21700 Batteries
The 21700 family on this site covers the Panasonic catalog series NCR2170M, NCR2170N, and NCR2270A. The table below gives the legible dimensions from the catalog data, as carried on the distributor's brand page. Nominal voltage is 3.6 V, with 3.62 V noted for one series variant.
No capacity or cycle-life figure is published on this page. The catalog page carries headline wording for the 22700A line, but headline wording is not a per-model verified specification, so no capacity or cycle figure from it is republished here.
Ask for the datasheet of a named model before ordering, and confirm the exact model, the capacity, the dimensions, and the ordering steps for that model.
| Model | Diameter (mm) | Height (mm) | Mass (g) |

| NCR2170M | 21.20 | 70.25 | 70.0 |
| NCR2170N | 21.20 | 70.25 | 70.5 |
