Notes:

These rechargeables are a Kaufland brand and are obviously non-LSD. The showed up a pretty good capacity on the 1-hour test - 2360 mAh - but are not well balanced, with a difference of more than 100 mAh between cells.

Thanks to Infernus, which gave them for testing!

The batteries had no marked date of manufacture, but featured a code, "4713", which I took to mean "47^th week, year 2013".
