BTY AAA1350, rechargeable NiMH batteries - first and last impression

Right, since they were not that expensive, I somehow did not make the effort to search on the net for reviews, so I ended up with a pack of BTY AAA1350 rechargeable batteries. From the packaging, they went straight in the charger for evaluation - first discharge with 100 mA, then fully charging them with 200 mA current.

The results are more than disappointing. I should have run the TEST mode of the charger, which should have reported the capacity upon discharge, but this value is usually less that the value during the charging. Anyway the numbers are so bad that this does not matter. One battery stores 78 mAh which essentially means it is completely death. The other three were about 270 mAh which actually fits the reports from other discussions on the net.
