    fit perfectly just what I needed

    Don Eichler –

    Had to ask for a return. Batteries are over a 1/2 inch taller than advertised and would not fit my mobility chair. I have had mighty max before and was pleased.

  3. Rated 3 out of 5

    Truman Hensley –

    Very heavy for size seems well constructed

    Dave Lang –

    The very small 6mm terminal connections are a problem for RV use. The connections are the same size as a motorcycle. Otherwise these seem like good AGM batteries. I will update as to how they are holding up.

    Nancy Iverson –

    Needed 2 heavy duty amp hour batteries for my RV. Pit a larger size and turned this one to get 185 amp hours. Should work great and also has depth for solar charger set up.

    I have a little 14′ inflatable boat with an electric trolling motor. This powers that. And it does a great job. Even after hours on the water, I’ve still got 1/2 a charge or more on the meter. I was worried about the posts being internal based on the photos and some reviews on here, but the battery comes with little screw in posts to make them more like the pop up posts you’re used to on a battery like this. One thing of note is that the battery is surprisingly heavy for its size. Like the battery weighs more than my actual boat. Carrying it from the car to the water is bit of a chore. Must be the gel in the battery that makes it extra heavy. Who knows, but the thing does its job of providing power.

    I use this battery to power my trolling motor which is a 42 lb. thrust. I am pleased with the performance so far. I am able to troll for several hours.

    I use it for a trolling motor on a Kayak. The lighter weight is perfect for a kayak user like me. This is my 2nd one. The first one lasted 5 years. This is my battery of choice.

    Great addition to solar 20 volt tool battery charging station.

It was delivered fast. Good product.
Frank Scarano
Was an excellent fit for my fios wall box. Inexpensive too! Was dealing with a dead battery for years with beeping every few minutes. This fixed it right up and now will keep internet when the power goes out.

This saved my life... Well not my life but... well the battery on my new predator 3500 generator was dead!! I got it on a super duper sale but I didn't open the box for 6 months, when I did I discovered a bad battery 😟. I called them and they wanted double the price I paid for Amazon to deliver it the SAME DAY!! They didn't even carry the battery in their store 🤬. I put it in and just like that, I can run my mobile Italian ice business again! 😆 Thank you mighty max and Amazon for getting me together!!

Great battery at a great price. Work really well.

This might look like a mess of wires, but it's really the backbone of my home's network and more. Everything important to our home security and connectivity relies on steady power that I have on a battery backup.

I just purchased a replacement battery for my UPS and it's a Mighty Max Battery that is working behind the scenes here. This was almost half of the cost of the OEM battery, and it was a perfect fit for the unit.
