  1. Dyon –

    Good choice for a back-up battery for HAM radio go Box

  2. A.C. –

    works great right now, only time will tell

  3. Rogbaby1 –

    I like that it is a Gel battery at a great price

  4. Craig Hissong –

    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. 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.

  6. rparker559 –

    perfect replacement Battery

  7. danny mccraw –

  8. Akinola Ojeleye –

    This battery was bought for my generator. It is doing a great job.

  9. P Rife –

    Exact fit and so far great performance, installed in Black Max 7kw generator. Thanks

  10. Doug –

    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.

  11. Web Customer –

  12. Customer –

Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.

As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
