    This battery is generic, so it behaves like any other battery off this type. It did arrive on time.It was very easy to install, and seems to be performing its role, backing up my telephone line.Thanks for the prompt delivery.

    That was actually a very easy and cost efficient decision to replace the Verizon battery by myself, and not go through Verizon.

    Replaced the battery in my Verizon phone/internet box. worked great. The terminals were a diffrent size than the original battery. Pliers fixed that problem. This is the second one I’ve purchased. Last about 3 years. Price is good and drop the old one off at the gray box store down the street for recycling

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
