Whats the purpose of this battery

[@silver750iL]

My 2011 S350 bluetec diesel has a bigger aux battery behind the back seats backrest, no small aux battery. It is a stop/start car. Main battery under hood/bonnet.

[@jebigajohnny91]

i found this bracket that‘s supposed to hold the aux battery but no connectors, nor the battery itself. where could it be? (2011 w221)
