    Bought two of these batteries as replacements for dead or dying batteries in battery jumping units from Harbor Freight. They fit perfectly and were easy to install. I hope they will last several years!

    Battery was in new condition and mostly charged. Installation into the jump starter for which it was bought, was extremely difficult, thought that had everything to do with the jumpstarter and not the battery itself. Longevity remains to be seen.

    Old jumper battery died and this one fit right in and works well. haven’t had it very long so don’t know if it will last as long as the original one, but guessing I bet it will.

    Have this battery installed to replace a failed battery in a Harbor Freight 3-in-1 portable power pack. Replaced about two months ago and is still at full charge. Original battery needed charging monthly. Will see how long this will keep charge. Very pleased so far.

    I charged the battery and the Diehard powerpack read 100% after charging for three days. I went to use it and check the charge percentage it read 80 percent. I?m charging it again to check the quality of the battery. Never had that problem before. Not sure if it is the battery or the power pack.

    Working really well. Little hard getting the wires hooked back up in the unit, but that’s no fault of the battery, just a poor design on Die Hards part. Will buy from again when needed.

Excellent
Mighty Max Battery
Based on 5578 reviews
I've been using Mighty Max batteries for years. I needed a battery for my Cub Cadet XT1 LT50 mower. The available options were all over $90. I found this MM model that fit perfectly and had more CCA, 230 vs 210. $40, Enough said.
Perfect replacement for Pride Gogo Sport scooter.
Purchased this item from Amazon in the morning and had it at 2:30 in the afternoon, same day. Straight out of the box it had 12.93 volts in it. I am on my way to install it in the ATV. I'll have to wait to see how it holds up ,but I am hoping it will do well, have had good success with other Mighty Max batteries. I love that it is a sealed battery for ease of maintenance and can't spill on the machine.
A perfect fit for my craftsman z5400 46 inch mower
Used the batteries in a man lift and it has been working perfectly so far! Thanks for a great inexpensive product!
Great price. Great availability. Only wish the nuts to attach weren’t “loose” and were tapped like oem. Just a bit awkward
This is my second time with this battery. The first one lasted 2.5 years. For the price and lifespan of the original MightyMax battery versus a Volvo dealer original, I’m extremely satisfied!
Battery was priced great and works great so far. It's only been installed in the 4 wheeler for about a week.
Good so far
The Mighty Max Battery came is a heavily insulated box, so no damage on arrival. Fit perfectly and my ATV started immediately. Thank you so much.
