| SR60 | Yes — same cell |
| SR621 | Yes — same cell |
| SR621W | Yes — same cell |
| AG1 | Yes — same cell |
| D364 | Yes — same cell |
| V364 | Yes — same cell |
| 1175SO | Yes — same cell |
| GP364 | Yes — same cell |
| SB-AG | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| LR621 / LR60 / 164 | Alkaline, 1.5 V, sloping discharge, well under half the capacity. It fits and it works badly. |
| SR626SW / 377 | Same diameter, half a millimetre taller. It will jam a 364 compartment and can bend the case-back gasket seat. |
The SR621SW is a primary cell and must never be put in a charger. Charging a sealed primary battery builds gas pressure inside a can with no vent designed for it, which is how they rupture or catch fire. Rechargeable look-alikes exist for several sizes and carry different codes — check the code, not the shape.

Common questions
- What is equivalent to a SR621SW?
- 364, 363, SR60, SR621, SR621W, AG1, D364, V364, 1175SO, GP364, SB-AG — all the same 1.55 V cell under different manufacturer codes.
- Can I use a LR621 / LR60 / 164 instead of a SR621SW?
- Alkaline, 1.5 V, sloping discharge, well under half the capacity. It fits and it works badly.
- Is the SR621SW rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
