C6 - battery swap using a CTEK 25000 to maintain power

Recommended Posts


Car is a 2011 GS A6.


Time to swap out my rear cubby mounted Braille battery. I  have a CTEK 25000 with a maintain power function I'd like to use during the battery swap to avoid losing my settings in the car.


My question is this - can I hook it up and maintain power during the battery swap safely as long as I follow battery removal / install protocols?


Removal of battery - disconnect Black lead first, Red lead second.


Installation of battery - connect Red lead first, Black lead second.


I will be attaching the CTEK to the engine compartment ground and power lead not to the cables in the cubby.


Am I good to go or missing something? Probably overthinking it but would hate to damage any electronics during the swap.


Thanks for reading.
