Yes i have a CTEK MXS5 (cost me £65!) trickle charger! I'm going to fit the battery again tonight and see what i get now that the car has had no power for around 24 hours..
Not having any power for a long period of time should reset the warning lights and engine lights correct?
Thanks Tom, great information!
