    This is my second Mighty Max battery that have purchased for my 1500 Goldwing. I have been using the first one for about four years, still working great. When I saw the sale ad, I wanted to get another one as a backup. The free delivery was a little slow, but not their problem.
    I highly recommend these battery’s.

    Fit perfectly in wife’s 1986 Yamaha Virago. The price was right and it was delivered promptly. It’s only been installed for about a month so longevity is yet to be determined.

    This is a replaced after 4 years on my motorcycle. Seems to have the punch to turn over my Vulcan 1500.

    Easy to install (depends on your bike). Plenty of power. Have had rain for almost a week and when it dried up outside, bike started right away! As for now, I can’t speak too much about the longevity because I just installed it about a month ago.

    This is a great battery for my lawn tractor. It’s a sealed battery and comes fully charged. It has more power than any other battery I’ve seen in this size. It really makes a difference in how quickly it starts the 16 HP motor in my tractor. And it’s a great price! It’s too soon to tell how long it will last, but so far I’m impressed.

    Quality sealed battery for motorcycle. As expected, high end battery.

    Installed yesterday. It would turn over. the biike, but not fast enough to start. I put it on charger overnight. Even though voltage read 13.5 V, it would not turn over the starter. I jumped with a mobile jumper and the bike started just fine. This batter,y, at least this one, was junk.

    New to air-cooled

    I was skeptical because of the price and off-brand. They want $125 locally. I just thought, hey, if it gets me through the rest of the year, good enough. I can buy a more expensive one in the spring. No big deal. It works great after sitting idle all winter. I ride fairly often. Maybe 2× or so a week. It hasn’t let me down. I doubt it will in the near future. When it finally does, I will buy another.

    Fits my 1999 Gold Wing perfectly and a great match for the Compufire alternator. This battery supply the power needed to start every time, stands up to long rides and temps in the 90’s and higher. The heat zone in which lesser batteries fail quickly. I well gladly buy this battery again.

    I have bought these before and they worked great. I just got this; but it is working great so far. I expect this to be as good as my previous ones.

    Fit my Goldwing perfectly, bike started with battery right out of the box. Battery has plastic inserts in terminals to hold mounting nut in place— Way easier than the one it replaced!

    Came charged and well packaged. Fit perfectly in battery holder and was much better than the previous battery which has the filler caps. No maintenance is ideal just keep it charged all the time for the best performance (of course). Great value, other lower quality batteries were more expensive so this choice was a no brainer.

    Great battery so far and fits perfect. I have only had it a month so far, but in AZ it is riding season, so we shall see how long she lasts. So far performing strong.

    Have no idea why would want me to rate Thickness and Warmth on a motorcycle battery. This company provides superior batteries at great prices. I’ve bought quite a few now – always satisfied…

    It’s a battery. It’s new. It works. Hope it lasts longer than the last one I bought. Had purchased a gel Mighty Max battery thinking it might be better than an acid type and I didn’t even get a year out of it.
