silvestrons bits and bytes | Replacing the battery in my Oral-B electric toothbrush @silvestronsbitsandbytes | Uploaded February 2020 | Updated October 2024, 2 minutes ago.
Tearing down a Braun Oral-B electric toothbrush, and replacing/upgrading the battery inside. The battery in these (or at least in my two) is a single AA nickel-metal hydride cell (en.wikipedia.org/wiki/Nickel%E2%80%93metal_hydride_battery) with a capacity of 1000mAh, and, unfortunately, they can suffer from loss of capacity due to lots of repeated partial discharge. You can usually reverse this by performing a few full discharge/recharge cycles, but that's not really an option when the cell is hardwired into a device.
I had no idea how to pull one of these apart when I began, but thankfully it turned out to be pretty easy, although getting it working again was a bit weird. I probably should have charged the new battery before installing (which I did for my second one) but, hey, you live and learn.
Any feedback is welcome. (and sorry for the audio quality in this one, new mic has arrived so no more booms in future!)

Equipment used!
Soldering station: Hakko FX-888d
Desolder braid: goot wick CP-2015
Multimeter: Jaycar QM-1321
Disclaimer!
I am NOT an expert, I have genuinely NO idea what I'm doing, and mostly just glue things together and use a lot of Google-fu until stuff works. I've been tinkering with electronics since I was a kid, but have no formal training and will probably do things incorrectly. If you learn something from this, that's awesome, but trust me - I'm learning too!
