New 12v lithium battery draining in My Tesla

[tatyana_bone]

I'm having a frustrating issue with my 12v system! Just replaced the old battery with a new lithium one, following the installation guide perfectly. Here's the weird part: I get messages about air suspension and engine not starting, then the whole 12v system dies within 20 minutes. Tried reconnecting everything, even charged the new battery separately, but the same thing happens once it's hooked back up to the car. Feels like something is draining it super fast. Anyone else experience this after a 12v battery swap? I can't use the main charger because of the port switch blocking it, even though the high voltage battery has plenty of juice.

Is this the same brand or different?

I remember when I swapped my 12V battery. I found out that there was a parasitic draw from something I hadn't noticed before, which was draining the new battery. I ended up disconnecting everything and reconnecting one at a time to see what was causing it. It took some time, but that helped me identify the culprit. Have you checked for any lights or systems that might be staying on?

What type of lithium battery did you replace your old one with? After your 12v battery swap, are you sure everything is connected properly? If you’re getting messages about air suspension and the engine not starting, there might be something else draining the system.

Urhhh, it could be a parasitic draw or a wiring issue. You should check for any loose connections or other components that might be draining the battery.
