Widex 675 hearing aid battery 6 pcs

Widex 675 is a special zinc-air battery for hearing aids and hearing aids with a voltage of 1.4V. The battery needs air to operate. Each battery is factory-fitted with a sticker (this model is always blue) to ensure that the battery is sealed and fresh before use. If you remove the sticker from the sticker, the battery will activate itself. It will be charged in minutes. If you remove the sticker from the battery and do not use the hearing aid, the battery will self-discharge in 4-6 weeks. Widex batteries are not rechargeable. Battery life depends on the type and use of the hearing aid.
