Help Please: Multiple Labels

Hi. I am trying to program a valueTile to be able to show different labels when it has different values. I have been able to do this with the background color, but not the labels. How can I do this?

valueTile("battery", "device.battery", inactiveLabel:false, decoration:"flat", width:2, height:2) {
	state "battery", defaultState: true, 
    	    [value: "01", label: "Batt: Bad"],
        	[value: "00", label: "Batt: Good"]
	    backgroundColors: [
            [value: "01", color: "#bc2323"],
            [value: "00", color: "#44b621"]
