Fujitsu has multiple series of AAA NiMH batteries, here it is the blue version.



I ordered two batteries, but the shop was obvious out of two-packs.









The two cells tracks nicely and capacity drops a bit with load, the 5A test was above the cells abilities.
















Conclusion

Looks like good AAA batteries.
