E350
Group Size AUX14 AGM Minimum Cold Cranking Amps170 (i think my original battery has it as 200 amps) You can buy from autozone, advance autoparts, kragen auto parts, mb dealer, napa, etc.
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.
