Codes that mean the same battery
| Code | Fits? |
|---|---|
| 193 | Yes — same cell |
| AG5 | Yes — same cell |
| LR48 | Yes — same cell |
| L754 | Yes — same cell |
| V5GA | Yes — same cell |
| GP193 | Yes — same cell |
| G5A | Yes — same cell |
| 309A | Yes — same cell |
| 393A | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| SR754 / 393 | Silver oxide in the same can, 1.55 V flat, half again the capacity. |
| PR48 / size 13 hearing aid | Identical 7.9 × 5.4 mm dimensions, but zinc-air at 1.4 V with vent holes that must stay open. Never a substitute either way. |
The LR754 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 LR754?
- 193, AG5, LR48, L754, V5GA, GP193, G5A, 309A, 393A — all the same 1.5 V cell under different manufacturer codes.
- Can I use a SR754 / 393 instead of a LR754?
- Silver oxide in the same can, 1.55 V flat, half again the capacity.
- Is the LR754 rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
