See my post - you have to look at the battery to know (it will say AGM). Some 1Ms have the AGM battery and some don't - I think the later builds did. |
Mine is a later build but dealer replaced under warranty so not sure what came with it but it is not an AGM. So I can confirm some have AGM some don't.
