Hi all, from this chain of events can anyone work out what may be the issue?
1) Couple of weeks ago, due to leaving a cig lighter gadget 'on' all night, I woke to a flat battery.
2) After jump starting the car, I went for a short drive, to give the battery some life.
3) Next day (and this time nothing was left 'on' overnight) the battery was flat again.
4) I went to a tyre place and asked them to check the battery for me, they did and the test showed that the battery (it's only 18 months old) was working fine. The guy told me to take the battery out and trickle charge it all night to get a fuller charge.
5) I bought a charger from Halfords and did the above. Stuck it in the car, and it started first time. Great.
6) The next couple of days all went fine with the car starting with no issues.
7) Yesterday I went out on a VERY long journey, and after all that I fully expected the battery to be finally fully charged, and expected no further issues.
Today ....FLAT. Nothing has been left on in the car overnight, so why? Althought its a 2004 car, It's done around 64k miles so is something failing?
