SR920SW Battery Equivalent
SR920SW is the same cell as SG6, 370, V370, 371 and V371, so any of those codes will fit; LR920 is the same size in alkaline and will work, though it runs out sooner.

Upgrade or downgrade
Same size, different chemistry. Read the verdict before you buy.
| Cell | Chemistry | Voltage | Verdict |
|---|---|---|---|
| LR920 | alkaline | 1.5 V | Downgrade Works, but runs out sooner. Avoid in watches and medical devices. |
Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| SR45 | 9.5 × 3.6 mm | Same 9.5 mm diameter, but 3.6 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
| SR916SW | 9.5 × 1.6 mm | Same 9.5 mm diameter, but 1.6 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
| SR927SW | 9.5 × 2.7 mm | Same 9.5 mm diameter, but 2.7 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
Low drain or high drain
SR920SW is sold under two numbers for the same case size. Manufacturers mark low-drain cells SW and high-drain cells W, which records what the cell is built to deliver rather than how big it is.
- Low drain (SW): 371, V371
- A steady trickle of current: a quartz watch with hands, a thermometer, a key fob.
- High drain (W): 370, V370
- Short bursts of heavier current: a watch with a backlight, an alarm or a chronograph.
Both are 1.55 V and both fit the same holder, so either will run the device. The matched one lasts longer.
