What Do You Consider When Getting the Best Electric Fence for Cattle?

1. Type of Electric Fence Chargers

a). AC-Powered (Plug-in)

These electric fence chargers are powered directly from your outlet. You'll need to connect the electric fencing charger to the outlet for it to work and keep your cattle inside the barrier. You'll need an extension cable if your outlet is a distance from the charger.

A good example is our fifth pick which is AC-powered. Ensure that you take precautions if you need to use an extension cable.

b). DC-Powered (Battery)

Our fourth pick is a good example of a battery-powered charger. A great advantage of a battery-powered charger is that you can operate it from anywhere you want. In addition, you won't have to struggle to get cables or seal cable paths.

However, you'll need to charge the charger to avoid it going out constantly, and you don't know. Having some batteries handy that you can change is a great idea. Getting rechargeable batteries can be a good investment and is a more sustainable option.

c). Solar-Powered

Our first pick is a true testament to the solar-powered charger. Your animals will be kept safe, and you won't have to spend so much on electricity thanks to the solar panel. These chargers are similar to the DC-powered chargers.

However, you won't have to replace the batteries since they are connected to solar panels. When the sun comes out, the battery absorbs the energy and converts it to electricity. This electric current is then transmitted to the fencing charger.

You can operate this fencing charger for a whole two weeks without sunlight. These types of chargers for wire fences are portable, lightweight, durable, and easy to use. The acid batteries used also have a long lifespan of around 1000 charging days.

2. Joules

The best electric fence for cattle and other livestock keeps them safe inside the fence and keeps predators like wild animals outside. The power needed to shock any preditor that wants to come in is called a joule.

The number of joules that your fences can handle determines how well they can keep the animals away. Different animals can withstand different levels of shock. You need to adjust your fencing charger to suit the animals you're working with.

Here's a snippet of how much voltage animals like cattle need to get an idea of what we're talking about.

  • Cattle: 3-5 joules
  • Horses: 3-5 joules
  • Predators: 3-8 joules
  • Deer and pests: medium power
  • Bear: high power
  • Boar: a large shock of power

Once you know what you want to keep in and keep out, you'll be able to adjust your Jules accordingly.

3. Low Impedance

You've seen us mention this term a lot while looking at the various fences and charges. What does it mean? Low impedance means that the steady flow of current through your wire causes resistance.

When this happens, the power of the electric current will be more while the heat generated will be less. Therefore, getting a charger with a low impedance is a must if you want to power a large wire.

4. Area

The area you want your wire to cover will determine the type of charger you get. The larger the area to be covered by your electric fence for cattle, the more powerful your fence charger needs to be. We've mentioned in the product descriptions how many acres or miles the specific charger can cover.

Ensure that you check this before you decide on which charger to chose.

5. Number of Weeds

When weeds touch your wire, they draw electricity from the fencing, which means more charge will be needed. The more weeds touching your fencing, the more power you'll need. We recommend that you treat the area surrounding your fencing regularly to reduce energy consumption.

If you have many weeds, ensure that you get a fence charger that has low impedance.

6. Ease of Installation

How easy it is to install your wire and fences is a very important factor. You'll get a manual guide with your fences and charger, and you can use this to install your device. Carefully follow the instructions, and you should be good to go.

Nonetheless, some need a bit more than the instruction manual, and you may need to call in for more help. Therefore, you should consider whether you can do it yourself before you settle on the charger to get.

Some factors to consider are whether the case is waterproof or not and if you'll need to use more cables for AC chargers. Also, ensure that you use an insulated ground wire for your safety.
