Disconnecting Negative = Install Battery Disconnect?
I have a battery tender I use on the two AGM batteries I am storing in my garage until we put the AS in use. I intend to use the battery tender when the batteries are put back in the box on the trailer.
QUESTION: Does (1) disconnecting the negative terminal when the batteries are installed in the battery box and subsequently using the battery tender accomplish the same thing if (2) I install my own battery disconnect switch at the battery box, and then use the tender?
Too many parasitic loads now on Airstreams sucking the fun out of batteries.
