IEC designation PR43.
AC41E equivalents
Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| 675 | 11.6 × 5.4 mm | Same 11.6 mm diameter, but 5.4 mm tall instead of 4.2 mm. Only if the holder fits; thinner cells can lose contact. |
Do not use
These are the same size or a similar code, and they are not equivalents.
-
SR43
Not an equivalent. AC41E is the same size, but it is a zinc-air hearing-aid cell: 1.45 V, it needs its air holes left open, and it starts draining as soon as the tab comes off.
-
LR43
Not an equivalent. AC41E is the same size, but it is a zinc-air hearing-aid cell: 1.45 V, it needs its air holes left open, and it starts draining as soon as the tab comes off.
About the AC41E cell
Activate by removing the tab; not a substitute for alkaline/silver cells of the same size.
AC41E questions
- Is PR43 the same as AC41E?
- Yes. PR43 is another code for the same cell: zinc air (hearing aid), 1.45 V, 11.6 × 4.2 mm.
- Will 675 work in place of AC41E?
- Same 11.6 mm diameter, but 5.4 mm tall instead of 4.2 mm. Only if the holder fits; thinner cells can lose contact.
- Can I use SR43 instead of AC41E?
- No. Not an equivalent. AC41E is the same size, but it is a zinc-air hearing-aid cell: 1.45 V, it needs its air holes left open, and it starts draining as soon as the tab comes off.
- Can I use LR43 instead of AC41E?
- No. Not an equivalent. AC41E is the same size, but it is a zinc-air hearing-aid cell: 1.45 V, it needs its air holes left open, and it starts draining as soon as the tab comes off.
