Starter battery replacement
After almost 7 years I'm going to be proactive and replace the starter batteries. All the vehicles I've owned the batteries seem to be programmed to fail at 5 years, so I guess I've been lucky. My concern is having to reprogram my radio / CD player. When the batteries are disconnected all is lost, and I have to start from scratch. The radio / CD player is so freaking complicated, that it seems to take the better part of a day to get it straight again.
If I turn the "radio" switch on, will the house battery keep current to the radio while I disconnect the starter batteries? Or, is there a way to disconnect one of the two starter batteries and just replace one at a time to keep current to the radio?
I'm just a real techo-phobe when it comes to fancy electronics and don't want to have to reprogram the damn radio.
