Did I miss something? I am reading the Storey's Guide to Raising Pigs and in it the author says a 6 volt car battery can be used to "propel" an electric fence charger. Really? Have you ever tried this? I have several older fencers that I could rig up in temporary situations and this idea would be very useful/economical. I currently have a solar fencer set up permanently on a fenceline for the horse. But I could see using another fencer to allow my goats to clean up my side yard and drive way. Is it possible that a fencer uses so little charge to operate that a car battery would work for a month or two before dying down? Then I could charge the battery on my battery charger and have it for the next temporary situation?
