Looking at getting a UPS or 2 for my office. Essentially I want my workstation PC, a couple of NAS devices and WHS to be connected.
What I am unsure of is how long the batteries last for when the power goes off - my workstation has a 1200watt power supply I think (does this matter...?) Ideally the longer the better obviously.
I've heard that batteries need to be replaced every 2 years - is this true?
Any advice much appreciated
