Answer 1

your alternator is the problem. not charging the battery when the car is running.

Answer 2

Faulty battery, energy drain, something left on, not charging when running, battery too small for size of engine, needs sells filling up with heavy water (distilled water), battery not fitted correctly to terminals.

Have you taken the battery off the car and proved that there is no charge there? If there isn't, then my bet would be that you have a charging problem, and not a battery problem.

Answer 3

Check the earth connection (where the neg terminal connects to the body) if it's loose or corroded then you'll have no power at all simulating a dead battery, have you checked whether the lights work when it wont start? It might be your starter motor sticking which is why it sometimes starts and then it wont. Hope this helps, good luck!

Answer 4

This maybe because you have a faulty alternator which recharges the battery whilst being driven. Sometimes this is highlighted by the battery symbol light coming on or flickering. This would be the best place to look first.

Answer 5

that is 3 main reasons for the battery to go flat:

1, the wiring on you car have a bad contact some were and makes the battery to lose power.

2, the alternator that charges the battery is not working properly.

3, the battery may have a fault from factory that makes it not to accept charge.

i know there is more, but i think this are the main reasons for it to go flat...

Answer 6

After jump start your car take a small tour and see if it restart then the problem is in the battery.See the battery d-water level.
I think the problem is in the battery and its cell gone weak.

Answer 7

If it is your alternator.. dont buy a brand new one. You can get a reclaimed/reconditioned one by mail order .. see such dealers in the back of Autotrader. It would work out about 25% of the original cost of a new one and usually they come with a short guarantee. You would be unlucky to get a secondhand unit that failed too. They are dead easy to fit too.

Answer 8

this was happening to me and i found out that a small light inside my boot was on so every time i left the car for a long period it would flatten the battery in the day light i could not see that this light was on and i rarely go out at night so it was weeks before i found out hope this helps

Answer 9

start the car and take one of the cables off of the battery with the car still running...if the car dies it is your alternator ..if it stays running you got yourself a piece of crap battery and you need to take it back if you got it from a car parts store so you can get a new one for free

Answer 10

I had the same problem.. and after much tail and error, I found the problem to be a small flashing light on the dash to indicate the immobiliser was activated so i ripped the little bastard out, and I've never had a problem since....

Answer 11

parasitic drain somethings draining it use a test light take the neg cable off and connect it to the battery through the test light if it lights bright u got a drain
