Yeah search engines aren’t really trying to help us here… Alas, here I am ^^

Thanks for the suggestion!

I recall someone criticised how nowadays a battery is fitted into every single electrical appliance. They were very much in favour of the good old cord, and the example they brought up was shavers.

It does make some sense. Likely you’re only ever using it at home right next to a power outlet and the battery is one of the first parts to give in.
