Cheers for the replies guys ,

Should have said earlier its for a E60 M5 .... only reason i mentioned about the bigger engine 5s etc is i know somtimes the bigger spec cars saometimes get bigger batterys to run all the gadgets ( maybe iam wrong )

Yea ive become very aware of the "AGM" type that seems to be the thing to put back in the car

does anyone have the ppart number off a S6 AGM Bosch ??

i have a contact in Bosch ireland so if i could get the part number iam pretty sure i could source it through thive had Yuassa in motorbikes before but maybe iam a brand slut but id tend to stick to Exide or Bosch

the car is about to go in for a full service so can get it coded during that pit stop
