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.

Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

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.
