Gallagher BA20 (9V/12V) energiser
Gallagher's 9V energisers have been completely redesigned. Without exception, these are powerful battery-powered units that are easy to use, robustly designed and have the quality you would expect from Gallagher. The BA20 model has a black housing with an orange cover. This unit has an energy saving mode, so the battery lasts longer as the unit sends out delayed pulses and changes the pulse strength. The light on the energiser indicates the battery pulse. The BA20 is suitable for larger (mobile) fences.
This energiser is supplied with a connection cable set to connect the battery energiser with the fence and the earthstake. A 12 volt battery can be attached to the energiser, for this you would need connection set 005499.

This is how the energy-saving circuit works:
This energiser has 2 different operating modes. In mode 1, the unit generates a standard pulse with maximum energy. In mode 2, the unit generates 1 pulse with full energy (100 %), followed by 3 pulses with half energy (50 %). This ensures that the battery lasts longer and there is still enough power on the fence.
