    Good batteries delivered and packaged properly. Your UPS will love you again. EVERYTHING from your TV to your Stereo and all computers should be on a UPS. Clean power saves your disk drives and keeps your computer memory functioning correctly – but you need to have working batteries not just to keep the power on for a short time when the power fails but to augment the sine wave when the glitch dips into the waveform and removes energy. Today everything has a computer in it, and designing realtime electronics for industrial environments (like the average home these days) is a lost art that will die with this generation of computer engineers.Electronics from China is always questionable. Filters are often removed in production to save money. The technology of dealing with dirty power is not well understood by most youngsters. If you can’t afford to replace your computer, TV etc or you need long term reliable performance change the battery every 3 years and test its performance at least once a year.

    I bought this for my Craftsman Diehard portable power 1150. One of the reasons I bought the Diehard unit was because the battery could be replaced. After about four years I needed to replace the original battery so I ordered the Sears Diehard battery. It lasted less than two years and never would take a 100% charge so I decided to see if there were any equivalent batteries for it when I came across this one and decided to give it a try. Before I installed it I topped off the charge with my Battery Tender charger and it took 100% charge. In a couple of days it will be a month since I installed it so it will be time to top off the charge again. I believe this battery will work out a lot better than the last one.

    I replaced a battery in a portable jump starter/air compressor. The mighty Max battery fit perfectly and came fully charged and ready to go to work. The Mighty Max company couldn’t have been better to work with.

Mighty Max Battery
Based on 3474 reviews
Arrived quickly. Even got a sticker with it.
Solid looking battery, came well packaged. Have used their battery before for my lawnmower and now looking forward to see how it lasts in my snowmobile.
I can't believe it less than 48hrs since I ordered from Walmart and it's in the machine. What more can I say except great price.
Thanks Larry
Item as described and perfect fit and arrived on time
Battery arrived in a good shape package strait to my door steps
Arrived just in time to power my generator here in the cold Maine winters. Excellent service!
Arrived quickly from WALMART.COM. Perfect size and proper placement in my generator. Installation was easy. Generator fired right up. Battery came fully charged.
New battery. Ready for cold weather!
So far these Might Max batteries are good but it’s only the first day and they were on charge for 12 hrs. I’ll have to come back and do an update at some point in time. Ordered them on Amazon and got them the next day. I was encouraged by Mighty Max to make this google review and post pictures to extend my warranty for 3 months but there is no way to post pictures 🤣🤣🤣 It’s been a few months and I was able to go back and edit, so here is a video I made, the rest of the photos I have deleted. Batteries are still going strong. Update 12-11-2025
They arrived within 2 days of ordering them packaging was really good I haven't put them in my MX350 yet I hit them with my multi meter fresh out of the box and got 12.4v on both batteries so that is good
