Ok I have a dedicated tekken 4 jamma cabinet at home. Love this game . Originally I bought it cleaned it replaced the cmos battery because the one inside would not keep the free play and initial settings and scores . After 6 months the new battery died . I figured I would try another brand this time energizer lithium . Same thing 6-7 moths battery dead again. Next step I purchased another namco system 246 kit also replaced the battery . Same thing battery dead after 7 months . Is there something g else that’s killing the battery like the io board ? Most everyone says the battery should last years . . This is for home use only and gets played maybe once a week . Any help or advise would be awesome thanks
