    This fits my 12v 35AH gel cell perfectly. I added Powerwerx meters and connectors for a powerbox to feed my telescope and accessories. 2 Powerwerx connectors: 1st is dedicated to CGEM mount, 2nd is for imaging devices through a ASIAIR pro. Center gauge shows total current and battery voltage, left gauge includes a USB power jack to power my iPad with display of charging current and voltage. Sometimes I prefer to roll my own.

    This is a very well-made product with a lid that fits good unlike other products I’ve seen that have gigantic lids. Very sturdy. It works perfect for my motorcycle battery for winter storage.

    I use this on my kayak for my trolling motor battery. Fits a 35ah Mightymax perfectly and lets me stow it under the seat of my Bonafide RS117, which I could not do with my prior box.

    How do you review a battery box? The battery fit and it did what it was supposed to do.

My battery in my old scooter died. I ordered these replacement batteries. I received them today and it's charging just fine. Thanks!

Very good quality battery! I got a great deal on Amazon. No issues with delivery. Easy install. Highly recommend their batteries. Might have to keep them in mind when I change out my garage battery 😀

Nice set of replacement batteries for my CyberPower 1500AVR unit. Plugged right in just like OEM and fired up at 86%. They’ll do!

Ordered the battery for my four wheeler and didn't take long to arrive to my house. Only complaint I have is the postal service crammed the battery into my mailbox and had to work to get it free from inside.

Previous battery lasted 4 years. So I repurchased again. Protective plastic covers for terminals were off And original Mighty Max packaging seemed to be previously opened. After initial installation in UPS item appears to be working.
