12v battery recharge

12v battery recharge

I went out of town and long story short my car wasnt plugged in or driven for about 3 weeks. Its completely dead. I've opened the frunk but I cant figure out where to plug in the cables to the battery tender. Can anyone help? | 8 November, 2018

From page 151:

Note: When the low-power consumption mode is active, the auxiliary 12V battery is no longer being charged and can completely discharge within 12 hours. In the unlikely event that this occurs, you may need to jump start or replace the 12V battery before you can charge. In this situation, contact Tesla. | 8 November, 2018

It shouldn't discharge that quickly, unless it was already low. Tesla estimates 14% loss per week
