Thought id try this brand for My 2020 Toyota Corolla. Six months along now no problems, great reserve power. Much cheaper than auto parts store, costco, and AAA. I missed an Amazon deal while it was in my cart and the seller RESTORED it for me,WOW! Just make sure to get correct size.

This battery has been awesome so far. It was a perfect fit in both our 2018 and 2019 Dodge Grand Caravan, and installation was easy with no issues at all. It cranks strong and has held up excellent over time. It worked so well that I ended up buying a second one for our other Caravan too. Definitely a solid purchase.

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.

I bought this three months ago with some trepidation because of the unknown brand and a price so much lower than any other AGM battery I could find. It's performing flawlessly. And by performing, I don't just mean that it starts the car reliably. I have been into cars, electricity, and electronics for 65 years, so I know how to measure and monitor. There is a simple method to known what the percentage of charge a battery has by reading the voltage after a full charge and then getting rid of the "surface charge." Let it sit overnight, or turn the headlights on for a minute. You then read the voltage and compare it to tables that are available on the intertubes. Conventional lead acid and AGM's have different charts. This is a good tool, for batteries of any age. For this new AGM, my concern was that for an AGM to reach 100% capacity, it requires a bit higher charging voltage than the conventional lead acid. However, using the method described above, this charges to 97-98% just fine. I made an experiment possibly of interest to fellow auto nerds. I discharged the battery by leaving the lights on for a few hours until it dropped to 11V. The starter relay just clattered. I put a charger on and got it up to 11.2V, and that 3.7L V6 just spun right up. (A not well know fact is that conventional, no maintenance batteries lose a heck of a lot of their capacity if you let it run down EVEN ONCE! You buy an expensive battery and just leave the lights on or something, and there goes half of your investment. However, an AGM is inherently a deep cycle battery, which is the reason I went AGM.) Speaking of chargers, I bought the following unit and have been beyond impressed. Not only can it charge to AGM specs, but it does an amazing reversal of aging on older batteries. I have rejuvenated so-so batteries to literally good as new, per the tests above. www.amazon.com/dp/B0D7Q2SXFQ?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2 The warranty is also very good, although as we all know, in this day and age, sometimes they are hard to activate if needed. We shall (hopefully not) see.

Fit as expected. I would buy again as long as it lives over 3 years. The seller did a good job of communicating and verifying fit. My battery tester only showed 80% estimated life when I tested it but it is a low end tester. Testing after driving a week showed 60% life. Alternator is putting out over 13 volts. As I said, probably the cheap tester. Start stop is working again. It stopped when the old battery started going out.

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.

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.
