Are there any signs that I should look for that would tell me it's time to look at replacing the battery?

How often should the battery in my 2002 Buick LeSabre Custom be replaced?

Batteries in a majority of vehicles typically last for 4-6 years , some will last up to 10. If your vehicle isn't starting without a jump , then its time to look into a new battery, but also have the alternator checked too. a bad alternator will cause a battery to not hold a charge.

An alternator that's not charging between 13.5 - 14.0 volts with the engine running needs replacement. An working alternator does not prevent an otherwise good battery from holding a charge.
As a rule, car manufactures don't put the best high quality batteries in new cars. If your battery is an original it'll say AC-Delco on it. There are two grades of AC-Delco batteries. The better ones say AC-Delco Professional on the top and sides. They are made in the USA instead of Mexico and have more cold cranking amps @ 0 degrees Farenheit.
The best way to learn if your present battery is on its last legs is to have an inexpensive *load test done on your present battery to see what its reserve capacity is.
