    Good to have, if you still have a few old acid batteries around. Would have given it five stars if it came with instructions. I had to look at a few you-tubes to see how to put it together.

    Product arrived in perfect condition. It does exactly what it is supposed to. I also use it to refill those hard to reach batteries. I am very happy and would order it again.

    Die Leseratte –

    The company sent me the acid tester. Unfortunately, the plastic tube was taped shut. When cleaning the tube became blind and thus the whole tester unusable. I wrote to the company and recommended to change their packaging method and at the same time complained about the tester. I was sent a new tester free of charge and didn’t even have to send the old one back. This is really a first class service. I can only recommend the company.

    nice quality tester for the money !! Now I dont have to rely on an auto repair shop to tell me if my battery has any cells that are weak… Of course it can only be used on batteries that have removable caps to access the cells… Great for do-it-yourselfers !!!!

    Just what was needed. The outer cylinder is not breakable glass, but plastic.

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.

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.
