Power Source

THE POWER SOURCE is determined by the energisers location.

Mains power is the most reliable and cheapest form, but the energiser must be located in a weatherproofed building next to a mains socket.

Battery power is the next option, using a 12v battery, 9 volt fencer battery or sometimes 1.5v torch type batteries.

12v wet cell, batteries should be a "leisure type" (Deep Cycle), as used in caravans or on boats, these are designed to cope with a deeper discharge than a car type batteries which is continuous charging as the engine runs. It is important to charge the battery regularly. Energisers stop working before the battery is fully duscharged. It is important not to leave the energiser connected if it is not working, as it will completley discharge the battery, and this can rduce the life expectancy of the battery. Disconnect batteries from the energiser when charging them. Due to their size and weight they are suited to semi-permanent locations.

9 volt dry cell, fencing batteries are designed for energisers, they can last from 3—6 months, according to their capacity. They are compact and lightweight, making them easily portable. Always use alkaline batteries as they are more reliable, and maintain their voltage longer than a saline type.

1.5 volt batteries can be used on smaller energisers but have a shorter life.Battery life can be dramatically reduced on poorly maintained, or badly earthed fence systems. These are only suitable for very short fence lengths.

Gallagher offer most battery energisers with a battery save mode, this extends your battery life by up to 3.5 times, and is not offered on most other makes.

Solar power is also an option, energisers either have a built in solar panel and special battery, or you can buy solar panels to keep your wet cell battery topped up with charge. Solar power is ideal for remote areas.
