDelco batteries have always been reliable. You get what you pay for. Quality product. I was very impressed with how this battery was packaged for shipping. After testing for load and charge, fully charged and load rated higher than labeled. AGM batteries may cost a little more, okay more than a little, but worth the peace of mind. If you have a vehicle that isn't used regularly like a classic car or truck it's more forgiving. Do your research for the advantages of a AGM battery.

Poor manufacturing and failure under load
battery is heavy at 49.5 lbs. Not easy installation, also battery had manufacturing defect. Installed battery started up car several times. Next day when out to start the car and nothing, the battery just clicked as if no charge, investigation revealed a wobbly or loose negative ground within the battery. To return had to put it in its own packaging and take to UPS, no other choice. Poor value for the money, and luckily I was home and not somewhere when this battery failed.

Super fast shipping and well packaged
All good. OEM packaging inside a Amazon box. Perfect. Just a hint for anyone replacing their auxiliary battery, replace the main battery at the same time. And if replacing your main battery, replace this ESS battery also. Double hit, I understand but one will destroy or greatly shorten the life of the other if not replaced as a pair. Lessons learned.

GM / AC Delco says go to Amazon for warranty - Amazon says go to GM AC / Delco for warranty!
GM refuses to warranty this product beyond 1-year because it was purchased through Amazon! Junk! Stay away from this seller!

The Battery's Fine, but "Make Sure this Fits" is Wrong
The battery’s fine. It met my expectations and does what it’s supposed to do so it gets 3 stars. I’m writing this review because of the inaccuracy in Amazon’s “Make Sure this Fits”. It said that this battery would not fit my 1976 Pontiac Firebird / Trans Am. But it did fit. The vehicle takes a group 78 battery and this battery fit perfectly.
