Disconnecting Battery causes a reprogramming operation ?????
I am taking delivery on a 2008 this week and wanted to put my brand new yellow top battery in the 2008. My dealer says this will require reprogramming if we take the battery out. Here are the dealers comments.
"All the vehicles electronic memory is somehow connected to constant battery power and switching batteries is a major ordeal. For example; we had a convertible in stock that had something left on and caused the battery to die. When we recharged or replaced the battery, everything had to be reprogrammed to operate (i.e. the power top wouldn’t work up or down). So, I’m no sure that swapping out the battery is such a good idea."
Does anyone know if this is true????

AFAIK, the ONLY thing that you'll have to reset is window indexing - and that takes about 10 seconds (read in you owner's manual how to do the very simple procedure).
Don't worry about it - swap out the battery if that's what you want to do.

I don't think your dealer knows what he's talking about.

The dealer is wrong. Only thing you'll have to do is reset the window index like mentioned earlier. The directions to do that is in the owner's manual and is real simple.
He is clueless. Vehicle memory is not tied to constant battery power. Maybe 20 years ago you use to lose your radio presets. But memory is different these days. I don't know what the technical computer lingo is for this type of memory - flash, rewriteable ... something like that. But once the program is flashed into the module, it's there, doesn't require constant power to stay there. That's why mail order tuners can ship you a programmed ECM.
The 08 battery should be fine for many years. But if you like the Optima, to each his own. If the dealer is hassling you, I'd just change it yourself. Pretty easy to change the battery in these.
Just make sure everything is off when disconnecting/reconnecting the battery. Close the doors, remove fobs, walk away, make sure everything shuts down. Then swap the battery.

Nearly everything now days is "Non volatile memory" meaning just what has been described above.

Raise the window and hold the up switch an extra 3 seconds. Release. Without lowering the window, hold the up switch again for 3 seconds. Release. Done.
This is called resetting of the window indexing or power window initialize and is in the owner's manual.

If you are real worried about it, connect your battery charger to a ground point, like the altenator, and the + cable, therein ensuring a constant 12v supply.
I do not think it is necessary, mind you this is free and easy if you have a battery charger or tender.
