    • 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

    • Do not waste money and be stranded like me
Style: Group 35
If zero stars were available, that would be the right rating. Do not get tempted to save money and be stranded with no car for work or be able to pick up your kids. 1) Car would not start one morning after 4 months with battery. Had it jumped roadside (1.5 hour wait) and drove it for 30 minutes. Parked to drop off kids. It would not start again. Jumped it again with roadside (1 hr wait) and drove to shop. Uber to work. Shop tested, battery will not hold charge. Rent car to pick up kids and get to work until this is figured out. 2) There is no 'warranty' from Mighty Max. Just offer to replace after you have tested. Run that scenario: battery is dead and won't charge. They want you to have print out from retailer so, get it jumped to drive it to retailer. They say, this is used/refurbished battery. Stickers don't match. Only read out test they can give is Charge and Retest because the thing is dead./zero charge. Car won't start to drive home. Retailer won't let you leave it in lot. Get it jumped to drive home. Send results to Mighty Max. They say: please charge and test again. No. Car won't start again. Can't drive it. Mighty Max just says, we will send replacement no refund. Who wants this again?. Terrible con. Don't buy. My out of pocket for saving $100 = $250. Mighty Max should be ashamed. ... show more

    • Great auxiliary battery
Style: AUX14
We have a Chrysler Pacifica with an auxiliary battery. It crapped out and needed to be replaced. The dead battery was draining the main one and making starting the van somewhat of a gamble. I checked some YouTube clips and ordered this battery. It took about 30 minutes in total to replace the old battery and things were back to normal instantly. I can't speak to longevity as I just did the replacement yesterday, but so far it is working great. ... show more

    • Works great with Generac
Style: Group 26R
My Generac generator is 5 years old and the battery was failing. I purchased this as a replacement based on recommendation from a friend. Fits great, runs great. If you are looking for a lower priced battery replacement, this is a very good option.

    • 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

    • Good battery and price, but too tall
Style: Group 24
For a battery that is indicated as a replacement for my vehicle, it did fit, but is about an inch taller than stock. I was able to secure the battery hold down strap with a zip tie instead of the stock bolt. The plastic beauty cover over that area of the engine compartment doesn't sit properly, but for the price, this battery is a powerful replacement for the stock one. I don't spend time admiring my car's engine compartment, so I can live with the zip tie and the lifted plastic beauty cover. If the battery can't be secured with a zip tie, your car has serious suspension problems. I would definitely buy this battery again. I shopped around a lot, and this was the best deal. There's nothing better than ordering a car battery from Amazon and having it delivered to your door instead of dealing with the hassle of the auto parts store and their rediculous prices. ... show more

This Mighty Max battery was overnighted through Amazon, delivered on time with extra care. The driver knocked on the door to let me know it had arrived, I had a Legend Battey that was bought in January of 2024 didn’t even last 3 years! This battery came charged and ready to go, drop in hook battery cables up ready to go! It has a 3 year warranty and even an option to extend the warranty! How great is that? Looks to be made of quality materials just as advertised! ... show more
