Can a character Mastermind Damage to a Power Battery?

I'm not up to date with WoL, but Power Battery seems to be a Resource not a character. Master Mind only works on characters.

You can't mastermind to the power battery because the only way to "damage" it is to take a power action to do just that. Mastermind wont work.

This is correct. Just because it is on the map and can do certain things "like" a character does not actually make it a character.

This is incorrect! I'm just talking about the only way to damage the battery part.

Plus you can push the Battery, too. and since it's colossal it can use colossal stamina! So damage away!
