Batteries drawing after disconnect switched off

I was installing my Xantrex battery monitor system on my Forester's 2 group 27 batteries. I had the kill switch engaged. When the Battery monitoring system was installed, it showed .1 amp draw. When it was in my Winnebago, it showed 0 zero with the battery disconnect switched. Should be zero in the new Forester. That means when batteries are disconnected between trips, the draw will be 19 amps per week. Good thing I keep it in my driveway instead of a storage lot as it would be totally dead in 3 months. The monitor itself draws 18mA in power saving and 32mA normal monitoring, so I don't thing it's that.

not sure how you are coming up with a "amps per week" figure. Any amp draw at all will drain battery over time of course. Why not just put in a mechanical disconnect switch instead of one that uses power to save your battery

Lots of little draws that the factory switch doesn't deal with.

At .1 amp per hour x 24= 2.4 ah per day times 7 =19 ah per week x 4 weeks = 76 ah in 4 weeks. Not place in the under the step battery compartment for a knife switch.

These are common in automotive.
Easy to install and should fit.

This is what I use for the main battery disconnect. It connects inline on the battery cable.

A circuit breaker is not meant to be manually tripped on a regular basis.

Not sure how often you trip it..

That's funny because that is the way we all use them at the power pedestal in campgrounds.

You trip the breaker, plug in, then turn it back on?
Why..

Circuit breakers are marked SWD if they are designed to be used as a switch.

SWD - switch duty. Usually used for fluorescent lighting.
