I live in Asheville and the hurricane has closed my dealership. I need a new battery installed. The owners manual says I should take my ‘02 C5 to the dealer to change the battery. I see no difficulty in changes the battery physically, but is there some other concern? Perhaps something to do with the onboard computer?
I wonder why the manual calls for taking it to the dealer?
There is no reason to take it to the dealership. I have done multiple battery replacements myself on my 2001 C5. It’s very simple. I use a sealed size 78 with side posts. Most automotive stores have what you will want and most will install it for you at no cost.

Yes, you can just change the battery normally. The biggest negative is the the PCM will lose any stored adaptations - and all emissions"monitors" will revert to not wet.
IF you want to - you can hook up a "spare" battery - or a "jump box" or even a battery charger set to supply 13.5 or so volts to keep the electrical system happy - hook it up to before you disconnect the old battery - and keep it hooked up till the new battery is connected. Hook it up to something "live" at all times...

or any of many different similar devices.
If you're using a power bank make sure you test how long it will stay on with such a small load. Some shut down after a few minutes.
I'm on my second C5 and I assure you, I have changed both Corvette batteries with a AGM battery I usually go with a Optima Red-Top. put I only use a AGM battery for the simplist and safe they provide., My cat could do it. Take the one in your car now, get the battery and reverse the process. It is a real no hogy fanogy, it is a stright in - out process. And when you put the new battery in ( Make sure it has a good to full charge) and once you clean the terminals ( Do this just before you put the new battery into it's new home and when you connect the new terminals ( Put the positive terminal on first and the ground second ( Althought nothing bad will happen just it is dramatic doing the postive first ) and when you connect the ground your going to hear a lot of modules coming back on-line and it lasts about 1-2 min utes, so don't be alarmed with any noise, you'll need a 10mm wrench and a 13mm to take the battery hold down off. the noise it goes away. good luck Easy Job !

Nothing special about changing the battery in a C5. Very easy - just remember to put the battery hold down wedge back in place when you install the new battery.
My procedure: On my top post battery, I disconnect Negative connector first, put a plastic cap on the post, then remove the Positive connector putting a plastic cap on that post. Unless the old battery has a built in handle to remove, it is difficult to grasp the battery for remove the battery and the caps help keep an electrical discharge from occurring during removal.trying to thwart Murphy's Law. If the new battery does not have a built in handle, I make one to put on the battery before installation.

I'll second this.
Resetting the smog monitors is not trivial. I have 600 miles on my car since I had to disconnect the battery, and still "evap" is showing not ready. in my state I need all sensors to read ready, some states let you get away with one or two.
In the subject FWIW, I recently changed the barrery in my 03, and I thought maybe I could offer some insides I have on the parasitic draw on a C5 battery. When I installed the battery 2 weeks ago I first charged it leaving on terminal , disconnected and fully charged I used my multimeter and it was at 12.73 volts, I left it unconnected for exactly 7 days and it has 12.24 volts. Not sure how much parasitic draw in normal but this is what I read.
