Autozone only sells the H9, 100AH and bimmercode only offers 90 and 105AH for battery registrations. Specifically to the G12 LCI, does anyone know which one to use? Its mixed information in other forums..

I want to replace all my BMW batteries with the Autozones 3 years, and I often replace then right before the 3 years is up, and keep the process going, but not sure how to register the main battery, and then the aux battery under the hood.

Bmmercode only shows an update for battery, and not select which battery, has anyone registered their AUX battery with bimmercode? and if so, which battery size did you select for a 100AH, 105? So weird that folks don't make a 105AH anymore, only BMW or random places.

ALso any of the batteries at O-Reilly or Autozone also do not have Vent Tubes, everyone just leaves them off? or is this BMW's way of overpaying for their batteries.
