    Worked perfectly

  2. JW –

    Battery arrived fast. Had about an 80% charge. Charged it and waiting to be used/ installed this spring. Can’t say anything about longevity yet or cranking power.

    Bought this like 6 months ago and I’m barely writing this review. Still working strong.

  5. Hector G. –

    Best bang for your buck ! Fits 2005 R6 like a glove and awesome customer service went above and beyond to make sure everything works

  6. Michael Reeves –

    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.

  10. Richard Ades –

    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.

    Worked in my Suzuki Burgman 200. So far so good!!!

    Good product; arrived on time!

  18. MightyPen –

    Factory correct size for 2008 Suzuki Burgman AN400 model. Also I verified it is identical to the 2013 Burgman AN400 as well.

  19. Robert 7941 –

    good deal slow delivery

  20. Jonathan –

    This thing turns the motor over faster than any battery I’ve ever had in the bike and as a result, it cranks faster.

  21. Frank Drake –

    It’s great work like it’s supposed to.

  22. bushman –

    perfect fit quick shipping

  23. Bill A. –

    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.

  24. Music lover –

    Works as expected for a Suzuki Burgman 400, 2007. I couldn’t find one anywhere in town.

  25. Ben Bailey –

  29. aries –

    Great battery. I out this in my 08 zx6r. Started right up. The best part about this battery is that i didnt have to fill it with acid or charge it before installation. It was good to go!!!!

  30. J –

    Battery terminal screws are a little short… makes hooking up the Battery cable terminals tough.

  31. D. W. Lunt –

    Does exactly what I needed for a 2014 Suzuki Burgman. Fits the battery compartment perfectly. Plenty of amperage so far to get the engine to start quickly. Great price, quickly shipped, and securely packaged.

  32. Firefighter Mike –

    Absolutely best battery i have ever had for my moped.It is very strong and superbly holds its charge.

  33. New Mexican Senorita –

    Purchased this battery to replace a dead one in the motorcycle I was trying to sell. Worked fine for the short time I used it before I sold the bike. Much better deal then spending $80+ at a auto store.

  85. Web Customer –

    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.

  96. Jon Jones –

    Quick delivery with no special handling requirements. Charged quickly and maintains charge well.

  97. Rosch32 –

    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.

  98. Julius –

    Put it in a few months back, haven’t had any problems so far. Will def buy again if I need to.

  99. Patrick Pierson –

    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.

  100. Babblefish –

    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.

  101. dean eisenberg –

    fast arrival great buy

  102. Keith Seiler –

    The battery is a great value. It shipped prormpy and worked right out of the box. It was much cheaper than local sources

  103. Don –

    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.

Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.

As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
