In front of the left front tire, there is a removable plastic/rubber panel held in place with 7 or 8 phillips head screws. After removing the tire ( left front) remove the panel. The battery is sitting on a shelf behind the left front headlight.
The panel can be removed without pulling the tire off, but the battery cannot be removed unless the wheel is off.
To get to the screws, you will have to turn the wheel hard right to remove some and to the left to remove the others. Free the panel from against the firewall then pull it out from behind the edge of the left front quarter panel.
