Disconnect the AC adapter.
Fully deplete the battery one final time until the battery-low warning appears.
Disconnect the AC adapter.
Reconnect the AC adapter and fully charge the battery again. You have finished conditioning the battery.

💡Note:

If the Chromebook will not be used for an extended period of time (one week or more - e.g. holiday breaks); it is recommended to properly place the Chromebook into a "battery disconnect state" to preserve the battery (follow the instructions here).
