Hi again,
Yeah I have a 240v to 12v converter for a mains supply, but about half the meetings I did indoor last winter did not have any available sockets, hence why I want a 12v battery.
Can't do a gennie, it won't fit in my car, and also can't use them indoors!
Have got a maintenance charger for it, but not sure if its working cos it doesn't like my old 12v battery (which was a half size formula ford race battery!)
So about £50 - £60 is reasonale for a price for a 75A/Hr Batt? What is the difference between leisure and car battery!?
