If both codes came on at the same time and you didn't take the battery cable off, you need a purge solenoid. $40, it's located near the master cylinder. Mopars eat those things.
Battery disconnected within last 50 starts. Will go away eventually. That code by itself though should NOT illuminate the Check Engine Light. If that is on, you likely have another code besides P1684
Battery disconnected within last 50 starts
P1684....Battery disconnected during last 50 starts
check the gas cap....if it is tight and sealed, could be a small leak in a gas line
