All About Fence Chargers

Depending on where you live in this country, the electric fence charger may have a different name. Some areas call the charger an "Energizer" while other areas may call it a "Fencer". Whatever the name, the purpose is to alter the incoming electrical charge into a safer form of electricity. 






FAQs about Fi-Shock® Chargers


Q:  What is an energizer?


A:  Often called "Chargers" or "Fencers", the purpose of an energizer is to convert the electrical input from a dangerous charge to an effective and safe electrical charge. The energizer, or charger, lowers Amps and increases volts.





Q:  Which charger should I use?


A:  There are three questions to ask before this question can be answered:

  1. What power source do I have?

    If you can use AC (regular outlet) power,

    that would be preferred.   Other options

    include DC (Battery powered) or Solar power.

  2. What is the perimeter distance?
    Each Fi-Shock® charger has clearly marked on it the range of wire that it will charge.  Remember that the range is for one strand of wire, so if multiple strands are being charged then more power is needed.

  3. What animals are being contained or repelled?

    Dogs, cats, raccoons etc., are very sensitive to electrical charges and thus need a smaller charger.  Predator control as well as sheep and large livestock need more power to help in the training process.



Q:  Do I need to protect the charger from the weather?


A:  Yes. Follow the instruction on each charger. Solar units obviously need direct sun light and need to face the sun for best results.




Q:  What battery should I use for my DC charger?

A:  You need to make sure you put the right voltage battery on the charger.

A charger that needs a 4 volt battery cannot manage a 6 or 12 volt battery unless specified by the manufacturer. Fi-Shock® recommends using marine batteries for best results.




Q:  How often do I need to charge the battery?


A:  It depends. Each electric fence charger is different. How often a battery needs to be charged depends mainly on how often the circuit is completed.  In other words, if there are a lot of weeds, grass or branches touching the hot wires, then the battery will be drained faster.


In addition, any animals that touch the fence will drain the battery quickly.  This means that while the animals are learning the fence, the battery will be draining faster.




Q:  I want to fence off some areas on my farm temporarily for
    grazing purposes.  Do you have any suggestions for the


A:  Intermittent chargers are preferred over a continuous charger. Costs will go up slightly but intermittent chargers use less energy and they are safer for the animal.  Either will work, however.
