Picked one up from a friend had been sitting in his garage for a while and was going to get rid of it so I offered him $20 bucks for it said he was going to throw it out. I plugged in my desktop/router and stuff only two of five lights light up so it handles it fine. I expected it needed new batteries..When I hit test on it, I have maybe a couple mins at best before it shuts down so I suspected it needed new batteries anyway since it had been sitting a while but my concern here is the heat it puts off. Its extremely hot I know battery backups run warm but to be this damn hot probably not worth investing in new batteries ? Smart UPS 1000
you can call them and ask.
and when they say yes, ask about their battery buy-back program and see if they’ll discount your new battery for sending in the old one.
