Battery Backup Sump Pump and How It Works

With the recent storm activity flooding out the East Coast, the forums are popping with questions about backup sump pumps and how they work.  I thought I'd share these two videos that do a great job of explaining the "HOW" behind a battery backup sump pump system.

This is a short video with a brief description.

If you're looking for more indepth information, this is the video for you.  There is also a demonstration of an installation.
