BX1200-CN won't switch to AC power after I replaced the battery

[HarryP]

I just installed a new RBC32 battery in my BX1200-CN and when I plug it into the wall and hit the button the top green light flashes for a second and then the yellow (battery power) light comes on steady instead. Any idea what is wrong? I first plugged it into the wall and let it sit for over 8 hours before I hit the button so it should be recharged. This started when we had a power outage overnight and I never checked on the UPS until much later after power was restored. When I hit the button it would continuously switch between the green and yellow lights so I ordered a new battery.
