Actually, the device disconnects when voltage drops to 11.9volts for one minute.
The added benefit is that it won't allow the battery to go below the set voltage and therefore won't let a leak caused by a blower or a nav light to deep discharge the battery. While this is not as much as a concern for a deep cycle battery, a starting or combination battery will be damaged and potentially destroyed by just a few cycles of what RG experienced!
It actually is quite a complicated little critter, you can read all the info you want at the parent site at:

Anyway, we have used it on emergency vehicles here for quite some time, and on my own boat as mentioned previously.
Works great and is the simplest/safest/most economical answer to your concern.
Drop me a PM if I can provide you any further info.....
