Starting problems with your Tesla? It could be the auxiliary battery.
We recently helped a customer whose Tesla became unusable after the auxiliary battery failed. Many owners focus on the main drive battery, but the smaller 12V/low-voltage battery is essential for powering systems, unlocking functions, and allowing the vehicle to operate correctly.
We supplied and fitted a replacement battery quickly, getting her back on the road with minimal disruption.
If your Tesla is showing warning messages, struggling to wake up, or behaving strangely, do not ignore it. The auxiliary battery may be the cause.
