Best way of keep battery charged over winter?
My battery appears dead after six months of no use. The van it was in did have an alarm which I guess has run it down. I've just spent 2 days on ehu and the battery is still dead. Will a proper battery charger resurrect it or do I need a new battery?
If I get a new battery what's the best way of ensuring this doesn't happen again? It's now in a new van with no alarm so will it no longer be an issue as nothing's draining the battery?
caravan is in storage so my choices would either me take the battery out the caravan and bring it home. I'd have to buy a charger and find somewhere to store it all which might be a problem.
Alternative is a solar panel but I cant afford the expense of having it fitted to the roof and don't have the DIY skills to do it myself. So realistically I could only put it in the front window. I've read conflicting reports about whether it would get
enough sun.
battery is for ehu failure only. we always camp with ehu and don't have a motor mover.
