If you need to protect your horses, dairy cows and beef cattle in a remote area or for a relatively short period of time, the battery operated fence energizer may be the perfect solution for your farm or ranch. If access to an AC power source isn't practical, our 12 V battery operated energizers offer the same Ultra low impedance technology while the D-Cell provide Low Impedance protection for animals of all sizes.
If you contain your horses, cows, cattle or other livestock with electric fencing powered by the Power Wizard battery fence charger, we recommend using fresh alkaline batteries or rechargeable batteries. Many dairy farmers and cattle ranchers purchase two rechargeable batteries so they are never without power. Make sure you check your battery powered fence energizer periodically to ensure continuous, effective shock sensations.
What is a joule rating? A joule is a measure of electrical energy. Power Wizard energizers are rated in output joules, indicating the energy/power of the fence energizer and the fence wire. The higher the joule rating, the higher the shock pulses and the more powerful the fence energizer.
*Note: To determine what charger to use for 4 strands of electric fence take the length x width = square footage. The square footage divided by 43,560 = the # of acres you have. Acre listing is given for each charger. Just pick the correct charger for your number of acres.
