Aux Battery Replacement for 2014 E350
Tool:You need a 10mm socket for the 3 screws. I follow this video when I recharge aux battery with my Ctek charger every 5-6 months. Very easy to remove and install as only 3 screws to remove/tighten, 1 hose to detach/attach, and cage to lift.
I don't think there is a memory unlike the main battery. Didn't drive while i had the aux battery removed from the car to test it out.
