Hello all Hoping to get some advice. I have never charged a car battery before. My 2009 aurion won't start after sitting in the garage for a month. I bought a battery charger (Calibre Battery Charger - 12V, 8 Amp, 3 Stage Intelligent Pulse) from supercheap auto. I plan to charge the battery in the car. The manual stated that I will need to disconnect the ground cable and remove the vent plugs I was wondering if disconnection of the ground cable necessary? I checked a few on-line videos and others have not done this. Furthermore, I do not know where the vent plugs are. I have attached a photo of the battery. There is nothing on the sides of the battery Thanks in advance
