Test/review of Sofirn AA 3800mAh (White-Black)

Sofirn AA 3800mAh (White-Black)

Official specifications:

  • Brand: Sofirn

  • Voltage: 1.2V

  • Chemistry: Ni-MH(Nickel Metal Hydride)

  • Typical capacity: 3800mAh

  • Minimum capacity: 3750mAh

  • Rechargeable Times: up to 1000 times

Maximum temperature raise at different discharge currents: 1A:+1,6°C, 2A:+4,1°C, 3A:+6,9°C, 5A:+12,4°C, 7A:+16,7°C, 10A:+16,4°C
A NiMH with record capacity from a cheap brand, that is not realistic.

Discharge curves tracks in an acceptable way for NiMH and looks acceptable for the capacity. The problems is that the capacity is only 1500mAh, not the stated 3800mAh or in the 2000-2700mAh range that is very common, but less.


This is not a high capacity cell as marked, but a low capacity cell.

Thank you very much for the report. When a brand needs to lie so much …. better not to trust any of them.(I will not buy his lights)

( ͡° ͜ʖ ͡°)

Another fake, well exposed. It would be nice if they learned anything from this, but I doubt it.

At least we learn from it and can educate others :)
