Again got the replace 12V Battery Message

Instead of replacing with another Tesla battery that will last only 2.5 years, decided to replace with Lithium 12V battery.

Before disconnecting old battery, I turned off HVAC and lowered driver side window. Then did a screen power off. Then disconnected the First Responder loop. That connector was tricky until I discovered the orange slide lock. Lots of YouTube videos available to help in replacing the 12V battery.

Disconnected the old heavy lead battery and installed new one. Had to transfer the posts. Cleaned posts and clamps.

As soon as new battery was connected things started clicking and alarm sounded ( as expected ). Then reconnected the loop. Had to re-calibrate the windows. All systems operational now and message gone.

This lithium battery from Ohmmu has a 4 year 100% full replacement warranty.
