Codes that mean the same battery
| Code | Fits? |
|---|---|
| 393 | Yes — same cell |
| 309 | Yes — same cell |
| SR48 | Yes — same cell |
| SR754W | Yes — same cell |
| SR754SW | Yes — same cell |
| D393 | Yes — same cell |
| V393 | Yes — same cell |
| 1137SO | Yes — same cell |
| SB-B4 | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| PR48 / size 13 hearing aid | Exactly the same 7.9 × 5.4 mm can, but zinc-air at 1.4 V that only works once air reaches it through the vent holes. It is not a watch cell and a watch cell is not a hearing aid cell. |
| LR754 / LR48 / 193 | Alkaline, 1.5 V, 53 mAh, sloping discharge. |
The SR754 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.
Where it turns up
- Older quartz watches with deep movements
- Small medical instruments
- Electronic locks
- Digital tyre gauges
Common questions
- What is equivalent to a SR754?
- 393, 309, SR48, SR754W, SR754SW, D393, V393, 1137SO, SB-B4 — all the same 1.55 V cell under different manufacturer codes.
- Can I use a PR48 / size 13 hearing aid instead of a SR754?
- Exactly the same 7.9 × 5.4 mm can, but zinc-air at 1.4 V that only works once air reaches it through the vent holes. It is not a watch cell and a watch cell is not a hearing aid cell.
- Is the SR754 rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
