3 How it works

+
+
+
+

3.1 libnotify lowbat

+
+

+ The principle of lowbat is rather simple. When it's running in the + background, it checks every 4 minutes whether your battery is above 15%. + If that is the case, it sleeps for another 4 minutes. When your battery runs + bellow 15%, lowbat checks your battery level every 20 seconds as well as + sending you a notification using libnotify. You can display live + notifications on your desktop using dunst for example, as well as many + other I'm sure. +

+

3.2 espeak lowbat

+
+

+ lowbat also has an option to send a custom voice message to the use + using espeak. Very handy if you are not in front of your computer or + if you want to bring joy to this dramatic event. +

+
+
+ +
+

3.3 unknown lowbat

+
+

+ Sadly, I wasn't able to test lowbat on machines with more that one + battery. My call is that it will only warn you for the first battery, + but I can't be sure. Try it and tell me! +
