Are there any batteries which turn off automatically when a drain is sensed?

Looking for an auto battery for my 964 with a built-in battery sensor. I recall reading somewhere that there is a manufacturer which produces a battery designed to isolate itself from the electrical system if a drain over a certain rating is sensed.
Any leads?
Thanks!

Found one! PriorityStart! attaches to battery and automatically cuts out battery if charge drops below 11.9 volts and the engine is off!

Thanks!

Sears has such a battery too, IIRC. In addition it had some kill switch function. Sounds like you are all set though?
