We have a 2005 Honda CR-V.
My buddy needs to swap the battery out.
He doesn't have the code for his battery we're trying to retain the memory on everything when he swaps the batteries.
Do any of you in the know can tell me if he gets one of them 9-volt jobber-do's
to plug into the accessory outlet on that vehicle, is that Honda set up to where the accessory charging port receives 12 volts with a key in the off position?
Because if that only works with the car running or K O E O, obviously it's not going to retain the memory.
If that is the case that the key needs to be on for that accessory outlet to work, can he just hook up a small battery charger to his battery terminals when he swaps the battery out will that retain the memory or will the battery charger be a smart charger, and not put any DC voltage out without a battery connected to it?
I understand what I'm trying to ask hope I have it written to make sense!
