Tronic AA 2300mAh (Silver-Black)
![]() Official specifications:
![]() Maximum temperature raise at different discharge currents: 1A:+1,9°C, 2A:+5,2°C, 3A:+8,8°C, 5A:+16,2°C, 7A:+22,3°C, 10A:+26,5°C A fairly cheap brand of LSD batteries. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() These curves do not trace fairly well, especially not at higher current. Note: I had a glitch on my test station when testing the A cell at 0.1A, that is the reason for the early termination. ![]() On these curves it is a bit easier to see that the A cells is bad at higher current and it cannot even deliver 5A. The B cells performance is more average. ![]() ![]() ![]() ![]() Here it is very obvious that the internal resistance of the two cells are very different. ![]() Conclusion The B cell in my test has about average performance, but the A cell has rather poor performance. If the batteries are used in fairly low drain devices this will not be a problem, but the batteries are not good in high current devices (Anything that can run them dry in less than 1-2 hour). Notes and links The batteries was supplied by a reader for review. How is the test done and how to read the charts Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium
