How to Make an Electric Fence From a Car Battery
Simple electric fence kits can be quite pricey. However, they can also be extremely useful in keeping wildlife off your property and out of your garden. So, rather than paying high prices for a fence kit, make one yourself using simple tools and a charged car battery. Does this Spark an idea?

Things You'll Need
- Post-hole digger
- Fence posts (at least one for every 3 feet of fence)
- Heavy grade wire
- Heavy grade on/off wiring switch
- Standard electrical wire
- Soldering iron
- Copper solder
Instructions

-
1
Place the fence posts in the ground as desired using a post-hole digger. Make sure that all the posts stand as straight and even as possible.
-
2
String heavy grade wire along the fence-line, wrapping it around each post. Make sure to string the wiring along at least two heights along the fence-line.

-
3
Connect the heavy grade wiring from the fence to a small bit of standard electrical wiring. Do this at the end of the fence-line where you wish to place the battery.
-
4
Use a soldering iron to solder the electrical wiring to one side of a heavy duty on/off wiring switch. Make sure that the switch you choose is weatherproofed. Then, solder another short strip of electrical wiring to the other side.
-
5
Making sure that the switch is in the "Off" position, connect the wiring to the posts on a car battery. Do this by simply wrapping the wiring around the posts, and twisting it together to tighten.
-
6
To arm the fence, simply turn the switch to the "On" position. All the wiring across the fenceline will then be electrically charged.
-
7
Cover and wrap the battery with a tarp to prevent corrosive wear on the connection ends from rain and wind.

Tips & Warnings
Place the battery and switch in an easily accessible location for easy maintenance.
Always use caution when working with live electrical ends.

A moron wrote this. This will only work if the thing that you want to shock touches both wires with it's tongue, somehow. You can buy a 12V battery operated electric fence energizer. Use one od these if you want a 12V battery operated fence.

The author of this page is an idiot. Building this will produce an electric fence, but nothing that you can do with other than help your neighbour jump start his/her car. Car batteries are generally 12V at around 350A. Put a spanner across the terminals, and you'll see what this amperage can do. You need a relatively high voltage at low amperage to create an effective electric fence which produces a "shock" pulse. A car battery simply connected to a fence will not work. Any type of DC electrical deterrent which provides a sustained shock at sufficient voltage/amperage is potentially lethal, significantly more so than AC.

woke up in the morning and had a thief still hanging on the fence he couldn't let go because of the charge is this maybe too much?
