Make sure you have a charger that is rated for AGM battery charging. You'd be surprised how many Optima customers I ticked off telling them I can't warranty their battery (which they swore was "bad") until I charge it first.

We had a B.A. Autometer charger that was excellent at AGM batteries. Charged up, didn't see many of them come back. Not doubting "bad batch" battery and QC issues - I know they happen.

And for what it's worth, when I worked for a Dodge/Hyundai dealer - our "OEM Replacement" Mopar and Hyundai batteries were delivered on an Interstate truck. Just saying.
