I will continue using this brand of hearing aid battery indefinitely. On the rare occassions it doesn't work immediately, I open up the battery case and expose the battery to air for a few extra seconds and then that does the trick. It works immediately and there is no waiting period of a minute before the battery activates. I take the battery out of the packet, pull the sticky tab off the battery, which activates the battery once the battery is exposed to air, insert the battery into the hearing aid and put it into my ear. 4 yrs and rarely do I get a defective battery from the packet. Since I only have one hearing aid, the box lasts me a long time. I wear my hearing aid from the time I get up until the time I go to bed, typically 16 hrs a day. The average time a battery will last is based on the usage of time that a person uses their hearing aids and the type of hearing aids that one is using. All zinc-air batteries from Beltone are mercury free. Lifespan: up to 4 days (does not include streaming for frequent streaming, estimate lifespan at 2 days.) Product Details. These batteries last me anywhere from 3 to 4 days which I have no complaints about. Yellow Size 10 hearing aid batteries come four, eight or sixteen to a card, and ship in quantities of 10 cards in a box.
