12 Volt Wet Battery Energisers

If the fence is moved infrequently or is semi-permanent and no mains power is available, then select a a 12v energiser together with a 12v 75 Ampere Hour (Ah) leisure battery (22-107). The higher the Ah., the longer the period between recharges. Generally these energisers are more powerful than dry battery versions and can operate longer fences.
