What is draining my battery. its not the battery. i replaced my battery two days ago, however, my car is not starting. it make a funny sound when I attempt to start the car. i have a mitsubishi montero sport.

Sounds as though there is a charging problem with the car. It starts when battery fully charged but when the charge is low it fails to start. I would get a mechanic to connect his meter to the battery and see if it is charging as it should. It is also possible that something is draining the battery when not in use. Check interior lights are going out when parked up, nothing is plugged into cigarette lighter outlets attached to sat nav etc., things like that.

I think it's doubtful that your starter is draining the battery. Once your starter is engaged upon start up, it is done with its job, and it is not needed until the next start up. It does sound like your starter is going bad. If all of the electrical parts seem to come on when you trying to start it, it should have plenty enough juice to start it. One possible cheap solution is it could be the starter relay. The relay takes power from your battery and routes it through to your starter. If this isn't working, your starter isn't even getting any juice. I hope this is the problem. I have seen many starters replaced that should not have been because fo a bad starter relay. You would have to Google that info on a Monte Carlo. I could not tell you where it is on any Chevy.

Yes one of the relays could be draining the battery.
I would open the fuse and relay boxes and try to find where the noise is coming from. If it is a relay, pull it out and see if the noise stops.

Yes,the newer cars need a strong battery or funny things happen. You'll need to replace your brake pedal switch or bleed the system properly. don-ohio (:^)

Hello, sounds like you need a new battery. As the battery goes flat the alarm senses it and sets off the warning system. Try changing the battery first and test it during the day. Also check to see if there is anything draining the power. You may also be able to adjust the alarm settings manually. Failing that, the alarm may need replacing. I hope I have helped.

Battery is dead ... dropped a cell ... get a new one ... the cold weather is hard on poor old batteries

Sounds like a battery to me. The cold doesnt drain the battery it just makes it more difficult to produce enough energy to crank the car. If the battery is weak already, the cold just makes it worse. Replace it and move on!

The funny sound you mentioned must be identified, could it be the starter trying badly to turn. Here the fault of your battery drain is that the glow plugs take a lot of current and it must NOT come ON when the starter motor runs. Hence the fault could be your GLOW plug relay unit with the auto cut off timer that is faulty. If you keep draining the battery to a lower threshold level , there is every possiblity that the battery life will be lowered . I hope the present battery rating is the recommended Amp/hr rating to give the extra run for the morning start. Next area of suspicion is the starter motor itself , it could have a bad commutator or a bush. It will be good to have a clean up and service. Finally check for excessive drain on your battery with a current check in series for the drain current when the switch if off. If the current exceeds the limit disconnect each circuit to confirm. hope this advice helps. good day

there is an open cirket somwhere draining the battery

sounds like its wired up wrong, remove the radio unplug the connector and remove the radio, then check all your fuses must have blown one when radio was installed, after that charge battery and with radio removed see if battery goes dead, if not recheck wiring to radio, common problem with vw aftermarket radio,they are installed wrong,good luck,
