    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.

Mighty Max Battery
Based on 3481 reviews
Arrived fast and in perfect condition. Plus, as you can see, it came fully charged!
Ordered online from Home Depot. Arrived in good order.
Bought a Mighty Max H6 on line, was wondering how packaging would be. When it came packaging was great. Installed battery today, -14 degrees out, car fired right up out of box, impressive.
On time and as described.
I can't believe it less than 48hrs since I ordered from Walmart and it's in the machine. What more can I say except great price.
Thanks Larry
Awesome battery. Fit perfectly
Perfect fit for replacement of OEM motorcycle battery. Very happy. Great price!
This little battery is how we power our music with our rechargeable speakers
