It's just the angel eyes that would be on though. But when I took the car in for a regular maintenance, I was told that it was time to change the battery.

So just because it does not appear to be on the outs does not mean that it's not on the outs. My e46's battery lasted for 10+ years, similar to your E39. But remember those cars in no way tax the battery like the F30.

If your SA does not tell you that you need to change the battery at your next scheduled maintenance, ask him/her to do a quick check to see what your battery's status is. You may be surprised to find out it's nearing it's time OR it may be prime time to change.
Smart chargers(e.g. CTEK) supposedly have battery tests done to indicate good/bad, right?

My CTEK MUS 4.3 detects sulfated battery, and test if battery can accept charge.
