IF I leave the car parked for 2 weeks, do I have to disconnect the starter battery? Will it run dry if I did not?
How about the consumer battery?
What is an accessory battery charge unit? Does it work for both batteries?
Thanks

A good battery should hold a charge for two weeks as long as the car has no parasitic load on the battery.
There are several kinds of chargers. To maintain a battery you want a maintenance charger
