I love doubles tennis. It's fast-paced cooperative athletic chess.

I am working with a group making a mobile device that we are shipping this summer, and we put a big battery in it. The EU passed a rule last summer that goes into effect in June that we need to show that it will retain 80% of its max charge after 800 cycles if we want to sell in the EU. If we fast cycle-it, it can damage the battery, but running it down takes well more than a day. So maybe we can't sell in the EU for at least 2.2 years? Way to go EU... Oh, we also have to drop it on concrete from 1 meter 45 times without functional impairment. Yeah.

can you get this data from your battery supplier rather than testing it yourself?

LOL can you please take a video of your drop test. 45 times is a weirdly specific number.

We won’t be doing it. I think we either ship before the deadline, or no EU. It’s absurd.
