I just had my vehicle serviced and they said their was corrosion buildup on positive battery terminal, suggesting a recommendation for "Battery Service" $39.95. Does anyone know what this means?

yeah, someone is charging you a LOT for what many of us do ourselves, or an independent mechanic might do for $10-$15 .

Your battery is 5 years old or older if it is the original.  It could go at any time.  Batteries are expensive so you would be looking at maybe $150 for a new one, but the installer should clean the terminals when they install a new one.  $39.95 is way too expensive for that service, except for certain Fords that have to be reprogrammed when the battery is disconnected.

How long will the original battery last?

anywhere from under 2.5 to 8+ years

extremely variable, mostly dependent on climate and any abuse the battery suffered.

where I live, 3 years is old for battery - heat is very bad for them. They are expensive enough that having a suspect battery tested is worth the hassle. It's remaining capacity can be tested, checked for dead cells, etc.
