Sorry to everyone who was waiting for the little logistics hiccup, but I now have 500 new cells in stock! They are from the same supplier but slightly different from the old cells. Take a look:

As you can see, the old cell on the left has a "button top", the new cell on the right a "flat top". This works perfectly fine in the new battery holders, and it causes a less tight fit as well, alleviating any mechanical stress concerns that may have been left after the switch to the new battery holders. These cells fit very comfortably.

In the picture below, an old cell is in the unit in the front, a new cell in the unit in the back. The spring has slightly more room to expand.

The new cells also say they are 600 mAh instead of 550 mAh. I haven't done any testing yet to figure out if they really have more capacity or if that's just marketing. :)
