I have a UPS (battery backup) thats about 3 years old now. It's a CyberPower 500SL. When I turn the unit on it beeps at me three times and does this until I power it on and off 3 times. Do these things have batteries that need to be replaced? If so could this be my problem? Any idea where to purchase these batteries? Any help would be great, -Guru
Yes. Be careful how you dispose of the battery. I use Tripp Lite and they help me replace and dispose of the old batteries. nitro
I have found eBay to be by far the cheapest place to by replacement batteries. Find out what the battery pack ID number is and type in eBay's search.
Catoosa, Thanks for pointing me in the direction of ebay. I was able to find a replacement battery for my UPS dirt cheap.... Thanks again, Guru
