First, I am reviewing the H5 (Group 47 size) battery. The form is practically identical to the other H5 batteries I have used in my 2013 Hyundai Elantra GT. The fit was excellent. Second, after receiving the battery, and installing it, I put a diagnostic meter on it. At that time, the reading was 38%. However, after a couple of twenty, or so, minute excursions, the battery is now reading at 100%. Lastly, the cost was 2/3 the price of the best quote I could get locally, and now I have my old core which I can redeem for store credit at my local auto parts store. The only unknown, for now, is the battery's life expectancy. The battery which it replaced lasted three days short of six years. Like the Marxon, it had a 3 year warranty, but was 650 CCA as opposed to 660 CCA. If this battery has a similar life span, it is an outstanding value. Also worth noting: the original delivery date was predicted to be almost two weeks from the date of purchase, but it arrived in less than a week.
