6. Important Notes
- Use a charger specifically designed for Ni-MH rechargeable batteries.
- Do not use lithium-ion or lithium-polymer charging circuits.
- Do not short-circuit, puncture, crush, or expose the battery to excessive heat.
- Observe correct polarity during installation.
- Use suitable battery pack assembly methods when connecting multiple cells.
- Avoid mixing batteries with different capacities, ages, or charge levels.
- The nominal voltage is 1.2V, which differs from the 1.5V nominal voltage of standard alkaline AA batteries.
- Confirm that the connected device supports rechargeable Ni-MH batteries.
- The 2000mAh rating indicates battery capacity, not output current.
- Do not connect the battery directly to a 5V microcontroller power input without an appropriate power supply arrangement.
- Confirm the physical terminal configuration before installation.
