    After almost a year of going back and forth with product support from the manufacturer of my electric-start mower, I replaced the battery–and bingo, it started with the first push of the button. It remains to be seen how long it will last, but so far, I’m thrilled.

    It’s every bit as good as the original battery.

    Quick delivery, good price. Used to replace the battery on a car Jump Starter Vector 300A, same capacity (9AH) but smaller terminal tabs. Same physical size. Had to modify it by drilling holes on the Center of the tabs for 8-32 screws and bend the tabs straight up to attached to the big gauge cables in the jump starter.

    I chose this battery for the dimensions, so that it would be a direct replacement. Well, it’s about 3 1/2 inches high, not 3.94 inches. So it doesn’t fit correctly and I have to come up with something to take up the extra space. Other than that, it seems to be a good battery. Dimensions are very important to some people, and it’s a simple thing to get right.

    It was a close replacement as it was the same length and width but was a little bit shorter in height.

    Battery arrived ahead of estimated delivery time.It is a perfect fit for CyperPower 1500va UPS. Original battery was down to 18% capacity and provided less than 10 minutes of UPS power. The new one came fully charged and CyberPower console application estimated 58 minutes of runtime during power outage test.

Cool looking battery., will be placing in a Pontoon Boat soon. 👍
Received the replacement ML4-6 battery for my Coleman lantern and it was an exact match. I’m very happy with the battery and it works as it should. Update, ordered another mighty max battery. This time it was for my battery backup. Exact for and extremely easy to swap out. For $20 i got my $80 backup working again. Thank you mighty max battery another satisfier customer with an excellent retutation, i highly recommend.
Excellent Product and Seller!!!
I placed it as you can see from the old to the new on my EverStart Jumper as you can see in the pics it fit perfectly and I gave it a 24 hour initial charge on my house outlet with a thick orange cable and as I tried it it worked perfectly in all functions, I woulkd give it a 100% Excellent Recommendation!
I had an old harbor freight 3 in 1 auto battery jumper that no longer would hold a charge. This ML 18-12 MIGHTY MAX REPLACEMENT BATTERY, fits exactly as original and is holding a stat of charge greater than 13 volts after first time charge. The photo is the old battery. I've already installed the he MIGHTY MAX and don't want to open again.
Packaging was very good.
Let's see how long it lasts.
Works like original
They are what I ordered and they came sooner than I thought then was told to me
New home rough but comfortable
Excited to try a GEL battery and hoping for extended Life in Florida. Engine starter spins like brand new.
Great Battery!
Great price! Heavy duty!
