Shop all Honda ATV batteriesWhy the year matters on this one
The Atc 125M is an ATV where the battery changed mid-run: 1984 to 1985 takes the YB9A-A and 1986 to 1987 the YTX12-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 1986 to 1987 that means the Antigravity ATX12 RE-START: 360 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. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.
