HR6 battery
What replaces a HR6
HR6, HR15/51, 1.2H2, NH15, Eneloop AA, Ni-MH AA
1.2 V nickel-metal hydride, 14.5 × 50.5 mm (diameter × height)
The HR6 is a rechargeable 1.2 V nickel-metal hydride cylindrical. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

Codes that mean the same battery
| Code | Fits? |
|---|---|
| HR6 | Yes — same cell |
| HR15/51 | Yes — same cell |
| 1.2H2 | Yes — same cell |
| NH15 | Yes — same cell |
| Eneloop AA | Yes — same cell |
| Ni-MH AA | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| 14500 | The same size in lithium-ion at 3.7 V. Chargers are not interchangeable and neither are the cells; a NiMH charger applied to a lithium-ion cell is a fire risk and the reverse can overcharge the NiMH. |
| Alkaline AA | A NiMH runs at 1.2 V rather than 1.5 and holds it flat until it stops. Most devices do not care. Devices that infer charge from voltage — some smoke alarms, glucose meters and older cameras — will report low battery immediately or refuse to run. |
Where it turns up
- Camera flashes and speedlights
- Game controllers and wireless mice
- Cordless phone handsets
- Anything replaced often enough to justify a charger
Standard cells are 1900–2100 mAh, high-capacity ones up to 2500. Low-self-discharge types (Eneloop and equivalents) keep most of their charge for a year in the drawer, which ordinary NiMH does not.
Common questions
- What is equivalent to a HR6?
- HR6, HR15/51, 1.2H2, NH15, Eneloop AA, Ni-MH AA — all the same 1.2 V cell under different manufacturer codes.
- Can I use a 14500 instead of a HR6?
- The same size in lithium-ion at 3.7 V. Chargers are not interchangeable and neither are the cells; a NiMH charger applied to a lithium-ion cell is a fire risk and the reverse can overcharge the NiMH.
- Is the HR6 rechargeable?
- Yes. Use a charger made for its chemistry and never substitute a primary cell of the same size.
