Hi everyone i plan to replace my car battery on my MAZDA 6 2.5 petrol automatic year 2019, can someone please confirm, do i need Car memory saver or not? Can i replace my battery without car memory saver , i dont want to visit dealership to re-learn things etcs if its not possible and i will loose some stuff and i need relearning or education or modules please tell me , also in case i need memory saver can i use brand new car battery 12v and connect from new battery to the car battery terminals during replacing my car old battery with new battery ? - this service battery will be 3rd it will be used only to supply some electricity during the change please advice.

 

The minor setting lost are easily readjusted. There is no operating system that will be compromised for the battery change. The use of a memory savor is not required.
