    I got 8 of these for an old APC Smart-UPS device. After replacing all 8 batteries (some were about 8 years old and were pretty bad), the replace battery led didn’t go away. The battery status led was showing all good/charged, so I was suspecting the issue was with the APC device (it’s a really old device). Turns out I was supposed to reset the status in order to remove the warning. So, if you’re buying these batteries to use with a APC Smart-UPS, you may need to press the test button for a couple of seconds to reset the batteries status. Once I did that, the replace battery led went off as of the occasional beep too.

    After reading reviews, I pulled the trigger. This battery came pre-charged, and very well packed. The terminals had protective plastic sleeves on them to prevent any short circuits during shipping. My old Security System battery kept giving low power readings to the alarm panel. I contacted my Alarm company, and they advised me to replace the original battery. The most difficult part was disconnecting the wire terminals from the alarm system from the old battery terminals (use needle nose pliers – makes it very easy). Connected the new battery, and the alarm panel immediately showed that batter was fully charged. Very satisfied.

    This part was very economical and easy to replace. When I first replaced it the Bat signals remained on my system but after several hours it disappeared which drew me to the conclusion that it needed to be fully charged. It has been almost one month since I replaced it and I have had no problems at all, but that doesn’t say anything about its longevity.

    This is a standard sealed lead-acid battery. I am using it for my bicycle (tricycle) lighting which consists of an MR-16 LED 6-watt spot light as a headlight, and two 1-watt taillights. This battery will run the lights at full brightness for at least 3-hours. It weighs about 2 Kilograms.

Mighty Max Battery

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
