Mighty Max Battery MM-H6 Start and Stop Car BCI Group Size 48 12V 70 AH, 120RC, 760 CCA Rechargeable AGM Car Battery

If you are looking for a rock-solid, high-performance AGM battery that won't break the bank, the Mighty Max MM-G35 is an absolute home run. The difference in starting power is night and day. Here is why this Group 35 battery easily earns a full 5-star rating: 🚀 Key Highlights & Performance Flawless Start-Stop Performance: This battery handles start-stop cycles effortlessly. AGM (Absorbent Glass Mat) technology is a must-have for modern, high-draw vehicles, and this unit manages the constant on-and-off cycling without breaking a sweat. Massive Cranking Power: With 650 CCA (Cold Cranking Amps), the engine turns over instantly and aggressively, even on freezing cold mornings. There is zero hesitation or sluggishness. Impressive Reserve & Capacity: The 55Ah rating and 100RC (Reserve Capacity) mean you have plenty of reliable power to run accessories, dash cams, and electronics without worrying about draining your main power supply. Built Like a Tank: True to premium AGM design, it is completely sealed, spill-proof, and highly resistant to intense engine vibration. You can install it and completely forget about maintenance, venting issues, or terminal corrosion. 🛠️ Fit and Installation The BCI Group Size 35 form factor is a precise, standard fit. The terminals are cleanly molded, solid, and accept heavy-duty vehicle clamps perfectly. It has a reassuring weight to it, which is a great indicator of the quality and density of the internal lead plates.

The cost of this MM-G35 battery was a big factor in my decision to purchase it, as it costs literally half of what some of the big name brands do! I am a great fan of AGM batteries. I’ve used the “yellow top” brand in my heavily modified 2002 Silverado one ton diesel truck since it was just a year old. My first set (Diesel engines require two batteries) lasted an unbelievable 14 years! AGM batteries typically have a much greater service life than lead-acid batteries. I also use an AGM battery in my heavily modified 2005 Jeep TJ. So when my wife’s 2021 Subaru Ascent Touring was ready to a new battery, it was a no-brainer decision that I was going to purchase another AGM battery. The battery was delivered within 36 hours of my purchasing it with zero damage to neither the battery, nor even to the outer packaging. It also arrived fully charged and ready to install. The fit was perfect and installation took less than 10 minutes. I’m very happy to be done with my wife’s old lead acid battery and I hope she has many, many years of trouble free service from her new Mighty-Max battery. 😀 Also, simply by registering your purchase, via the included QR code, the manufacturer’s warranty will be extended an additional three months, 👍 I will also be adding a photo of the installed battery to this review very soon, as the warranty period will be increased by an additional three months by the manufacturer, just for doing so. 👍 I’m very happy with this purchase and I highly recommend this AGM battery!!! 😀

Absolutely TERRIBLE product. The first one I ordered arrived dead and wouldn't take a charge at all, not even a single volt. I guessed it might have been damaged in shipping. Amazon customer service was great though. They missed an immediate refund and didn't require I return it, and they advised the easiest solution was to simply order again. I did so and the second one arrived and worked fine... For a while. The second one lasted just over a year and was outside of Amazons warranty window so I was told I would need to contact MightyMax directly. They first made me jump through a bunch of hoops including taking it to Autozone to get a scan and a print out of the result (which was "bad" of course, as I had already told them). Every time I emailed them to answer their question or jump through another hoop, it took them 24 to 48 hours to reply, so by the time they agreed it was indeed bad and under warranty, a week had gone by and I needed my car working so I just bought one locally. I told MightyMax I would prefer a refund at this point but they said it was out of the question and advised they would send a replacement (that I don't need at this point). Well, here it is 2 weeks later and still nothing from them. No battery, no email, nothing. Yesterday I sent an email asking for an update and here we are 24 hours later and still nothing. DONT BUY THIS BATTERY! DONT DEAL WITH THIS COMPANY! YOUVE BEEN WARNED.

Bought this to replace the battery in my Jeep and so far it has been great. It arrived well packaged, fit like it was supposed to, and had plenty of power right out of the box. The Jeep starts strong and I haven't had any issues with it. Considering what some of the name brand AGM batteries cost, this was a much better deal. So far I'm very happy with it and would buy it again.

Easy install. Accurate description for my 2006 Subaru Outback 2.5 lt. Well built. Great warranty.

exactly as described, I have purchased several batteries from Mighty Max for my motorcycles and my car. they have a great product, and you can't beat the price. great customer service as well.

The battery is an AGM battery priced cheaper than any other AGM battery you can find. I was skeptical since it's a random company "Mighty Max" but it started my Honda Odyssey right up. The problem is the size of the battery. It is taller than most 24f batteries. Luckily it fit under my Airbox duct, but I had to buy longer J-Bolts for the battery hold down clamp as the OEM Jbolts were to short. Other than that, it seems like it will be a fine battery. Only time will tell if it lasts as long as other... more common AGM batteries.

My last battery for my 2014 Forester was installed 3/19 a Duracell battery that just failed. I suppose 7 years isn't bad. This battery fit perfectly and has 12.6V out of the box that arrived upside down. No leaks so the battery seal is good. We will see how long this battery lasts. If not very long I will update. It is supposed to have a 36 month warranty in addition to the Amazon refund within a year policy.

Excelente opción muy bien empacada mi auto arranco a la primera y marco 14.3 de voltaje se ve muy bien construida la compraría de nuevo sin pensarlo dos veces

The product fit my Hyundai 2017 Accent perfectly. The battery works perfectly, even in cold weather and no longer have to use the jump-starter!

The battery works and fit very well in 2008 BMW M6 with V10 engine.

Excelente, funciona muy bien, solo tardo un poco más de lo que estaba programado
