Hi all , would love some assistance from all you wonderful people. About 3 months ago my battery on the Stilo went flat (it had been standing approx 2 weeks) so after a jumpstart off it went. The car was used constantly for the next month without any hiccup. I parked it up on the friday night and when I went to it on the sunday it was dead again. Again a quick jumpstart and off I went.
I had no problems for about a month until it was due for MOT , went to start it on the morning of the MOT and nothing. Jumped it and got it to the test centre where I told them what had happened. About an hour later had a numpty ring me to inform me my battery was flat. I explained what had happened and he said he would get me a new one because there must be a problem with it ( I hadnt changed it in the 3 years I have had the car) . Been driving it now for 3 weeks without a problem and parked it up thursday eve, Went to it this morning DEAD as a dodo. I know I switched the radio off way before I got home and the lights were switched off. Now apart from the alarm I cant think of what can drain it but dont think the alarm would drain it in 36 hours. Any ideas ? My thinking is alternator but surely it would have gone flat quicker as most of my journeys are short. Up until 3 months ago I have never had a problem and have not fitted any extra electrics to it

I have a 1.6 Dynamic, thanks for the help I will test to see if there is any drain then bite the bullet

what stilo have you got?
i have a 1.2 and i fitted a heavy duty diesel battery i think its a Varta.
you test your alternator i would let the car run and get an amp meter on it, your battery should got from 12v to around 14v to show a healthy charge

Thanks for your help , I will use my multimeter on it and see what happens but gripping the seat tightly waiting for the cost of an alternator lol

The regulator i think is the bit that causes the problem? New alternator sorted it out for me.

I suggest using a multi meter to see if you have a drain on the battery.

Just to thank you all for your help and to update the outcome. I took it to a local company to check the battery out and they said the battery that was installed by the garage was not man enough for the job. I had a new one fitted and have had no problems ever since. The garage that initially fitted the battery refunded me the money after I had given them the battery they installed back
