    • Absolute Beast of an AGM Battery! Cranks Instantly Every Time!
Style: Group 35
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. ... show more

    • Great Battery for the Price
Style: Group 48
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. ... show more

    • Horrible product, even worse customer service
Style: Group 48
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. ... show more

    • Great battery at a great price!!! 😀
Style: Group 35
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!!! 😀 ... show more

    • Strong Specs for People Running a Higher-Demand Electrical Setup
Style: Group 31
A Group 31 AGM battery is appealing because it gives you more capacity and strong starting performance, which matters a lot if the vehicle has added accessories, audio, lighting, or other electrical demand. On paper, this looks like a strong value if you want solid battery specs without jumping straight to very high-priced options. Good fit for people who need more than a basic replacement battery. Pros: ✅ Strong capacity and CCA specs ✅ Good for higher electrical demand setups ✅ AGM style is appealing for many builds ✅ Nice value compared to some premium brands Cons: ⚠️ Battery fitment and tray compatibility matter ⚠️ Real-world value depends on use case and charging setup Overall, this looks like a strong battery option for the right application. ... show more

    • Buyer Beware!!! Go to Auto Parts Store!!!
Style: Group 47
The battey failed in less than THREE months so beware of this battery and the customer service you will receive... I was told by Amazon that it has a ONE year manufactures warranty and to contact the company who sold it through Amazon... I contacted the company with the phone number provided by Amazon and was told from this company that I need to jump thru so many hurdles to prove that the battery was indeed defective... They even are nice enough to send you a link to explain all the hurdles you need to go thru... It's not enough that the dead battery left us stranded and not even a concern that this had happened to us from the seller. Finally after giving in to the seller and not wanting to jump thru all the hurdles that they place in front of you because it would just take to much time and effort... I believe they want so many things from you so that you do just give up on trying to get a return at no cost for their defective battery... So do yourself a favor and just go to an auto store and pay a little bit more because if the battery goes bad this soon they replace it with no problem at these stores... Also to prove this battery is bad they want you to use one of these auto part stores to use their tester to show that the battery is no good anyway and they also want the auto sotre to provide you with documentation LOL... You may also be told as I was that you are responsible for shipping cost to return the defective battery to them. So you don't save anything if a problem arises with this battery... I hope this helps with your decision to purchase this battery because it should have ZERO stars... ... show more
