Question Replacing a battery and O-ring in computer

[DanBMW]

Local dealer charged my wife $90.00 to replace a battery and O-ring in two computers. These "puck" type computers seem to be difficult to close so I normally have the local dealer do it. Previously the charge was around $10 each but a new owner has taken over. Did we get hosed?

I replace the batteries (2450s) in my puck computers. I have to take care of the thin o-ring - no pinches when putting back on. Getting the cover off is a bit of a pain. - I have to pry it off carefully. I have done this for 20+ years on various button battery computers. $90 is too much for two (or even one for $45) IMO.
