675 equivalents
Direct replacements
The same cell under another code. Any of these fits, whatever the brand.
- Blue tab
- ZA675
Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| AC41E | 11.6 × 4.2 mm | Same 11.6 mm diameter, but 4.2 mm tall instead of 5.4 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.
-
SR44
Not an equivalent. 675 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.
-
LR44
Not an equivalent. 675 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 675 cell
Activate by removing the tab; not a substitute for alkaline/silver cells of the same size.
On the shelf it is sold with a Blue tab on the pack : the tab seals the air holes, and the cell starts working, and running down, the moment you pull it off .
