if you're losing certain functions because it is not daily driver or vehicle not turning over it is surely worth it. my vehicle would lose easy exit feature, radio pre programs.the car dumps what it considers useless data to save crucial data when voltage low. have dealership hard wire to battery.trickle charge will prolong battery life, after hardwired you'll see a small unobtrusive plug coming from battery just connect/disconnect. saves headaches for sure!
