You really should. Probably right now.
I also never understood why we are moving away from alkaline/NiMH for low power devices such as scales. My cheapo scale takes 2 AAA cells which I have to charge like once a year. They are safer and designed to be replaced. And probably also cheaper in production.
This is why you should keep backups, which, for me, includes physical printouts of access data stored in a safe location. That’s also helpful if something should happen to you.
