# LR41 battery

**What replaces a LR41: 192, AG3, LR736, L736, V3GA, GP192**

1.5 V alkaline, 7.9 × 3.6 mm (diameter × height)

The LR41 is a single-use 1.5 V alkaline button cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** LR41
- **Nominal voltage:** 1.5 V
- **Chemistry:** Alkaline
- **Size:** 7.9 × 3.6 mm (diameter × height)
- **Typical capacity:** 45 mAh
- **Rechargeable:** No — never charge it

## Codes that mean the same battery

*Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.*

| Code | Fits? |
| --- | --- |
| 192 | Yes — same cell |
| AG3 | Yes — same cell |
| LR736 | Yes — same cell |
| L736 | Yes — same cell |
| V3GA | Yes — same cell |
| GP192 | Yes — same cell |
| G3A | Yes — same cell |
| SG3 | Yes — same cell |
| RW87 | Yes — same cell |
| 384A | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| SR41 / 392 | Silver oxide in the same can, 1.55 V held flat. The better choice in anything that measures. |
| LR44 | Far larger — 11.6 × 5.4 mm against 7.9 × 3.6. The names differ by one digit and the cells are not close. |

> The LR41 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

- Digital thermometers
- Penlights and otoscopes
- Small toys and glow novelties
- Laser pointers

## Common questions

### What is equivalent to a LR41?

192, AG3, LR736, L736, V3GA, GP192, G3A, SG3, RW87, 384A — all the same 1.5 V cell under different manufacturer codes.

### Can I use a SR41 / 392 instead of a LR41?

Silver oxide in the same can, 1.55 V held flat. The better choice in anything that measures.

### Is the LR41 rechargeable?

No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
