UPS power supply
I was in my dad's store today and saw an old backup power supply not being used so I brought it home to see if it works. I got it home and plugged it in. I plugged in the tv and it got power but if I unplug the ps from the wall it goes dead. I'm assuming the battery is dead and needs to be replaced. It's a tripplite 750a. Would it be worth it to get a new battery and where could I get one?
