    I’m not certain why people say it doesn’t work for the WiFi power pet door. I can’t speak for any models other than that one. Yes, you have to bend the prongs out straight, and you need to push pretty hard to get it to snap in. But the battery compartment door closes and it works just fine.

    I had to bend the metal plug in bits (can’t think of what you call them) so they were straight, but it was easy and the battery fit perfectly in the receptacle for my power pet doors. I have two of these doors so I came back to get a second battery because both of the older batteries stopped working. I didn’t realize it until the power went out and there was no battery back up. The price was right too. The older batteries were twice as much.

    These batteries will work with a little effort. I had to bend the prongs back and flatten them, as much as possible. They are difficult to get into the slots, but eventually I got them to work. After all this, the cover for the batteries will not fit, so you just see the battery.

    Far better than the OEM battery. Rather than last for hours these last for days!

    Great product. The original battery that came with the door wasn’t holding a charge After three years, this was inexpensive and works great. It holds a charge for a long time (~4-7 days so far) and such a low cost I bought two so I can have one on the charger ready to go as back up.

Arrived in perfect condition
2011 Yamaha Raptor 700R battery, started right up. Has a 1 year warranty. Great deal.
Love mighty max batteries
Arrived well packaged. No information as to original warranty coverage and term, but lots of solicitations to extend the warranty coverage for a whole amazing 90 days - Wow, such product confidence! At least it’s not made in China, but is Thailand any better for quality manufacturing? We’ll see.

Arrived next day and sas very easy to install. They also offer free 3 warrany extension.
I ordered this MightyMax battery through Amazon. The Ad states it works in my GE Simon XT house alarm.
I received my battery from Amazon on March 9, 2026. The box was a little squashed but the battery was packaged well and it it fine. I installed it and finally my gate opener is working properly. I purchased 2 batteries before this and had to return them because they were the wrong battery. This one is working great.
Looks the part, I am charging it fully before install on my jet ski.
These batteries arrived in great shape with the handle on top so you can carry it screw so you can hook them up very professional looking better about them from Home Depot
