Open the frunk. Pull off the air grill and you can see the batt. Few ways to check, first you can see if it says what the batt type is. Mine didn't so I put a meter on it. If it reads around 12v then it's the old lead battery. If it reads around 15v then it should be the new Li ion batt. Check youtube out, there are a bunch of tutorials on how to change or test them. Cheers m8Congratulations! How do you verify that it’s the new 12V battery?
