Love the Boost!!! I got newer batteries for my grandchildren and painted this black for my boys

It was delivered fast. Good product.

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.

Shipped as it should have been. Received in good condition.

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.
