going to have to use CTEK on more regularly as not done this before as always.started first time after 3/4 weeks away. Then have put ctek zone for a few hours before taking car out for first run after getting back from the holiday
The battery is 2 and a half years old and make same as originally fitted
Always double lock but going down to Independent later this week to get advice and battery check . Don’t know if he can check battery drain but will ask as he has all the gear!
