UltraFire BRC26650 7300mAh (Gray)
![]() Official specifications:
![]() This cell is specified with record capacity, but the measurements does not confirm this. ![]() ![]() ![]() ![]() ![]() ![]() ![]() The real capacity is about 2500mAh and the two cells do not track very well when current is above 3A. ![]() ![]() ![]() ![]() ![]() ![]() Conclusion The cell is sold with wrong specifications, the performance is very bad and the wrapper lies about protection. I will call this a bad cell. 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 Compare to 18650 and other batteries
