Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| 6LR61 alkaline 9 V | The rechargeable is seven cells at 8.4 V or six at 7.2 V, and around 200 mAh against 565. Smoke alarms are certified for the alkaline or lithium 9 V and can chirp low-battery from day one on a NiMH. Fire regulations in several jurisdictions require the specified cell. |
Where it turns up
- Guitar effects pedals used regularly
- Wireless microphone transmitters
- Test equipment on the bench
- Anything on a charger between sessions
Nominal voltage is 7.2 V (six cells) or 8.4 V (seven); 8.4 V is the more common modern build. Capacity 150–300 mAh depending on cell count and construction.
