Glad it worked out for you! While testing my main pump, I inadvertently kicked off the backup and the mointor said the battery needs to be changed (yes, changed, NOT charged). Mine's been in since my first flood 4 years ago, now. Luckily, I changed out the bulb-syle float with a straight up and down one on the main pump and we never lost power. That sucker was running about every 10 minutes. I never felt like we got a deluge, just a constant (and sometimes wind-driven) 3 day constant rain here in northern Virginia.
