Because you’re probably going to install this yourself on a possibly modified bike, we can not take batteries back. Second thing to know/check is if your bike has already been upgraded with the right type of rectifier/regulator. The stock ones can be a bit dodgy after 40 years and might fry your battery. Old big batteries have a bit of flex in them. They kinda work like an expansion barrel – these newer type batteries dont have that much room to fuck around.. If you are unsure about anything, contact us BEFORE ordering. If you have a mulitmeter, these batteries can not cope with more than 13.5 on the battery terminals at 5000rpm. 99% of the times you’ll be just fine, but as we want to be honest about everything.. better safe than sorry right?
