Hello Joerg,

The holder is for two 2032's. 2016's are half the thickness, so twice
as many should fit.

More to the point: since I happen to own a couple of these holders, I
have now gone ahead and inserted four 2016's into one of them. The
holder and batteries are sitting here in front of me as I type this;
the batteries are held securely in place. (A thin wall surrounds most
of the holder's circumference, preventing sideways slippage. A metal
clip on the top prevents slipping out that way.)

I might as well test the assembly under load while I'm at it ...

Open circuit voltage is 12.75 V.

I added a 4k load (to draw 3 mA):
Right away, the voltage is about 12.5 V and continually dropping.
After 5 minutes, it's at 11.61 V.
After 10 minutes, it's at 11.39 V.
(Note, this has used up 0.5 mAh of the 80 mAh life rating.)

Don't know if that voltage drop is acceptable to you; does your
application have a continuous or intermittent load? Guess you'd need
to test them in your own device of course.
