My 2015 Ram 6.7L sat for 2 weeks went to start battery dead. Recharged battery but only electrical working is seat adjuster and under hood light. The battery's are fully charged? Was running and starting fine when I parked it! Any suggestions on where to check!

Have you tried hooking up a battery charger for say 2 hours
Disconnect the Negative Battery Post first.

How old is your battery ?

do You have 1 or 2 batteries
