If you have one of these $50 amazon TPMS units, replacement batteries for the head unit are not available.

My head unit battery "done blew up" because lithium batteries just LOVE the heat. Went searching for a replacement and struck out on finding the correct one with the connector type. So ordered one off of amazon and did a little soldering.

You will need battery number 603035. $10 on Amazon. Again it will not have the correct connector type for the head unit.
You will need to swap the wires from the old battery to the new one, it will require soldering in a tiny space, tiny wires, positive and negative right next to each other, so do not over solder.

Saved me $40 for 2 minutes of work.
