This battery is a great replacement for AGM OEM batteries. Size is correct for group 47 H5 battery. Functional and came with 55% charge. I fully charged before use. Heavy duty durable battery. Awesome value for the money. Easy to replace. includes some instruction and warranty card.

Great battery! Exact match to size and description. Fit the car perfectly and fired it right up. Excited to have the extra CCA’s for my cold winters coming, as the AGM of Mighty Max has better CCA’s than the one issued with the car. All that at a much more reasonable price! Well worth it!

I’ve been running the Mighty Max battery in my 2006 Mercedes S430 for a few weeks now, and I honestly couldn’t be happier. I was a little hesitant at first because it’s priced lower than some of the big-name options, but it’s held up exceptionally well, even in eventfull weather and after sitting for a few days. Cranks strong every time. What really impressed me was the fitment. It dropped right into place with no modifications needed, which can be tricky with older luxury cars. Voltage stays consistent, and I haven’t noticed any electrical hiccups or drain issues since the swap. For the price and performance, I definitely recommend if you're looking for a reliable, budget-friendly battery without cutting corners.

DANGEROUSLY UNRELIABLE – Stranded Me in the Desert After 60 Days! Rating: 1.0 out of 5 stars Product: Mighty Max Battery MM-H7 Start and Stop Car BCI Group Size 94R I purchased this Mighty Max MM-H7 battery expecting reliable performance, especially given the "Start and Stop" designation which implies durability. My expectations were not just unmet; they were shattered in a way that put me in actual jeopardy. This battery failed completely after just 60 days of use. Not 6 months, not 6 years, but 60 days. The failure was sudden and total, turning my vehicle into a heavy, immobile paperweight without warning. The worst part? It happened while I was driving through a remote stretch of highway in the desert. Because of this catastrophic failure, I was left stranded in intense heat for over four agonizing hours waiting for a tow truck to arrive. A car battery is a critical component, and a failure of this magnitude, this quickly, is unacceptable and borders on dangerous when you rely on it for safety. I would strongly advise any potential buyer to look elsewhere. The short lifespan, coupled with the severe inconvenience and stress it caused, makes this one of the worst automotive purchases I have ever made. Do not risk your safety or your time on this product. Save yourself the headache and the tow bill.

It works great. I had to replace a auxiliary battery in my 2014 Chevrolet Malibu LS. It fits perfectly. The Amazon delivery driver delivered it with care and it was on time. The battery is great . I recycled my old battery at a auto parts store I will buy this battery again. Perfect fit and the k you Amazon for a good price for the auxiliary battery.

Packaging and battery look great. Waiting to install but for the price it seems to be a great deal. I got this for my 2021 Nissan Kicks

Bought as a replacement battery for my Challenger. Fits in the battery spot no issue. Tested with a couple different battery testers after being fully charged and shows well over 850CCA. It has been in the car for 6 months, in what can best be described as a Sunday driver/Show car. It has held a charge, and always cranked the modded 5.7L motor without fail. I also have a 4,000 watt sound system, and run a second battery to help with that. With this battery, there has been no light dimming, and no worries about leaving me stranded.
