Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| LR927 / LR57 / 195 | Alkaline, 1.5 V, sloping discharge, roughly a third of the capacity. |
| SR920SW / 371 | Same diameter, half a millimetre shorter. It sits loose and cuts out under vibration. |
The SR927SW 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
- Larger quartz watches and chronographs
- Diving watch movements
- Digital calipers
- Medical penlights
Common questions
- What is equivalent to a SR927SW?
- 395, 399, SR57, SR927, SR927W, SR926, AG7, D395, V395, 1162SO, GP395, SB-AP — all the same 1.55 V cell under different manufacturer codes.
- Can I use a LR927 / LR57 / 195 instead of a SR927SW?
- Alkaline, 1.5 V, sloping discharge, roughly a third of the capacity.
- Is the SR927SW rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
