I purchased 2 of the ML35-12 - 12V 35AH batteries for a motorized Jazzy Pride Elite Select wheelchair. This has been sitting on my parents farm unused for 15 years. The batteries were easy to install and it fired right up after charging. I think this wheelchair has another good 20 years or so of life left in it as long as I keep replacing it with Mighty Max batteries.
I have to give some of the easy install credit to Claude AI, he walked me through every step of the way. However, what I want to note is Claude is who recommended I go with the Mighty Max. AI truly is getting wiser :)
The batteries came very well packaged and protected from the blade I used to open the package. I truly appreciate when companies do that.
I'm going to surprise mom with this tomorrow so I'll get some shots of her zipping around and add them to this original post.

Delivered today ordered yesterday from Amazon. Packaging in great shape. Installed on my Ghost Control gate. Working well. Tried to attach a photo of it in place. Would not upload.
