Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This free software for Mac OS X was originally produced by GGM 41. The application lies within System Tools, more precisely Device Assistants.
From the developer:
Battery Logger is an application to count battery usage.
Application will start count whenever power cable was disconnected from notebook, and will reset the count whenever the power is connected. The program will ignore the count during sleeping, or powered off, but still record these activities for reference.
