A general question for y'all

Hi, this is a bit of an odd question but i wanted to know about when people get their hyundai's serviced. Does the mechanic when performing a general service as standard practice check the oil, water, fluid levels etc? Is that just something that is taken for granted as done? I am specifically wondering about checking the battery and it's fluid levels.

Thanks for any comments anyone can make on this!

This is something that is a standard pratice. The batteries in new cars are maintenance free.
