 ## Description
 
-TBD
+Saves battery-backed information (e.g. battery-powered cartridge RAM or Real Time Clock information) from the emulator instance into the file at `path`. Returns `0` on success and a positive `errno` value on POSIX failures. Will do nothing and return `0` if the currently loaded ROM has no battery-backed information.
 
 ## Thread Safety
 
 `GB_save_battery` must not be called if the instance is being run in another thread, but may be called from the current one (via a callback).
