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.

Why did you pick this product vs others?: Bought this for a Buick Lacrosse that uses stop/start technology. It has so much more power than the original battery! The old battery would not allow the car to actually stop and start the engine the way its designed. Now it works as advertised and starts the car effortlessly. Price was extremely good for a gel pack battery with this much CCA. Battery quality: Excellent. Much better than the OEM battery.

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 battery is great, fit well in my Mercedes Benz with high CCA, compare to other leading brands that cost more, O'Reilly and Autozone brands where more expensive, I recommend this brand of battery

I was searching for the ideal battery for my 2021 Toyota Corolla during the winter months. The original 12V/45 AH battery that came with the car struggled to hold a charge in cold weather and failed to start on chilly days after three years, although it performed well in milder conditions. After researching and reading customer reviews, I chose the 12V/50 AH MARXOM AGM battery, which is the correct size for my 2021 Corolla. It is more affordable than other brands and has a 36-month free replacement guarantee. When I received the battery, I found it was low on charge—only 25%—so I needed to recharge it. After fully charging it, I installed it in my car. The Group 140R H4 LN1 size fits my 2021 Corolla perfectly. I’ve noticed that the 12V/50 AH AGM battery significantly outperforms my original battery. So far, I am delighted with this product and would highly recommend it.

Ended up at Amazon becuase Walmat did not have a battery for one of the top selling cars in the world. Went to the dealer and they gave me a battery that did not fit (Diehl Toyota of Hermitage) Had to return that one. Ordered this one with much more cranking amps than the one from Toyota, cheaper with a better warranty. Arrived quickly, very well packaged and fully charged. Highly recommend this battery as a factory replacement.

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.
