    I used this battery to replace a dead one in an APC UPS-550 that I found at Goodwill. It works perfectly. The connectors are the .250 that you need (I saw people complaining on other batteries that had .125 connectors). So far no issues. I will update my review if anything unexpected occurs.

    It puts out without input. Johnny 5 would struggle without input but not the Mighty Max.

    Silly me. I thought when I bought his 2 would come because that is what is needed. It was only one. So if you get this, make sure if you need 2 get the pair. They seem to work fine.

MightyMax for my home network UPS to keep us online!
Everything was as expected. Work perfectly for our kids motorbike
Perfect fit and great price. Highly recommended!
Best value to getting a better battery life and more life to you kids ride on.
For under $30 you get a new battery that lasts longer per charge and it all took about 5m to install.
Great packaging
Great product last all day on my fish finder
Ordered from Amazon, received in a timely manner considering the Postal strike in Canada.
Will be using in a portable amplifier. Fit in the amp and charged it up. Will add to the review when I have used it.
Picture of the amp installed in. Exactly the proper size to fit the space.
Great battery at a great price. Have used mighty max in the past on some of my other equipment.
