AAA sized LiIon cells, how good is this brand?










Up to 0.5A the cell works fine, at 1A it has lost some capacity (Sorry, only curve for one cell) and it cannot do anything at 2A



















Conclusion

The performance of this cell is not very impressive, but that is the same for most 10440 cell. The capacity is always around 300mAh and some can deliver more current than other, this one here is not a high current cell!

I see several cells that clearly outperform it in your comparator. I’m disappointed.
Thank you for the test HKJ!
