The most commonly used type of hearing aid battery today is the zinc-air battery, which delivers more power than its predecessors at the same size. Just keep in mind that the batteries use air to activate - so be sure to let the battery oxidize for a few minutes after unpacking. After a while it will be a really reliable helper. Hearing aid batteries are able to work even in very harsh conditions - in temperatures from -20 to 40 degrees Celsius. At TIPA.EU you can find them in all major sizes:
10,
13, but also
312 or
675. There are usually 6 batteries per blister pack.
