CyberPower LX1500GU UPS System

Selling my CyberPower LX1500GU. It just went out on me and I'm not sure why. I haven't tried to replace the batteries or anything, so if you're handy with electronics or know how to fix these things, this is a hell of a deal for you. Might just need new batteries but I'm selling it as-is since it's not turning on right now.
