I have had this battery in a car for almost a year with no issues. Still starts the car strong and keeps it's charge. Price is good for a battery this size

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.

Needed to replace the auxiliary battery of my 2023 Mitsubishi Outlander PHEV. The dealer would have charged me 450 to 500 $. This battery perfectly fits, including the drain hose. So far it works without any problems. Delivery was even faster as expected. The old battery was a Hankook 50ah with unknown chemistry, I assume standard flooded, so the new AGM probably delivers better deep discharge protection.

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.

Correct battery for 2022 Ford Maverick Hybrid truck. My old battery was almost 4 years old and still seemed to be fine but many people in online groups complain about the truck going into sleep or deep sleep mode with the original battery because the truck is always connected to the internet and you app on your phone and so there is always a small draw and when voltage gets too low it stops that so the truck will still start. Most state an AGM battery is a cure for that. I did not have that problem other than a few times it went into sleep mode (not deep sleep) but I figured at four years it was safe to replace. I gave the old battery to a neighbor who has been using it for a few months now in an older Ford Ranger and still working. This Marxon seems to be a good battery and hopefully works as well in the long run as the original did for me.

Compré esta batería con la intención de usar un producto confiable, pero lamentablemente no cumplió con mis expectativas. Intenté hacer la devolución dentro del tiempo correspondiente, sin embargo el vendedor no aceptó el retorno porque yo debía asumir el costo del envío. El problema es que el valor del envío era demasiado alto y hacía que la devolución no fuera viable económicamente. Considero que debería existir una solución más justa para el cliente cuando el costo de retorno supera el valor razonable del producto. Mi experiencia con el servicio postventa no fue satisfactoria y por eso no recomendaría esta compra.
