Perfect for what I needed. My auto stop indicator went away as soon as I replaced the battery. Watched an online video about battery installation, and it helped with suggestions on using the posts from the previous battery to help with connection.

So far the battery started my truck at -20F but you will need a battery wrap to protect from the cold. If your in the southern US no need for the wrap. The battery fit perfectly in the battery try of my truck. I will continue to buy Mighty Max Batteries for all my car battery needs.

Ordered a group 35 battery to replace my OEM Mazda 6 battery. While my Mazda battery was testing as fine, I had severe sluggish starts, and lack of power during acceleration. This MightyMax battery fixed both problems. Mazda cars with i-eLoop electronics are very sensitive to batteries that have begun to age, but still test fine. Also, It was a breeze to install.

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...

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!

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.
