Using the H6 size in a 2021 Rav4 regular engine with stop/start. 3 months in and this has been a good battery. It cost less than buying from the well known big box and I didn't have to do the core deposit and take the used one back in. Plus it is the same CCA. I was not sure that an AGM could be used with this model year of the Rav4, but checking forums online, they seem to have put higher voltage alternators when the stop/start was added and the battery charges fine. Power is good. Instant starts when I push the start button. Though I haven't had it during the winter time and the coldest it will get is sometimes into the 30's at night where I live. I expect this will last a long time.

So far so good. Fixed my modern Volvo and it's quite the upgrade (note if you're installing in a Volvo S90 T6, it is a little larger than the stock battery but it still fits in the tray and the strap that holds it down still functions meaning it's safe.

So far so good. My struck starts with ease. For the price it’s really good. Highly recommend. AGM automotive batteries are very expensive. This one it’s affordable.

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.

I was a bit concerned to get a battery shipped to me, but the price was great. The price for this was as good as a standard mid-grade lead acid battery. It arrived well packaged with a heavy cardboard cover and foam cushioning that fit the battery from all sides. The battery had terminal covers. I used a trickle charger to get this up to full before installation. At 3amps this took about 18 hours. Installation went well, everything fit as it should. This met every quality standard I was looking for in a battery. The car started right up and I've had no problems with it. It's been about 4 days, with multiple starts each day- no concerns. For tech, CCA, and price, you really can't beat this battery!

This fit my OEM 2.5 Yr old battery tray and the battery sleeve as well. I got out the battery charger as the battery as receiver was around 60% charge. I charged on 8amps, so not to stress the battery. I didn't have to reset anything in our 23 Nissan Rouge SL, which was a very nice surprise. Since the install last month I recharged the battery, because it was at 80%, there is constant drain on batteries with newer all computer controled vehicles, when shut off and parked. We are retired and don't drive it every day, so it sits alot. I chose this battery based on reviews, warranty and price. I could have tried to get the OEM battery replaced, but wasn't worth the battle, the dealer said it was fine. It wasn't, it wouldn't hold a charge enough so sensor errors wouldn't pop up most every trip, the load test looked OK, but my load tester was for older batterys and older vechiels, that weren't all computer controlled. So far totally satisfied. I didn't give it 5 stars, will wait for a while to see how well it holds up to the parked power drain.

Thank you for the great customer service! Placed my order and and the seller messaged me to verify my battery size and verified it themselves as well to ensure they sent me the correct size. Popped the battery in and car started up just fine!! Great battery and great customer service. It shipped within 2 days of placing the order and arrived 4 days earlier than expected.
