Kind of different Woodys if you disconnect the battery but use one of these small 9 volt battery things, it just keeps the settings for radio etc. It would not feed back through like a regular 12 volt would if you shorted something out.

It might be a new feature in my 07 but I have disconected my battery a dozen times almost and have NEVER lost my stations. I do have to reset the clock every time, but not the stations.

I've had the same result as well. In fact for a while, I was clearing the MIL by disconnecting the battery, but never lost a station or the time... I was/am confused by that.

Guess I'll have to try unhooking the battery to see what happens with my radio stations then? Haven't needed to pull the battery for anything on my Jeep yet though.. It's been a really solid vehicle.

If you aren't losing any of your settings, that means there is a capacitor built in somewhere .

I was at my locale auto parts the other day and came across this: SETTINGSKEEPER by Noco Cost about $5 It's a thing you plug into a cigarette lighter and it has a 9v battery. When you disconnect your car battery you won't loose any of your radio settings etc. The company that makes it is in Cleveland, OH. I'm going to be extending all my breathers and one is under the battery. So now when I take the battery out I won't have to reset everything. Terry

That sounds cool... I think I'll go google them and see if I can buy one online. This would be great for all kinds of matainence work. Edit: Google provides no links. I'll have to hunt for this locally.

Also that is kind of the point when you disconect the battery so that no damage can be done to electrical systems while you work on it, isn't it. If you are supplying power to the system don't you stand the chance of doing what you are trying to avoid?

Cool, but like i said might just be a new feature on my 07 but never loose the stations just the clock.

Thats what the hamsters do, they keep running on that little wheel to keep things going when the batteries unhooked! (or have you never fed them??)

Knock on wood: Stock Battery Stock Radiator Stock Belt Stock Hoses Stock Thermostat Stock Water Pup Pretty much everything that doesn't need regular service is original... I am hunting for an Optima Battery now though and I am also waiting for my radiator to spring a leak one of these days.

If you aren't losing any of your settings, that means there is a capacitor built in somewhere trickling a charge to keep them. I was looking for a way to make sure I cleared my computer's settings for when I re-geared so the computer would relearn the shift points correctly. The procedure is as follows: Disconnect the positive cable from the battery and touch to ground for 30 seconds. Reconnect the cable. Turn ignition to on (but do not start). Turn headlights on. Turn headlights off. Turn ignition off. Then the computer has to relearn it's operating parameters over the next 50 start up cycles.

I've never lost the settings on my '03. I've had the battery disconnected for hours at a time.

I agree with ATXKJ, there is probably some Flash memory local to the radio/cd player. This would store the instruction set for the radio/cd player to operate when powered, plus is can store user settings. When you remove power from the radio/cd player the internal oscillator loses power and the device can no longer keep time, thus you lose your clock settings.
