Poor operation
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased this battery backup system to keep my modem in operation during a power outage and it only keeps power on for about 8 minutes. The first one died after a couple of weeks of operation and the replacement is almost worthless.

I would recommend this to a friendCyberPower battery
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I had this product for less then 1 month when it quit communicating with my compute. This is the 2nd Cyberpower battery I have tried and in both cases it works for a very short period and then quits communicating. This leaves me with an expensive surge board and no back up battery.

Decent price, Concerned about Lifespan
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.You can tell that these are cheaply made based on the weight compared to other brands that use good, solid transformers inside. However, the price savings is sometimes what the clients are looking for and consider these to be disposable items anyway

Died about a year after I bought it

Small price for peace of mind!
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Note the batteries in these only last about 5 years. I had a 550VA UPS connected to my Mac mini M4 and Monitor for about 6 years and during a recent power outage when I tried to check on the Mac Mini it didn’t have enough power to handle the monitor coming on and cut the battery output power off - what I did NOT want to happen. So I bought this 650VA recently, and 2 days afterwards we had another Power outage while I was working on the computer - I almost didn’t even notice it because the computer/monitor remained on without any issues! Wait for a sale and nab this unit for a cheap insurance upgrade for your devices plugged in.
I would recommend this to a friendDon’t buy! Horrible and a waste of money!
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It only last for about 10 min and then stops. Don’t buy!

Posted .The exact runtime of the unit is going to depend upon the load attached to the Surge+Battery outlets of the UPS. The more items and/or power drawn from the battery outlets, the shorter the runtime. If you have additional questions, please reach out to our Technical Support team at 1-877-297-6937 and select option 1. Thank you for your review!
