my hubby has a 2004 tdci 1.8 ghia focus, he works away for two weeks at a time and when he comes back the battery is flat we had a auto electrician look at it and nothing obvious was showing , the alarm and immobilisor are on all the time he is away , would they drain the battery ????? this is the second new battery in as many months , the alternator seems to be charging ok ,it starts every day when he is home after the initial starting with battery boost pack
any help would be appreciated ...thanks
