Thank you all for your advice. In doing so, I may have damaged something:
the iPod now has a grey screen and emits 2 long beeps. Normal reset does
not help. iTunes recognizes the iPod and restored the firmware. No joy.
Still a grey screen with 2 long beeps. Google shows "2 long beeps" but
seems to be fatal.

Make sure you've really reset it.

If you've successfully restored the firmware and it still doesn't
work, it's not totalled. The display connector is loose. Open it up
again and check these ribbon connectors:

It's really easy to accidentally knock the locking mechanism loose
while replacing the battery. The 2nd photo is the display connector,
which is the most likely culprit.

Be careful as you're working with a live battery connected. Make sure
it's turned off. Try not to drag the cable in and out of the
connector or at an angle. This will short random pins and might do
some damage.
