Hooked up the charger/maintainer that I got from J.C. Whitney today, a Vector VEC080 "Smart Battery Charger". And since a poster in this grp. alerted me that the cigarette lighter connector would not work, cause of the ignition key needing to be in and on accessory, I used the "Battery Terminal Ring" cable, that has a connector that meets the connector attached to this conveniently long enough cable, coming from the unit.
Now my question. When not in use, during actual driving, is it OK to unplug the unit from A.C. (Of course) and just store the unit in the trunk. OR should the unit be disconnected from the cable (Unplugged), going to the cable attached to the battery. I have a friend who seems to think that if you leave it to the cable attached to the battery, that the units circuitry will draw from the battery/electrical system?? The manual does not say either way. So I think that it is designed to stay connected to the cable attached to the battery, and just store the little unit AC cord and all right there in the trunk.
TIA for any info, PLEASE.
