Hearing Aid Battery Size Chart — A10 vs A13 vs A312 vs A675
Zinc-air hearing aid cells are matched by size number and IEC code: the size number must fit the instrument. Capacity scales with the cell: size 10 is the smallest, size 675 the largest.
Equivalent & Cross-Reference
These references are electrically compatible. Always match size and voltage before replacing.
Common Applications
A675 is used every day in these classes of devices — the cell is matched to each duty below, and every pack is tested against the appliance profile before dispatch.
Hearing aids & audiology
Hearing aids and audiology devices: zinc-air button cells are the standard power source for behind-the-ear and in-the-ear instruments — the air-activated system delivers a steady 1.4V discharge with long shelf life in sealed packs.
Medical devices
Medical devices: sensors, monitors and infusion backup. We supply medical-channel same-spec cells with lot traceability and transport documents.

Buying Guide: What Buyers Search for A675
If you are looking for an A675 hearing aid battery, match the size number and the PR44 reference on the old cell before ordering — zinc-air cells stay sealed until the tab is removed, so keep spares in the airtight strip.
Buyers often ask whether A675 works in another hearing aid: zinc-air cells are matched by size number (10/13/312/675) and IEC code PR44 — the size number must fit the instrument, and capacity grows with the cell. See the zinc-air size chart above.
For distributors and OEM buyers searching A675 bulk, price and lead time: we supply from 50 cartons (≈ US$2,000) with volume-laddered pricing, shipping marks and transport certificates — request the current price list for your volumes.
