Something is draining battery power before starting...
My Audi 2.8 v6 battery keeps loosing its charge for starting when the car is left for any length of time, but immediately hops back up to 14 volts on the in-car gauge when bump started. The starter motor sounds like its turning with the charge that is left in the battery, albeit very slowly and not fast enough to get the car ticking over. Could this be just a low battery, or something more serious to do with a fault/short in the electrical system or alternator?

Sounds like your alternator might be bad or your engine belt is loose (or broken). If you can get the car started, check voltage at the battery. If you have 12+ volts for at least 20 minutes, your alternator is ok. If you have less, it's bad.
the battery to get drain means that you have a power leak somewhere. Check sometimes the light in the boot still on as the off switch is faulty or the door is not closing it. What to do first remove the bulb for a night and on next day starts fine the repair the fault. Also sometimes light might still on current to a very low power where is not spot as it happened to me on a customer Alfa Romeo 147,having power leak on the rear left light very low currency and how spotted,left in a very dark place and noticed. If you think is rather difficult to do something take it to an expert electrician to check every close reason for power leak.
could be the battery or something draining power from the battery,
when you get home, disconnect the negative battery terminal from the battery,
leave it over night
in the morning connect it and try to start,
if you do not start it means that your battery (although new) has a bad cell thats causing the charge to drain, take it back for warranty. Dont worry about the load test done to check the battery it'f based on the battery's current charge rate not after its left overnight.
If you did start it means something is draining power from the battery, could be,
1.) lights remain on check (hood light, door lights trunk lights)
2.) device remaining on , check radio, ac etc
3.) the cars CPU is draining too much power.
an easy way to check which one is to remove the fuses from the fuse box under the hood for each particular component to turn them off. or you can take the car to a gurage and have them go through all the harnesses for a short.
check that the alternator is able to charge. if the alternator cannot charge the battery, it will go dead. if the alternator is okay, google ´¨finding parasitic battery drains¨. it may be that something is draining the battery even when the key is off.
Car getting started then cuts off after 2 seconds.Its starter related issue.Either the starter is faulty or battery to starter connection is loose or got short in between.It has to be checked and replaced.Get the voltage checked from battery to starter.The battery should show 12 volts if fully charged.
My car is Mercedes E200-1997, I have problem with the electricity. There is constantly consuption of electricity current ( even when I switch off the car, about 20mA. which lead to exhaust (drain) the battery and need charge it for some days!!!
I went to some services but they can not find the out of order!!!
loose belt, if it is worn then it will not keep the battery charged...
loose ground wire or bad ground wire...
possibly bad alternator, not keeping the battery charged enough, that would explain the stalling, and loss of power.. hope this helps you.....
Batteries that go flat is related to Charging Systems that don't Charge or Batteries that can't hold Charge.The clicking is not enough voltage to yur starter.Have someone Jump Start or Tow to Service Station they will use instruments to check status of charging system, battery.A loose belt can cause insufient charge.Good Luck
Faulty batteries are rare. Typically when battery won't stay charged an alternator is needed, but you can check for a current drain first. To do this you need an ammeter. Disconnect positive line of battery and connect the circuit "through" the ammeter instead. (DO NOT START THE CAR LIKE THIS!!!). Monitor current draw - as you do so, pull each fuse from fuse panel (left side of dash). Don't pull them all, but rather remove one at a time. When the ammeter shows minimal current drain you'll know which circuit is causing the draw. You can then disconnect individual loads on that curcuit until you find the culprit. Hopefully it's something easy like a light switch - but it could be more involved.
