Mate, after many years doing DIY servicing the most important thing I learned was knowing when to throw the battery away! 4-5 years from new. Anything more than that is a bonus. In car electrics you need to start with a known good reference point - the battery! I've seen so many people, including myself, try and convince themselves, and others that they can save 50 quid. They charge the battery, fine for a while, and just at the most inconvienient time the battery lets them down again. Even if replacing the battery doesn't fully clear the fault, it will be money well spent knowing that you will have a reliably starting car for the winter.
I spoke too soon.............nothing now! Was just gonna go and give it an hours run in daylight and this!
I think I have to get a new battery from Halfords asap and see what happens from there. This car is becoming a pain in the ar$£ tobe honest with you. Now I know why father in law gave it to me....since he has I have had 4 x new tyres, a steering wheel pump(?), leaky gearbox and now battery/starting problems and a service plus it's due MOT in Feb - can't wait.....think if it gets thru that I will try and get rid. For a car thats probably worth 700 squid its cost me about 500 upto now, must be mad.
Father in law doesnt know how old this battery is although he 'thinks' about 3.5 years.
Cheers
Anyway,
