MARXON Group 49 H8 L5 Start and Stop Car Battery 12v 95AH 900CCA AGM BCI49 Maintenance Free Automotive Replacement Batteries

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.

Great battery, powerful, fit exactly like it claimed. I just bought 3 more batteries from this company for the rest of my vehicles. I saved $600 by purchasing these batteries compared to the total price of 4 batteries from my local auto parts store, 👍👍👍👍

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!

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_2The 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.

Perfect fit. Arrived fully charged and functional. Highly recommend this battery for stop-start engines. Just measure your existing battery before ordering.

Good price, quick shipping.

Works great. Fit perfectly in my 19 Ranger. I did charge it up on a maintainer before I installed and it took about 3 hours at 2 amps. So not low but not high either. Very happy would buy again. Quality is excellent!!
