 ## Description
 
-TBD
+Saves battery-backed information (e.g. battery-powered cartridge RAM or Real Time Clock information) from the emulator instance into `buffer`. Returns `0` on success and `EIO` if `size` is less than the value returned by [[GB_save_battery_size]].
 
 ## Thread Safety
 
 `GB_save_battery_to_buffer` must not be called if the instance is being run in another thread, but may be called from the current one (via a callback).
