    Dead Battery?

    My car has been sat on the drive now for about 3 weeks as i've been waiting to get money for new EGR valve and other bits. Yesterday the remote central locking worked twice and then wouldn't work.

    I tried to start the car this morning and all dash lights light up but then when attempting to turn it over only the battery light shows.

    Does this mean my battery is bushed? (should a battery discharge when not in use), only thing being used battery wise will have been the alarm flasher thingy on the headunit.

    My old cars battery died after just over a week of not being in use. Didn't have an alarm or anything so I'm sure your car battery will have done the same.
    Try getting a battery recharger or it might need replacing completely.

    well that's what i was wondering, is the battery knackered. I want a diesel battery really, something with a bit more power, what power rating should i look for in a new battery though?

    Money won't permit new battery at the mo, just got two new tyres, new EGR valve and front anti-roll bar link, so i think i will have a shot with a battery charger for now anyway

    I fitted a Bosch S5

    74 AH / 750 CCA

    They're not cheap but the starting performance is excellent even after a couple of days outside in the recent -9 weather. It might be overkill for a 1.8 petrol but I'd rather have too much juice than too little.

    Should stick to a battery that is rated for your car as a higher powered battery can damage your car's electrics.

    Forgot i'd started this thread, but now i'm looking into a new battery so hey. Is this true, as i've heard on numerous occasions of people fitting diesel battery etc with higher power output?

    no it can't. incorrect voltage or too low a rating may be detrimental
