Battery Charged message

Is there a way to turn off the sound warning about the battery being fulled charged without muting the phone? Charge of course always happens in the middle of the night, so I wake up thinking something critical is happening (which is why I don't want to mute my phone in case there is something critical)...but I can't seem to find what setting lets you choose the sound (which of course I'd set as silent) for that message.

Does anyone know where to find it?
