Hello guys I have a Back-UPS RS 800 that refuses to charge the batteries.
It used to work great but eventually it died. I took the batteries out to find they were at 0.1 volt (in series) so basically 0.05 volts per battery. I did the usual adding water and charging on a universal powersupply but there were shorted cells. I brought in a lawn tractor battery and a small atv battery and hooked them up in series. They didn't last very long under a pc load but they hadn't been charget forever. After a while of tinkering with it the batteries got too low and the backup started giving me the usual your batteries are screwed warning.
It doesn't put out any voltage and when the batteries are hooked up the voltage is less than when they are disconnected. http://www.heime.org/post/17 This post is for the 500 model and it shows that the issue is a bad cap but I was unable to locate such a capacitor on this board. If you guys could point me to this cap or the actual issue I'd be real happy.
Right now all it is is a surge protector.
