The Boulevard M109R is a motorcycle where the battery changed mid-run: 2006 takes the YTX12-BS and 2007 to 2014 the YTX20CH-BS. The plate above names the source for each year, and the table shows every run we have on file, so match the year to the case before you order.
For 2007 to 2014 that means the Antigravity ATX12-HD RE-START: 480 cranking amps, 3 pounds, the same case in lithium. Its RE-START function puts the battery to sleep before a parasitic draw can drain it, then wakes it with one press for a jump start. Some trims of this model take a different battery; check the code on yours. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.
