Battery health always reports as 0% in KDE Plasma Battery Monitor widget

Help

Hi, long time KDE user first time poster here.

My problem is that the KDE Plasma Battery Monitor widget always lists my battery health as 0%, even though the battery works fine.

On the other hand, inxi seems to report a reasonable-sounding capacity:

[anton@Biloxi ~]$ inxi -B
Battery:
  ID-1: BAT0 charge: 44.1 Wh (99.8%) condition: 44.2/52.5 Wh (84.2%)

I think I’ve found the source code for the Battery Monitor widget, but I’m not sure how to track down the issue further (i.e. how “batteryCapacity” gets set).

Not a deal breaker for using KDE but would be nice to get it fixed.

Here’s what I’m seeing…
System info?
