Ansmann C 4500mAh 5035352 (Silver)







Official specifications:

  • Nominal voltage: 1.2V

  • Maximum charge voltage: 1.5V

  • Nominal capacity: 4500mAh at 0.2C

  • Minimum capacity: 4500mAh at 0.2C

  • Minimum capacity: 4200mAh at 1C

  • Maximum continuous discharge: 6750mA

  • Standard charge: 450mA

  • Quick charge: 1350mA

  • Fast charge: 2250mA

  • Recommended termination: dv: –5mV, dT: 0.8 ~ 1°C/min, T: 45 °C 50°C

  • Trickle charge current: 45 ~ 150mA

  • Continuous overcharge: <450mA (no deformation or leakage within a year)

  • Internal impedance: <20mOhm at 1kHz with fully charged battery

  • Cycle life: >500

  • Low self discharge: >80% remaining after 12 months at 20°C

  • Ambient temperature: Standard charge: 0°C ~ 45°C, Fast charge: 10°C ~ 40°C, Discharge: –20°C ~ 65°C



This is a full capacity C cell from Germany (It is made in China and bought in Denmark).
Maximum temperature raise at different discharge currents: 1A:+0,4°C, 2A:+2,8°C, 3A:+4,6°C, 5A:+8,5°C, 7A:+11,6°C, 10A:+15,9°C, 15A:+20,9°C









Very well matching discharge curves and the cell easily match the rated capacity.















Conclusion

This looks to be a very good quality C sized NiMH battery with lots of capacity and low self discharge.
