A step up from the CR2032

[Hattusa]

So as you may know, most CR2032s are shy of 250 mAh. I'm fine with their size and voltage, but I want something with a capacity of at least 300 mAh while still keeping it under 3 grams.

Does anyone here have experience with really lightweight batteries like this? I'd like to stick with LiMnO2 chemistry but am I just hoping for the impossible?

a 2354 will do 560 mAh at about 6 gm:

a 2430 might be close at 290 mAh:

weight is unclear, but appears to be less than 4 gm
