    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.

Got my new battery installed in my generator. Ready for power outages again.
No packing or protection in box for battery. Shipped from Amazon. Notice corner of battery dented in. Hopefully no damage to battery internals.
I have been pleased with the performance of the mighty max batteries! I fully recommend them!

Great battery and price for generator!
