A complete table of Nikon 1 system battery compatibility
It took me a while to get this data together, so I thought it might be useful for other camera hoarders collectors:
| Nikon 1 Camera Model | Battery Type | Compatible Charger |
|---|---|---|
| V1 | EN-EL15 | MH-25 |
| J1 | EN-EL20 | MH-27 |
| J2 | EN-EL20 | MH-27 |
| S1 | EN-EL20 | MH-27 |
| V2 | EN-EL21 | MH-28 |
| J3 | EN-EL20 | MH-27 |
| S2 | EN-EL22 | MH-29 |
| AW1 | EN-EL20 | MH-27 |
| V3 | EN-EL20a1 | MH-29 |
| J4 | EN-EL22 | MH-292 |
| J5 | EN-EL24 | MH-31 |
It seems the EN-EL20a is a higher-capacity, 100% physically-compatible replacement for the EN-EL20. They should work interchangeably in all cameras that take the EN-EL20[a], and the MH-27 or MH-29 will charge either battery. See this thread for more. ↩
Although the EN-EL22 and EN-EL20[a] are not physically interchangeable in a camera, the MH-29 charges all three battery types. ↩
