Nothing at all wrong with the cheap ones, especially the pencil thin ones, if you don't mind the odd bit of melted red or black plastic on top of your wing.


Best way to start from a donor car, correctly connect leads - to engine + to battery + post or jump post.


Start donor car and let it run at fast idle for a few mins depending on how flat the battery is, start the flat car, run this at a fast idle for a few mins till the engine is getting warm, on the flat battery car switch on the headlights or heater on, shut down the donor car, remove leads one at a time, take it a run to Blackpool and back.


Then if there was no obvious reason for the battery to be flat, get it tested.
I will fully charge the battery with it disconnected, check with a volt meter then leave for a few days and try again, I will then reconnect it and test to see how many amps are being drawn.
Whilst it could be a duff battery it does look and I was told is new.

If amp draw is the problem I may well leave the battery disconnected or even remove it and put it on a modern permanent charge to look after it
