Sort of it is not a very good video to be honest , would I actually have one and what does it do ?
I know if my main battery is disconnected the clock etc does not save the time

The auxiliary battery helps to run the vehicles accessories and on newer models the stop/start function. It’s normally located in the footwell near the fuse box. I am unable to help you as to whether your particular model has one but I’m sure someone will be along soon with further advice. A good trawl through the Internet sometimes gets results
