    Bought in 12/2018. Worked well for home alarm system, but here I am less than 2 full years since purchased it and need to replace. Will gladly pay a bit more for longer lifespan. Will try Interstate next.

    I installed the new battery, and it was fully charged within 12 hours. I hope it lasts longer than the old expensive one.

    This battery is the second from this maker for different tools. Can’t see a bid of difference in performance that that of factory installed battery with tool was new, but BOY is there a difference in price. Saved over $70 by buying this battery ov er buying a replacement from the company that made the tool.

    I purchased this for replacing an aged APC UPS battery. I don’t know how much different the claimed 5AH is from similar products’ 4.5AH. It’s so far so good.

Excellent
Mighty Max Battery
Based on 5386 reviews
Installed on log splitter with 15 hp Raven engine. Works fine.
Arrived fast and nicely packaged
It took longer to get them from Amazon but well worth the wait
Works like a champ. Great battery replacement for my CupCadet zero turn.
Works as it should!
Look good.
It was hard to tell if I should order a U1 or U1R. Thankfully, my mower's leads were long enough either way.
upgraded RV batteries to MightyMax ML100-12 Gel 100 AH INT Terminals
Purchased this to replace my prior battery for my sump pump backup system. I don't think the original battery provided with the system was the correct type. The alarm used to trip all the time, but so far this one, which is specifically for my sump pump backup unit is working great.
Batteries came well packed and protected. These are used in a 300 pound remote control model tank. See the photos. Easy to maintain on a trickle charger and fit in the exact needed space. Thanks
