its probably a daft question but .. I've just gone to have a quick blast out on the old girl and I've got a flat battery
that's what you get for not using for 2weeks and having a datatool alarm .
Anyway I've got a fully charged 600 battery and while I don't want to use it to start the old girl (which I'm assuming it won't ) I don't want to leave my pride and joy at mercy of the thieving Essex oiks while I'm charging the thou battery for 8hour, Does anyone know if the 600 battery is ok to put on just to run the alarm ??
