I'm thinking on my feet here having asked the same question of myself and my conclusion is that it has to be similar to jump starting a car - your'e battery being charged by another cars' til you start up, run the engine for a few minutes then take the jump leads off. The alternator will take up the chrging role once the engine is running so there just isn't any need to stay hooked up as well and the battery isn't gonna know or care where its charge comes from and then pick a favourite so there isn't much point unless you are sure your battery is flat - like mine 'cos its got sooo cold out there. As for leaving it on constantly - I was told that batteries are better charged then used then charged than just kept topped up but I fear that a battery expert somewhere will be shaking his head and give a good tecchie explanation about that. In summary I dont think it does any harm but there isn't really any point.

So I have given up working out how to sell my boat curtains, or how to get last of the water out of the hull after my pump leaked, and have taken a bike ride from fazeley to Atherstone via the towpath. Aaaagh it's horrible and bumpy and full of little gates that slow you down and so I came back on main roads much quicker. Anyone know any decent routes to Coventry 'cos I don't want to towpath that far but don't fancy the A roads either? OOh this spring weather is just lovely
