so that charger won’t work?.. okay, is there any other way to know if its good or dead? i don’t wanna buy a charger right now and try to charge it, but its not gonna work. so i trying to say is, is there any other way to charge the battery without buying a charger? or see if its already charged???????????You need a 2-10amp 12v car battery charger to jump the engine. That will charge your battery but not start the bike, all the ones I got with my bikes are low amperage 8 to 10 hr chargers, trickle chargers. Your max charge is 3/4 of an amp.
