    Great battery but the terminals were different than the original but luckily my wires were just long enough to make it work You can’t beat it for the price

    Nice product at a great price. Since it is sealed it was delivered through the mail. Remember that most mail (USPS) is slower than UPS. I knew that it was a little big for my generator a ,4300E but I was able to jam it in on end and just get the cover on the generator. One end of the cover bows out a little. Very happy with this purchase. I needed something that would last long and not discharge quick between use. This has greater AH than old wet cells that fit the generator plus now I have no acid dripping to corrode that bottom case.

    The product was shipped on time and worked well. I had one problem, the lead connections were opposite of the original which meant I had to do some swapping around with my cables.

Love mighty max batteries
Roger Smith
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.

Susan Blankenship
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.
