I had the battery replaced in my 2009 Mazda 5 today, and while driving home I found that when the radio or climate control buttons are pressed, there's a beep that wasn't there before. Nothing else seems amiss, not sure if this is something to go back to the shop about or if I should chalk it up to the increased amperage of the new battery?? Perhaps the dash buttons were always supposed to beep??

 

There is a selection in the stereo menu to turn the beeps ON or OFF.
If the battery was changed without using a memory minder then everything is set to default.
