When starting car,seems to be 'cranking' slower,taking few seconds to turn over.

so, car starts after 2-3 seconds of cranking? I have had several Hondas and this has always been the case. Mechanic may say battery needs to be replaced, but mine have always started so I believe all is well (never failed to start even on coldest of days (below 10f..maybe took 3-4 seconds..)
