We have a pair of 2019 Sonicare that need battery replacements.

I picked up a compatible battery but haven’t taken the time to pull it apart yet. It does require soldering.

The company scrambled the model numbers and it’s not easy to figure out which are similar or even the same.

The obfuscation of product differences, release dates and nerfs to longevity are all over consumer goods.

I hope open product designs + micro hyper local manufacturing capability will deeply erode the power of companies creating these wasteful, capital-driven artifacts.
