Unknown 17355 3.0V 1000mAh (Green)
- Capacity: 1000mAh
- Voltage: 3.0V
- Rechargeable Times: Up to 500 times
- Size: 33.5mm(Length ) x 17mm(Diameter )
This is IFR batteries, i.e. LiFePo4 with a maximum charge voltage of 3.6 volt. The actual capacity is much lower than specified.
The two tested batteries has very different capacity.
The charge curve is a typical LiFePo4 charge curve (Voltage drops from 3.6 to 3.4 volt when charge is terminated).
These batteries are fairly cheap, but that does not excuse the huge difference in capacity or the way overstated capacity, I will call these batteries bad.
