Full equivalents, what does not substitute, and where it is used." url: https://atoneplace.net/battery/sr416sw/ site: "At One Place" --- # SR416SW battery **What replaces a SR416SW: 337, SR416, SR68, D337, V337, GP337** 1.55 V silver oxide, 4.8 × 1.6 mm (diameter × height) The SR416SW 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:** SR416SW - **Nominal voltage:** 1.55 V - **Chemistry:** Silver oxide - **Size:** 4.8 × 1.6 mm (diameter × height) - **Typical capacity:** 8.3 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? | | --- | --- | | 337 | Yes — same cell | | SR416 | Yes — same cell | | SR68 | Yes — same cell | | D337 | Yes — same cell | | V337 | Yes — same cell | | GP337 | Yes — same cell | | SB-AC | Yes — same cell | ## 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. ## Common questions ### What is equivalent to a SR416SW? 337, SR416, SR68, D337, V337, GP337, SB-AC — all the same 1.55 V cell under different manufacturer codes. ### Can I use a SR516SW / 317 instead of a SR416SW? One millimetre wider at 5.8 mm. The 337 is the smallest silver oxide watch cell made and almost nothing else fits its holder. ### Is the SR416SW rechargeable? No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes. ## Related pages - [LR44 battery](https://atoneplace.net/battery/lr44/) - [SR626SW battery](https://atoneplace.net/battery/sr626sw/) - [SR44 battery](https://atoneplace.net/battery/sr44/) - [PR41 battery](https://atoneplace.net/battery/za312/) - [PR48 battery](https://atoneplace.net/battery/za13/) - [SR621SW battery](https://atoneplace.net/battery/sr621sw/) - [PR44 battery](https://atoneplace.net/battery/za675/) - [SR920SW battery](https://atoneplace.net/battery/sr920sw/) - [LR41 battery](https://atoneplace.net/battery/lr41/) - [PR70 battery](https://atoneplace.net/battery/za10/) - [SR927SW battery](https://atoneplace.net/battery/sr927sw/) - [LR1130 battery](https://atoneplace.net/battery/lr1130/) ## Sources - Official vendor product documentation — At One Place (/about/)
