Great cells

The batteries works fine and to everyone's joy, the 14.1 mm +- 0.2 mm diameter specification was too wide. All of my cells was pretty much 14.1 mm +- 0.05 mm. Four of them fit nicely side by side into an unbored D-sized Mag and a bit tightly, but not too tightly, into modamag's battery adapter. Electrical they where fine although I haven't done any exact runtime-plots with them yet. I expect the 750 mAh claim to be just as good as any NiMH capacity claims. They deliver more current than they are rated fore but I can't say how life expectancy might change from that. I found one typo about the data on the webpage. They claim 2.5C maximum drain but the datasheet says 2C. If you don't plan to use them for 10000 cycles, I wouldn't worry so much about it.
