+.. zephyr:code-sample:: fuel_gauge
+   :name: Fuel Gauge
+
+   Read battery percentage and power status using MAX17048 fuel gauge.
+
+Overview
+********
+
+This sample shows how to use the Zephyr :ref:`fuel_gauge_api` API driver for.
+
+The sample periodically reads battery percentage and voltage.
+
+Building and Running
+********************
+
+The sample can be configured to support a fuel gauge.
+
+Features
+********
+By using this fuel gauge you can get the following information:
+  * Battery charge status as percentage
+  * Battery voltage
+
+Sample output
+*************
