I’ve recently gone to replace the battery on my Ruuvitag but have accidentally snapped the negative contact clip that overhangs. I’ve tried looking for a replacement online but to no avail.

Does anyone know a part number for a suitable negative battery contact?

Hi bth, sorry for such late reply!

This is a custom part in RuuviTag and there are no spare parts available.

However, this issue is fixable with a bit of DIY by simply soldering a piece of metal to make the connection to battery functional again, difficulty level is easy.

You see the connector part in action here:
