CyberPower 1500VA/1000W PFC Sinewave UPS System

I have now owned two of the Cyberpower battery backups. I have four APC battery backups. I finally had to change my batteries. Wow, not as easy as the APC. Two batteries positioned in a perpendicular way as opposed to the APC. With the APC, just slide out the old batteries, and slip in the new ones. Hook up the red/black wires and you're done. Not the Cyberpower, unscrew the back panel, carefully take the panel off. Then there is a small panel over one of the batteries, remove the panel by taking out the two screws holding it on. The front panel has a ribbon cable, either be very careful or it is possible to take it off. Now the fun part, slide out the battery, remove the Red/black/yellow wires. Then slide in the new battery in. Install the black wire, red wire. Then push in the other battery and connect the wires for this battery. Then reinstall the small panel over the battery. Now put the front panel on. Here it requires getting the thick wires push down. After all this I got it back together... 20 minutes later. APC takes about 5 minutes. I had to find a YouTube video to make sure I was doing it correctly. I would suggest taking a picture before disconnecting everything.
