In a method for adapting the operation of a battery powered electric fence energising apparatus to type of battery the rate of decrease of the battery voltage is determined, and the power consumption from the apparatus is decreased if the rate of decrease exceeds a predetermined limit. Further, the energy required for charging a discharge capacitor (C3), arranged to produce output pulses, is determined and an essentially constant current is drawn from the battery during the charging period of said capacitor. <IMAGE> |
