If the (Auxiliary Battery Malfuntion) appeared in the instrument cluster. It means you need to change your Auxiliary battery. About the main Battery. If you start the Engine in the morning and you feel Hesitant to start I suggest to scan your vehicle and if you see some fualt with low voltage or power management I suggest to change the main Battery because if you don't change and you ignore it will give you a big problem in your Car. Pls. change original Battery AGM.
