Berapa Lama Baterai Alat Bantu Dengar Bertahan? (A10/A13/A312/A675)

Durasi per nomor ukuran, umur simpan tersegel, dan cara sel zinc-air aktif.

Hearing aid batteries are zinc-air cells: they sit sealed until the tab is peeled, then air enters and the cell activates. A sealed pack stores 2–3 years; once the tab is off, run time is measured in days or weeks, not years.

Typical run time by size: size 10 (A10/PR41) lasts 3–7 days in a moderate-drain instrument; size 13 (A13) 7–10 days; size 312 (A312) 5–8 days; size 675 (A675, the largest, used in BTE and cochlear processors) 9–14 days. Drain and volume settings move these numbers by a factor of two.

Cold and humidity slow activation; a very dry environment can dry cells early. Keep spares with the tab ON, and keep the pack airtight until needed.

Buy in bulk: we supply hearing aid zinc-air cells in 6-piece blister strips, private label, with OEM production markings and EU declaration documents per batch.
