The problem seems to be that the battery is called …BAT1 rather than …BAT0

It might be relevant that I'm using a wireless mouse with a battery:

Any idea @kevva?
Need to make sure it's actually the computers battery.
@ed-davies, could you log what you get from res on line 23 or something? And I've published a new version (1.3.0), could you test that too?
Added “console.log(res);” on line 23 which gave output:
{ failedToSetPath: 'cannot refresh' }
Yes, 1.3.0 works. Reports “100%” when running off mains power and “99%” after I'd pulled the plug for a minute or so.
Great 👍
