    Bought for a Honda trx400ex works great. Figured it would need charging right out of the box so put it on trickle charge and it was fully charged right out of the box. Came with terminal hardware too! Will buy again if needed

    When looking for batteries, make yours will fit. Even though this popped up during a search, it will not fit. This is MY mistake. Just warning everyone.

    Exactly as described. Product showed up well packed and was fully charged. Buying a battery online had me worried but the price had me hooked. After running this battery for a few month with no issues I would recommend. My bike sits in the garage most of the time as the weather here sucks. It is not on a trickle charge (bike has been sitting for 6 months) starts every time.

    I have a generator that I have been cranking by hand for over two years and I was having trouble, a lot of trouble, cranking it by hand. The battery was just what I needed and the first time I cranked the generator using the battery I laughed out loud. What a relief.

    If you powering a motorcycle I recommend and agm powersports battery. Only because the motorcycle runs off the battery. Constant cycling cause it to go dead fast. But if it’s for atv or go kart etc works fine Battery Dies on my motorcycle after couple days Battery life longer on my atv

    The battery was as described, came fully charged. The screws it came with were too long and a challenge to get under the lead terminals and through the holes. I used a Philips and Needle Nose Pliers to carefully wrangle them in. I used this battery in a Buddy Scooter and it was a little taller than my case would allow, I needed to saw off a portion of the plastic cover that presses against the battery to keep it from moving – nothing to do with the battery itself – still something to consider when ordering. Even if the battery will fit in the scooter casing, your casing lid may take up a portion of that height. All ‘n’ all a good value for the battery. Let’s see how long the battery lasts!

    The connectors on the battery for the cables were too high and the screws too short. I had to pad underneath them with a piece of cardboard to raise the nut high enough for the screw to reach it. Battry was hard to install because it was slightly too tall despite being an exact swap.

    I bought this battery as a replacement for an old Honda ATV. When the battery arrived I topped off the charge on a very low current charger and then left it attached to a tender for another couple of days until I got a chance to look at it. Before installing, I checked it with a battery meter. It checked at 225CCA at 80 deg F. So I was pretty happy so far given this is a 135CCA (spec) battery. Granted, an official CCA measurement would be done at a lower temperature, but the large margin over spec looks good compared to a lot of fresh batteries I’ve measured.Installing the battery turned out to be a little more trouble than it should have been – although it’s more of a nuisance than anything else. It appears the terminals are a little larger than standard, although they can be made to work. Also the hardware (screws and nuts) are not right. Typically, when you slide the nut into the retention area of the terminal, the screw should be able to pass through the top of the terminal and reach the nut without having to lift the nut. Not the case here. The provided screws were too short even without passing the screw though the cable terminal end. I moved back to the screws and nuts that I just removed (the old screw was about a millimeter or so longer than the new screw), however the old screw couldn’t reach the old nut either (once again without I tested it without passing the screw through the cable terminal end). Furthermore, my old ATV has formed terminals on the end of the battery cables to prevent them from spinning (basically the far end of the terminal end is bent over), however the cable terminal ends would not sit flush on the battery terminals with the screws inserted and tightened due to the form on the end. The formed ends sat on top of the terminal. So clearly the battery terminals are oversized (but still usable for me) as compared to prior battery brands that I’ve used.The battery did fit into the compartment space, although the retention bar was a little more bowed than usual when tightened downI’m giving it 4 stars because the CCA check was considerably above spec for this battery, which outweighed the inconvenience of installing it. The old Honda started fine with this battery, so we will see how long it lasts.

    This is a wonderful battery compared to the batteries I have been using. The others didn’t last long at all. This battery and the charger that came with it work well together. The price was great and delivery was very fast. My bike starts everyday now without a hitch.

    It’s exactly what I needed, I kept buying the ones from pep boys and they would go dead if I didn’t start my quad every few days… with this battery it lasts weeks without a start.. I’m very pleased. .price was great too.. I will definitely recommend… oh and got it in great timing too.

Mighty Max Battery

Hope the battery works as good as it looks
Great deal on two of these batteries. Packaged extremely well. Put one on my generator and it started right up.
Works great installed easy and come pre charge.
Product came as described. Install was easy. Battery came 100% charged. No vibration tape included, that was the only drawback.
Very satisfying with my new battery!
Battery works as advertised. Powers my air compressor just fine.
This battery was well described and make my son's power wheel jeep run better than new.this is the ML15-12v 15ah SLA . Rechargeable battery.
Nice replacement from Amazon for my Liebert UPS.
Westinghouse has junk batteries in their generators and I had to buy a new one and prove to them that the battery passed a load test before they would replace the starter in the generator that was bad as well. So far very happy with the Mighty max
These batteries amazing! This is my original battery. It is being replaced after 15 + years!!
