Need new batteries for your hearing aid? Clas Ohlson sells a range of different sized button-cell batteries for hearing aids. The smart thing about our batteries is that they only start losing their capacity once they are exposed to air. This means that they have a much longer shelf life. It also means that there is no reason why you shouldn't stock up on them now to make sure that you always have spare batteries at home when you need to replace the old ones. It is also important to keep your hearing aid clean. Our pocket-sized hearing aid cleaning kit contains tools for cleaning hearing aids and changing batteries as well as a couple of slots for keeping spare batteries in.
