    Just installed this battery on my new, slightly USED, low hours Generator. It fired the generator up quickly. I will edit this review in about 9 months and will report on how this battery holds up in the Florida heat. So far, so good.

  5. Rated 5 out of 5

    Very intriguing

    I have always had good luck with Mighty Max batteries. Some have lasted 6 years so that’s a great return on the dollar spent. Depending on the battery and application, the cost can be as little as $3 per year. Not bad at all. They are excellent batteries.

    I figured it would be cheaper to replace the battery in my 15 year old Xantrex powerpack 400 plus than buy a new unit. Decided to upgrade to the gel battery over the standard since it did not cost that much more and is a deep cycle battery. I was very disappointed to see the terminals were inboard on the battery I received not outboard like the stock photo everybody has. It was immensely difficult to connect the cables in the booster box since the cables were a fixed length. I had to dismantle the booster box and carefully bend everything so I could connect the battery and get the cover back on.

Great choice for my ktm
I was very pleased with the way you packed the 2 batteries I purchased off of you, both being Mighty Max, one for my 1999 Honda Forman 450s atv & my 2008 Suzuki 250 motorbike. Thank you kindly & may GOD bless you abundantly...💗🙏

Might max 6.5 v. perfect fit for ‘23 HAWK DLX EFI
I wished these would last more than one year.
Was desperately in need for my generator replacement battery and started my search. Not only did I find the highest rated battery with 5K+ reviews, but I also found it for a fraction of the big box store prices. Thanks to MightyMax I received it overnight!
Quality packaging. Comes with terminal hardware. Tested with voltage meter to make sure it was fully charged out of box. Happy with this purchase!
Works great
