Information: The special feature of air alkaline batteries is their voltage curve; these batteries maintain a constant high voltage over their entire service life. This guarantees the highest level of livestock safety over the period of use, even when using powerful battery energisers. Our alkaline batteries are also mercury and cadmium free and therefore are very environmentally friendly. The alkaline battery is activated only when it comes into contact with oxygen. Before connecting the alkaline battery to the energiser, the sticker on the cover must be completely removed in order to activate contact with oxygen.
