Test/Review of Unknown 17355 3.0V 1000mAh (Green)
Unknown 17355 3.0V 1000mAh (Green)
Official specifications:
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). Conclusion 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. Notes and links How is the test done and how to read the charts How is a protected LiIon battery constructed More about button top and flat top batteries CR123A and rechargeable substitutes
