2. Electric Fence Batteries Guide Batteries for Battery-Powered Electric Fence Chargers Different battery-powered electric fence chargers use different kinds of batteries. For example, the Parmak EM-200 use a 12-volt battery, while the Parmak DF-LI-UO uses a 6-volt battery. None of these batteries are provided, so all must be purchased separately. Car batteries will operate the chargers requiring 6 or 12 volts; but boat or golf cart batteries are better-suited to this task, will last longer, and are recommended. Batteries for Solar-Powered Electric Fence Chargers All the solar-powered electric fence chargers that we offer come with their own batteries. Should spare batteries or battery re-chargers be needed, we offer these as well (see the catalog listings for solar-powered electric fence chargers.) 3. Electric Fence Conductors (Hookup Wire) Guide 
The principal accessory needed with an AC-powered electric fence charger is insulated electric fence wire (undergate and hookup wire). This special heavily insulated wire is necessary because ordinary extension cords should not be used or won't work. Using an ordinary extension cord carrying house current to reach a charger at the site of an electric fence is dangerous; and a normal extension cord cannot carry the electric fence charger's output from the charger to a bare electric fence wire because it cannot contain the high voltages (typically 2,000 to 10,000 volts) generated by the charger. Therefore, one should get a length of insulated undergate and hookup wire that is sufficient to reach from the AC outlet to the electric fence, from the AC-powered charger's ground terminal to the electric fence system's ground rod, under any gates, and between any isolated sections of the electric fence that need to be electrically connected. In most cases, because the distances to be spanned are short, the gauge (16, 14, or 12.5) of the selected product's internal metal wire is not important. |
