   I'm trying to help a young chap get a coil ignition Scott going. It's a 6v system but we dont know what sort of amperage the battery needs to be. Can anyone help please? Thanks.

	I doubt it's crucial. Any motorcycle 6v battery will suffice. Not as if you have a starter motor.

	Thanks, Brian. It's not something I'm an expert on. I'll pass that on, much appreciated.

	Jerry, 2 of my British bikes are still on 6v, admittedly with magneto ignition but I don't think coil use will be different. With coil ignition though you will need to ensure the charging circuit is working ! Typically I go between 4-6Ah. Size is more critical to me as they are hidden inside a dummy Lucas rubber battery .... I have just bought one of these for my '54 BSA B33:- https://www.bblbatteries.co.uk/product/gel-fulbat-m-cycle-battery-6v-6ah/ Cheers, Adrian Bristol UK Edited by AdrianW - 09 Mar 2026 at 08:10

	Something like that would be ideal.
