# SR920SW battery

**What replaces a SR920SW: 371, 370, SR69, SR920, SR920W, AG6**

1.55 V silver oxide, 9.5 × 2.1 mm (diameter × height)

The SR920SW is a single-use 1.55 V silver oxide button cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** SR920SW
- **Nominal voltage:** 1.55 V
- **Chemistry:** Silver oxide
- **Size:** 9.5 × 2.1 mm (diameter × height)
- **Typical capacity:** 34 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? |
| --- | --- |
| 371 | Yes — same cell |
| 370 | Yes — same cell |
| SR69 | Yes — same cell |
| SR920 | Yes — same cell |
| SR920W | Yes — same cell |
| AG6 | Yes — same cell |
| D371 | Yes — same cell |
| V371 | Yes — same cell |
| GP371 | Yes — same cell |
| SB-AN | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| LR920 / LR69 / 171 | Alkaline at 1.5 V with a sloping curve and around half the capacity. Chronograph movements draw hard when the stopwatch runs, and that is exactly where the alkaline voltage sags. |
| SR927SW / 395 | Same 9.5 mm diameter, 2.6 mm tall instead of 2.1. It will not close a 371 compartment. |

> The SR920SW 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

- Quartz chronographs and multi-hand watches
- Seiko and Citizen chronograph movements
- Digital calipers and micrometers
- Small electronic games

## Common questions

### What is equivalent to a SR920SW?

371, 370, SR69, SR920, SR920W, AG6, D371, V371, GP371, SB-AN — all the same 1.55 V cell under different manufacturer codes.

### Can I use a LR920 / LR69 / 171 instead of a SR920SW?

Alkaline at 1.5 V with a sloping curve and around half the capacity. Chronograph movements draw hard when the stopwatch runs, and that is exactly where the alkaline voltage sags.

### Is the SR920SW rechargeable?

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