gkrellm-ThinkBat is meant as a replacement for the default battery meter in GKrellM. It should look like default, only it optionally shows time remaining/power consumption. It currently supports only one battery.
Latest version: 0.2.2 (2006-02-13)
Download the tarball.
$ make install
this installs gkrellm-thinkbat.so to ~/.gkrellm2/plugins. You can copy it manually elsewhere.
Please report any bugs or suggestions to User_talk:rasto.
Thomas Coppi has a patch for supporting a second battery(it will show the status of whichever battery is being charged/discharged instead of only BAT0) here
