Although replacing the Sonicare E5000 battery six years ago was supposed to be the last time I’d do that, the poor thing died leaving most of a year’s supply of brush heads in the drawer.
Half a quartet of NiMH AA cells should keep it happy while using up that stash:
The AA cells sit at a jaunty angle due to re-re-using the original contact tabs soldered into the PCB.
I’m getting pretty good at taping the case closed:
Although I have no pictures to prove it, the other half of the AA cell quartet restored youthful vigor to the Norelco T770 beard trimmer. Having interior pictures made finding and popping its case latches so much easier.
If only I could change my batteries that easily …

Speaking of brush heads and power handles, I bought one of these when I thought my handle was going south. (I wasn’t. Pilot error. Sigh.) I haven’t used it yet, but it seems viable. USB-C connection to the inductive charge stand. Love the name: Brushmo.
They also do clone brush heads. We’ll check them out when we’ve exhausted our stash.
Linkie seems to work, so I’ll let it stand.
IIRC, I got Brushmo heads a while back and they worked fine; some other off-brand head had wear indicator bristles that just never wore out.
