I think Matt meant the following :-)
Note: nominal-microvolt is not the correct term for termination voltage.
Changed to termination-microvolt

+Battery Characteristics
+
+Required Properties:
+ - compatible: Must be "fixed-battery"
+
+Optional Properties:
+ - termination-microvolt: dead battery voltage
+ - design-microwatt-hours: battery design energy
+ - design-microamp-hours: battery design capacity
+
+Batteries must be referenced by chargers and/or fuel-gauges
+using a phandle. The phandle's property should be named
+"monitored-battery".
+
+Example:
+
+ bat: battery {
+ compatible = "fixed-battery";
+ terminate-microvolt = <3700000>;
+ design-microwatt-hours = <5290000>;
+ design-microamp-hours = <1430000>;
+ };
+
+ charger: charger@0 {
+ ....
+ monitored-battery = <&bat>;
+ ...
+ };
+
+ fuel_gauge: fuel_gauge@0 {
+ ....
+ monitored-battery = <&bat>;
+ ...
+ };
