Screenshots
Display multiple Battery statuses simultaneously
You can show up to 8 different battery indicators at the same time -- assuming you have the space in your Menu Bar!
Access Built-in Diagnostics
You can see extended battery information and the app will even check your battery's integrity when it starts and let you know it detected a problem
The built-in Battery menu item only shows the percentage of charge remaining. Upper Volta
can also show this and 7 other useful status attributes...at the same time.
This may happen if the width of text used for battery status information exceeds the area
that macOS allots for information. As a rule, macOS will give traditional applications that use the menu
bar (e.g. Finder, web browsers, graphics packages, etc) priority on what to display and will hide information used by
menu bar apps like Upper Volta. You can avoid this by not choosing more than 3 or 4 battery indicators at the
same time. In the future, I will look to warn users about having too many items selected if they
are using a laptop on a lower resolution display mode.
About every 10 seconds except when your Mac is asleep.

At startup, Upper Volta will run a simple diagnostic by check your battery's health. If the response isn't "Good", then it will look at other signals such as your battery's age, temperature, charge cycles and others that suggest it may need to be replaced. There will be cases where you battery is functioning, but macOS views it as unreliable. In these cases, it pays to have it looked at by Apple.
