The Ninja ZX-6 is a motorcycle where the battery changed mid-run: 1990 to 1992 takes the YTX14AHL-BS, 1993 the YB12A-A, 1994 to 2003 the ATX12-AH and 2004 the YTX9-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 2004 that means the Antigravity ATZ-10 RE-START: 360 cranking amps, 2.6 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.
