i'm not following the queston.
yo have a 6v 8n and want to put a 12v battery in it?
have you converted to an alternator and a new style 2.5 ohm coil or added a resistor.. or are you just wanting to cram a 12v bat in there and hope it doesn't burn something up????
here's a battery chart. see what matches up. ( many will ).. of the ones that will.. call around see what's stocked locally.. and of what's stocked. se what's best price.
