talking of the battery, I think mine is on its way out... as about 10 minutes radio use, whilst the car is parked and not running, then it seems to find it harder to crank..
what battery are people recommending nowadays? Not hijacking the thread, as OP may have a similar question soon...... thanks

optima yellow top seems to be the prime choice. Not sure what a good price is but I think I saw a whiffbits advert on here for £160 (possibly plus VAT).
Although I suspect a larger capacity halfords battery would still be fine and that would be less than £100 for their top of the range.
I noticed on another thread the OP has a 59 reg car meaning it's the smaller batter. Not 100% sure but I suspect the bigger batteries came in for the MY12 cars onwards.
I think battery upgrade should be a standard consideration now for those buying the 09/59/10 cars.

I'll be swapping my 59 out soon, last winter it really struggled.
A cheaper alternative to the Optima is this - Exide Premium Battery 156 4 Year Guarantee - Not exactly the same specs but at half the price it's a close match to the Optima's performance for a lot less money.

Chris fitted one of these to my Evo recently and it has made the world of difference - I guess I'll find out for sure when I get back from the Euro Tour ... I used to leave the car 3 days & it would be flat but now it can be left longer (plus it cranks better as well :thumbsup

Sorry if this seems a stupid question but when you say "dead" do you mean it won't turn over at all or the lights on the dash don't even appear?
Its not tracker/immobiliser related is it? Not sure if the stunts they pull immobilising cars willy nilly does the starter motor or fuel pumps. Faulty immobilise or tracker?
Just a thought......batteries do seems to have a 3 year life to be honest so probably that. They do really weird things when not working properly and trying to work out what's going on is hard as its usually random. Change the battery, all problems go away. Seen it loads of times including both the GTR's I've owned.

Tried sticking key in the slot under dash.
it just wont fire up. When jump leads are attached all the lights come on on danotification sering unlocks but she wont fire up.
Is there a way to reset the immobiliser or something. the press brake to start light doesnt come on either. But all other notifications seem to work

If you have jump leads attached and the vehicle that is supplying the power is running as well, give it 3-4 minutes then hit the starter in yours.
If no starter motor action, I doubt it's the battery. I think more tracker or immobiliser issue.
Even if the battery was flat, with the other car running and 3-4 minutes of charging, you should have enough power to spin the starter.

Car does fairly long journeys.
Been on jump leads now for about 30mins.
nothing..... she wont fire up, yet the red immobiliser light near the windscreen goes out.
Can cobra trackers screw around with the car starting?
cant understand why she fired this morning but not now.
would size of jump leads effect
