Thanks Alax/John. i'd spotted some info about the white Varta's whilst googling for the location earlier, i'll check on that, I intend to keep it hooked up to a 500mah maintainer whilst its in the garage just to keep it topped up as from experience the alarm/immobiliser drains batteries when parked for long periods, I used to keep my Mitsubishi GTO hooked up to the same thing (best £5 I ever spent from Amazon) and it was always ready to go.
