				987 battery replacement - Do you need a vent with the new battery?
			 
 
			Hi,
 I bought a 2006 Porsche Cayman S.  It needs a new battery.  Local Costco has an Interstate one for a reasonable price but doesn’t have a vent.  This is the one recommended for the car.
 
 Do I need the vent?  If so, any suggestions on a favorite battery?
 
 Thanks
