2013 CRV Charging System Software Update
Found out from my my local Honda dealer there is a software update for certain 2013 CRV's that addresses the dead battery issue common on many CRV's You might want to get yours checked out to see if it is applicable.
Honda Service Bulletin 1255B9 is the reference.
