I have 4 of these units. Two on TV systems and two on Computer systems. They have saved my bacon on several occasions. When one went dead, I ordered a new battery from here. It arrived in short order, was easily installed, and everything is working fine.
I have 4 of these units. Two on computers and two on Home Entertainment setups. This is the second one that has died. Both times I ordered new batteries which arrived within a few days. Installation was easy and the old batteries went to our local electronic waste collection center. Thanks for the prompt service.
I am giving the SmartPro 120V 500VA 300W UPS 4 stars out of 5 instead of 5 because of the DB9 interface. The network card option would be a good idea only if it were more cost effective. Other than the user interface the UPS is quite and an awesome buy for home or small business.
I have always used APC UPS systems since the mid 90's and never had any issue with any of them. I even had a Network Air portable A/C in my house that was fantastic, and still running. This unit seems to be quite capable for what I needed. I am running 4 WD NAS Drives (each draw 40W peak) and a laptop running windows 2003 server for Domain and admin functions. Setting up was quite simple and there was also verification from the engineer that tested the unit on the side of the plastic case. It runs cool and quiet (checked a few times) and tested it 2 times by pulling the master power feed and letting the unit beep for over 50 minutes, before plugging it back in. I have a linux script that runs on the server when the laptop battery hits 80%, sends a shutdown command to the NAS drives and then after 20% shuts itself down. Bottom line, this will go for over 50 minutes keeping power alive. We have a new built house and have had some power fluctuations and 2 power outs since, so this is perfect for me. Thinking of getting a few more for desktop systems. Although I am sure they will not last 50 minutes on battery. Only thing I would like to see added is a way to acknowledge and silence of the beeping alarm.
