MM-H5 Start and Stop Car BCI Group Size 47 12V 60 AH, 100RC, 680 CCA Rechargeable AGM Car Battery

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.

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!

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...

Put this in my wifes volvo that has that stop start feature (which of course is deactivated) yet is still needs 2 batteries to not kick a code. One is used for all the electrical bs and the main battery in the back is used for starting. If this small aux battery under the hood isnt working properly or is dead it puts a strain on the main battery in the back of the car. This was a little talller and has more cranking amps than the original volvo battery and took a little altering of the battery cover but it is a great battery , no codes now and easy starts. Much less than OEM battery as well.

Bought as a replacement for my Generac Guardian 14kw home generator. "26R" fits properly, hooked up and generator cranks just fine (though honestly not appreciably faster than the old lead acid battery). Fired up today no problem in ~10*F weather, though.

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

Arrived fully charged. Perfect fit in my Subaru Outback. Easy to install and the car started right up! Original Subaru battery only lasted 3 years hopefully Mighty Max lasts alot longer! Thanks Mighty Max

Intacto no era la medida es todo

La batterie est vendue comme neuve mais sa capacité de charge est de 73 % , je suis déçue! J’espère que l’a prochaine en remplacement aura toute sa capacité comme une vraie neuve!

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.

Great product heavy battery
