Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| SR516SW / 317 | One millimetre wider at 5.8 mm. The 337 is the smallest silver oxide watch cell made and almost nothing else fits its holder. |
The SR416SW 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
- The smallest ladies' quartz watches
- Hearing aid programming remotes
- Miniature medical devices
- Jewellery lights
At 4.8 × 1.6 mm and 8.3 mAh this is the smallest cell in common retail sale. Handle with tweezers; a fingerprint on the contact face is enough to raise the resistance.
