Electric fence charger on a car battery?

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?

I never set one up but a man who owned a pasture I was renting ran a hot wire from a 12 volt car battery. The horses really, really respected it.

Are your older chargers 110V?

Can you run an insolated hook-up wire under the drive way, connected to your solar charger?

Bret, no, I'm afraid my solar charged is a couple hundred feet or more away. I have mostly woven horse wire fence, some goat panel fencing and some woven field fence too. There is a half way good feild fence on the sides of the drive way and gates. But I want to use an electric wire to keep the goats off my truck.

Not sure what the writer meant but there are alot of fence chargers that run on a 6 volt/12 volt battery. Mine uses a 12 volt battery and I have one that runs off 2 D batteries. As far as hooking a 6 volt battery to a 120 volt fencer----I do not see it happening without some modification or inverter.

If you have a DC charger, it may run on either 6 or 12 volts. If it is a 12v fencer, it will run on a car batter just fine. The main difference between batteries is how they are optimally designed to charge and discharge. Car batteries are mainly designed to discharge a lot of amps quickly (to start the car) and to recharge somewhat slowly. Marine, forklift, and fencer batteries are designed primaly to charge quickly and to provide a little power for long periods.

So yeah, if you have a 12 volt fencer, it will work fine with a car battery. If that is all you use the battery for, though, you would be better to get a marine battery. Remember, too, that a charger that may run for a month on a battery, may only run a week or two if the fence is partially shorted by weeds etc.

A battery powered charger may be the ticket.

There are 6 volt, 12 volt, and 110 volt zappers.

If you want to run a fencer off a 6 volt car battery, it will work well and last a long time, BUT you need to be starting with a 6 volt zapper......

Or a 12 volt battery and a 12 volt zapper......

I always used a 12 volt car or truck battery on fences in remote areas. If the fence isn't shorted out, the battery will last a month or more. I kept 2 older used batteries and always had one at home on the battery charger ready to switch with the one on the fencer.

Don't think it works to use a battery on a 110 ac fencer tho. Best use a fencer designed for 12 volts.DC

Or just spend a little more and get a good solar fence charger. It will have the solar panel, the battery and the charger all in one convenient little package that you can hang at a good spot and pretty much forget... well, other than taking care to keep the weeds off of your wire, which you'd have to do anyway.

Good solar chargers will have a decent battery built in that should last for years and should have enough battery capacity to run the fence for weeks with no light at all.

You need a zapper that works on 12 volts. Ours runs for weeks before recharging.

Thanks, I'll read up on the fencers I've got sitting around. And see what that extra truck battery is like. Maybe I've got enough on hand to do the job correctly for a temporary fence. I don't need to spend money on yet another project. The dollars are flying out'a here lately!

It doesn't take a 'good' battery to run a fencer. Something that won't hardly start a car will work, you just will have to charge it oftener.

12 volt fencer is enough the make your bones hurt if you are grounded good. Think of as bare foot as in an animal on damp ground. You can hear it hit them. Keep the weeds down.

I used ice melt salt dissolved in water and use a sprayer on the fence line. A good soaking is good for a long time as in months.

They make a fence charger specifically to use a 12 volt battery. I have one made by Pharmak(sp?) It does not have the jolt that a 110 volt charger has.

Cows, you can get 12 volt fence chargers that will have the "jolt" of a 110 volt one. I got a 12 volt one that if you get a good ground and touch the fence----after getting away from it--It will make you stand there and try to regain your sences before moving on. Worse than any 110 volt one that "I" got. My neighbor has a 6 joule battery operated one. I hit it by accident---it took me several hours before I felt normal(for me--lol) again.

I have not checked but I do remember seeing a 18 joule battery operated one---it would probably stop your heart if you got on on Good.

I used 12 volt battery for pigs on one strand of wire on approx. 1/2 and acre and it worked fine. I charged it about once a month.

A butcher friend of ours used as 12 volt battery on a 3 strand fence for his cows and charged it about once a month. If it didn't work, the butcher most certainly wouldn't have wasted his time with it.

the output of the 12 volt charger depends on how many joules the charger is made to output. large output and hardiness will cost $250 and up. i have galligers (spelling) that run off batteries charged by solar panels that run 5 string high tension fences that are miles long. you don't want to be shocked by it....12 joule output if i remember

i have several of the 6 volt solar pakmar (spelling). they were just not enough output to maintain my fences with cattle.

Ive been using one I bought from these folks

you want to get one like they have that pulses the charge and allows the person or animal to back off the fence once zapped.

We live in dry country so we use electric mesh fence around rhe chickens to keep coyotes out. One strand is hot and the next is ground, and so on. Coyotes, and our dogs, don't need to be grounded to earth to get a shock. Once or twice poking their nose in the mesh does it.
