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.

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.
