  • Will 110V charger drain BB if left attached to the BB but not to the 110V?

    I have Schumacher 36V charger that I want to permanently attach to my BB and run power supply cord to the other side of the basement wall where I am about to create generator hook up for it. Now leaving all components connected except gen. will that potentially drain my BB since it will be permanently attached to one of the coils inside charger? Does any one have something similar to be able to provide answer. Thanks!

    You can use a inline amp meter, but be very sure you do it properly, to not blow your meter up. Follow the Mfg's instructions carefully.

    I expect there would be a small drain, in the order of 300mA ( 0.3A ) because of leakage of internal parts. So with a 100ah battery, several days should not be a problem.

      Thanks Mike, so it would be like detecting parasitic draw with multimiter. I can't allow this to happen since it is off grid cabin in the woods closed over winter months. My system is in the fifth year and still going strong.
