Battery Saver for auxiliary battery
I am Looking to change my auxiliary battery (The one behind passenger seat) on my SL550
Do I need to install a battery saver as you do for the main battery to protect all memories and settings
Thank you,
Regards

It is recommended by MB that you disconnect the negative terminal on your MAIN battery before replacing the auxiliary battery. So you probably will want a memory saver device if you wish to preserve your preset's.
