    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.

Using it in a large surge protector to protect electronics in a CNC milling machine. In a power outage, the battery maintains current for machine memory.

Put it in my generator and worked perfectly. No issues other than the box arrived very much covered in dust from the delivery vehicle I assume.
James Gates
Put it on and it fired right up the first time in months. No jump needed.

Ordered the ML5-12 from Amazon.ca to replace my garage door-opener battery and arrived within 2 days. Well packaged, already had over 12V charge. Exactly the same size as the Chamberlain Original battery I was replacing (Model #4228). Fit perfectly in the opener battery compartment and worked right away. For around a third of the cost I’ll definitely be ordering the Sam again in a few years when it’s time to renew.
