Have a little Giant Sump Pump Backup System (SPBS-12). Been working fine for years, all of a sudden the Alarm keeps going off. If I hit the reset button, it stays off for a minute or so and then starts screeching again. The battery charge indicator LED on the charger is green (charged). The battery itself has a charge indicator and it is also green (70-100% of full charge). I have checked that there is power to the outlet. If the battery is OK and there isn't a power issue, what else could be causing the Alarm to go off?
Is there water? sensor maybe bad, or pump failing to cycle

There is water. Remember, The Little Giant Pump is just a secondary backup system. The separate primary pump is working and pumping out the water as it usually does. the Little Giant pump will only get called into action if there is a power failure.

PROBLEM SOLVED. My original diagnosis was incorrect.
Turns out the main pump was not working properly, even though it appeared to be. So the alarm was just what it's supposed to do - let you know when you are working on the backup pump. Seems the plastic top casing to the main pump broke, right where the lever arm is, so when the lever arm was pushed up by the float, it wasn't making proper contact and turning on the pump. I was able to order a replacement top casing, install it and all is fine.
Thanks to everyone who took the time to try to help!
What does the alarm indicate - that the pump is not working, that the battery is not charged? First thing I would do is make sure the pump is operational. Shut down the primary pump and see if the back- up pump is working.
