    I probably don’t treat my batteries well over the winter but this time I made an effort to use my bike every so often. The WAY this battery died was strange too. It just went from fine to nothing which O’Reilly told me was a dead cell. Fortunately my bike died in the parking lot of said O’Reilly’s. For what it’s worth I ended up paying almost double for a battery from them and I had to setup the acid, etc. myself so I’ll be fair and give it 3 stars (rounding up from 2.5…

    Brand New battery, charged ready to install out the box. This is my 5th time buying this brand battery (various sizes) and am convinced these batteries are just as good if not better than large store brands that cost double or more.

    The battery has provided reliable starting power for my Kymco scooter. I get the feeling that it’s stronger than the last couple batteries I’ve had. My only gripe is that it’s slightly bigger than previous batteries–so big that it won’t fit all the way into the battery compartment. However, even though I have to leave the lid off the battery compartment, I can still close the seat, so this hasn’t been a problem. On balance, I’m happy with this purchase.

    Bought this battery as a replacement for my wife’s UTV. It’s predecessor cost 3X what this one did and only lasted 2 years. This type of battery seems to be relatively short-lived. Even if this one lasts a single year, I will still be way ahead on cost. It directly replaced the old battery with no problems. Would likely buy another one when this one fails.

    Battery came charged although I topped if off with a trickle charger before installing. It came with new nuts and bolts, fit into place on my bike, and fired it right up. Unfortunately the bike will be sitting over winter so I don’t have much usage on the battery yet. So far it seems like a decent product and the price was great. Also it shipped quickly.

    The battery was the correct size and came in great condition. However, the top posts (cages) where not straight. They weren’t bent just attached at a an angle from the factory. In most cases this wouldn’t be an issue, but I was putting this in a Honda 600 VLX motorcycle. The battery on these things is in the worst possible place in side the frame and access to the posts is very limited. I had a very difficult time trying to get the screws to screw into the lugs in the cage at the angle the they were at. So not very impressed with that. And the battery was supposed to come with at least a partial charge, but mine was completely dead. Not a problem, just not what was advertised.

    This is a great little battery. I needed a battery for my DuroMax 4400 genertater. I did not want to spend $80. So I gave this one a try. it is bigger than the original but that is ok, I just took some wire and secured it to the area the battery sits in. was fully charged, and there was not leaking in the shipping box. It was about 1/2 wider and 1/4 to 1/2 taller than the original battery… All is good again.

    Great value for the money. Much cheaper than an equivalent battery from Sears, though I haven’t had it long enough to know how long it will ultimately last. Works great in my scooter and it is totally sealed against any acid leakage. My previous battery was a Sears Diehard which came with the acid in a separate bottle that the buyer then needs to pour into the battery. The MightyMax battery does not need this as it’s more of a gel cell type battery and never needs to be filled or refilled. It also came partially charged. Fit wise, it is a perfect replacement for the equivalent Yuasa or Sears Diehard.Update 3/2/2017: Battery hasn’t missed a beat. Still working like the day I installed it. Outstanding value.

    I purchased this battery to replace a significantly larger battery in my 400 cc ATV. I was skeptical that it would work because of the size but for less than 33% the cost of my previous battery, it was worth a try. It works great, so far. Longevity and cold weather performance is yet to be determined. I’ll provide updates with time.
