    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.

Love mighty max batteries

Arrived well packaged. No information as to original warranty coverage and term, but lots of solicitations to extend the warranty coverage for a whole amazing 90 days - Wow, such product confidence! At least it’s not made in China, but is Thailand any better for quality manufacturing? We’ll see.

I received my battery from Amazon on March 9, 2026. The box was a little squashed but the battery was packaged well and it it fine. I installed it and finally my gate opener is working properly. I purchased 2 batteries before this and had to return them because they were the wrong battery. This one is working great.
