Finally time to replace my 2002 battery.

Got a great deal on a BMW OEM one at a local dealer but noticed it was from EXIDE not DOUGLAS which it replaces (I looked up the part num on realoem.com) They both fit the 2002 X5.

Does anyone know if the vent hole on the EXIDE OEM battery is ready to go or needs to be punched out for venting? When I look inside the hole, it looks sealed. Thanks!
