APC 500LS beeping

[BillP]

Running an APC 500 LS and just replaced the battery. Now the UPS beeps 2x intermittently. I've tried 2 different batteries and left the UPS plugged into the wall for 2 days. I'm guessing this is a possibly a bad UPS?

Anyone have ideas?

Thanks!

I just downloaded and installed the PowerChute Personal Edition. The first thing that pops up is a dialog box that says -

"The battery in your battery backup is disconnected. The unit will not be able to support your system in the event of a power problem until you connect your battery. See user's manual for details."

I've tried 2 different new batteries but the beeping sound still occurs every 30 seconds. The "replace battery" red light flashes along with the audible beeps.

I tried the cold start as you described and it seemed to run fine off of the battery. I even did a self test with the PowerChute software and everything passed.

Hello,

Can we verify 100% that both wires are connected to the contacts on the battery you are installing in the UPS? You can disconnect both and then reconnect them again to be sure. If this is the case, it does sound like your UPS is bad, and I would recommend calling APC Tech Support at 800-890-4272 to have your UPS replaced.

Thank you.
