Question: Need advice regarding a 10+ year old battery

My 2001 Cadillac Deville DHS with 55,000 miles on odometer is still on its original battery. Generator is charging "normal". Am I doing anything wrong by not replacing this battery? I have to admit that I've never previously owned a car with such a long lived battery. Car has always been garaged. If this battery dies while I'm on a trip am I likely to break down? Or, would I be able to continue driving to my destination as long as I don't turn the ignition off?

If the battery dies but the alternator is good, then you can keep driving (and yes, don't turn it off).

It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
