CyberPower Office Power AVR 685AVR 12V 8AH Replacement Battery - Mighty Max Battery

Amazon Customer: This is a really good deal. I live in florida and we get lots of electrical storms in summer. sometimes the house electricity will go on and off for only a second or two or for less than a minute but those short bursts are enough to shut down your electrical stuff. i have the battery back up to run my TV, Modem, Router, and my surround system when the electricity goes off and on and this little guy takes care of all those short outages. I am not worried if the electricity goes off for an hour or something like that just the short ones and this is perfect for that. sooooo... the battery quit working a few days ago. i was thinking of buying another one because it had worked so good but then i thought about just replacing the battery. The cost was less than $25 so why not give it a shot. when the battery got here i took the old unit and with just removing 1 screw i had the new battery changed out in less than 1 minute! and now it works just like if i had bought a new one. Im set again for the short outages that are coming. i highly reccomend this battery to replace your old one.

Jimi: The battery fit in my Cyberpower UPS, but the spade terminals are too small. The female connectors in the UPS would not stay on at first, but I was able to crimp them down to size with pliers to make them work.

I won't be buying this brand again.

B U: It also survived against at least 3 times of ~1-day long power outages, plus a few brown outs. Fingers crossed for it to keep going. When it passes 3 years of its services, I will certainly come back and give it a 5 stars for its longevity.

a customer: The battery is advertised as a replacement battery for the Cyberpower 685AVR; I needed a replacement battery for a Cyberpower 685AVR, so I ordered one. Alas, I should have read more carefully. This battery has F1 (4.75mm) tabs, a fact which is disclosed in the product description; the 685AVR has spade terminals for F2 (6.35mm) tabs. The connectors therefore do not fit securely on to the smaller battery tabs.

The customer service people at Mighty Max Battery were very nice, and suggested I first try using tab adapters which they sent me, free of charge. Alas, these extend the tabs in such a way that it's practically impossible to get the rigid wires into the available space inside the UPS. They also seemed a little rickety.

At this point, I asked for and received without argument a full refund.

I'd give full marks for service, but this is a review of the battery, and unfortunately it did not meet my needs. If you have a device with F2 terminals, I'd skip this one. On the other hand, if F1 terminals fit your requirements, I see no reason why this battery wouldn't work for you.

thofar: I have an older Cyber Power 685AVR that quit working some months ago. I thought I was going to have to throw it out and buy something new. However, I found this replacement battery that totally solved the problem and at a fraction of the cost.
