Customer Ratings & Reviews

I have used this brand before. They are excellent for keep your cable modems, TVs, Computers, Dish network, and phone working properly when you have momentary outages. No annoying resets!

Had my first power outage the other day and power stayed on for computer and network. Power came back on after 5 minutes so I can't tell you how long the backup battery will last. Highly recommended.

Reasonably priced backup battery with multiple outlets, many surge protected. Better to be safe than sorry...

I had this battery before. I think it protects my computer against power surges and back up in case power goes out. I had to purchase again because the power battery had its use.

I bought this for peace of mind in case the power fluctuates or power failure. I've seen it worked several times when the power fluctuated and all the peripherals connected to it were not damaged. Glad i purchased this!

The Cyber Power battery backup is excellent! We have had one before and it works great when the power goes out so you don't loose what you are doing or damage your computer.

Had the previous version which lasted many years. Bought 2 more when it died. Great for Florida where power goes out often for a few seconds. Back up my computer and wifi router and cable box.

It's not the most expensive battery backup, but it works. I had an earlier version that went caput after 5 years or so o. The issue with these is that when the battery goes, the power goes too. But for the price, it's still we'll worth it.

It was a little tricky to get the one battery terminal connected, but once done the unit works perfectly. This review should really be done in 12 months time.

CyberPower - 650VA Battery Back-Up System is very reliable, you don't have to worry about it in a first 3 years, after that more than likely internal battery has to be replaced.

My power went out for several minutes but my modem was connected to the CyberP and the computer remained connected to the internet. Just the reason why I purchased it for.

Very high quality surge protector. Plenty of outlets and long lasting backup....

Good Value, this is the second one of these I have purchased, the last one lasted 3 years, through several power failures without replacing the battery.

Have suffered a few power spikes and short outages in the utility service to the house, this HAS protected my equipment and kept the electronics in service as it should. Need to see how long battery lasts to solidify opinion

Definitely a sound investment to protect valuable equipment. I used this to protect my CCTV DVR which was damaged by a power surge that cost me over $100 in repair.

Great value for multiple outlet protection. Has already worked just as advertised when we had a weather related outage. Time to save and safely shut down! Perfect.

Works great giving me confidence that my computer and monitor and printer are protected. Also gives me time to save my work and shut down when the power goes out!

Bought this to replace old back up that was about 6 years old. This is smaller and lighter. Since the previous one performed well I stuck to the same brand.

Great back-up for the PC's in the office for our AutoCAD users. With the resent storms and power losses, they had time to save their work and power down safely.

This is a great value for this battery backup. Our power surges were wrecking havoc with my Mac, and I didn't want to take a chance on losing everything again.
