SOURCE: APC Smart UPS 1500 will not start.

It could be that the cable to the front-panel got damaged during the battery replacement.  After all these years you would think APC would improve that aspect of their design.  All I can suggest is inspecting the cable and where it connects to the front panel.

APC RS 1500 82v output


Many UPS Systems have a squared wave when working on batteries. Cheap multimeters do not give the correct measure on squared waves. Connect a 100 watts resistive lamp to the output of the UPS, if the light is almost the same when UPS is working on batteries, everythinf is fine.

Why does my APC Conext UPS beep after power is restored?


After about 2 to 3 years the batteries usually have to be replaced. I found with our UPS's we get about 3 years maximum from the batteries. Ordering the originals from APC is rather expensive.

Locate a professional battery distributor in your area. Get the part numbers written on the batteries in your UPS, and including the detailed descriptions. You can then order these from the distributor. APC uses industry standard batteries. We found the Panasonic and Portilac brands to be excellent.

APC manufactures the UPS's. They use various battery manufactures depending on bid costing.

Beeping


These UPS systems do a self check everytime you press the power button. If the voltage in the battery is too low, you'll get a long drawn out beep. A new battery should solve that problem and it is even economical with a unit this size. Here's a link: http://batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

Simply remove the single phillips screw on the bottom of the unit and remove the battery cover. Replace battery and that's it. Very simple to do.
