Tronic AA 2300mAh (Silver-Black)







Official specifications:

  • Voltage: 1.2V

  • Capacity: 2300mAh

  • Low self discharge (LSD): 75% after 1 year



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.

Thanks for the review. Good timing too, Lidl in the UK have these (and the AAA version) on sale from tomorrow. Think I’ll give them a miss.

For some applications they might be okay, but definitely not in series.

Thanks for the test HKJ

I have not had a problem with these battery and i must have a few dozen, you can always do a capacity test and group your battery`s for use in flashlights that take more than one cell so you don't get an uneven discharge problem.
