Aready have a CTEK but need to buy a decent 10am or larger battery charger as found battery flat after 3/4 weeks away - not happened before as when away 3/4 weeks three times a year it’s always started first time and I’ve just used my ctek to boost it up for a few hours before using again
Cannot leave CTEK on whilst away
Car is a 2012 v8 XKR coupe with 26k miles and good Varta battery 2.5 year’s old
thanks
