There is something draining your battery if you have a light under your bonnet check to see that it is not staying on, also all other lights,also the light in the boot that it is not staying on, if you can't find any problems there you probably have a short circuit somewhere look for any bare wires around the engine or for a wire rubbing on something, this may be easier when it is dark to see any sparks just give any wires a shake and see what happens....hope this helps.....cheers

What does it mean when the battery light comes on for my 2001 chevy Tahoe?

Usally it means that the alternator is not charging.Check the voltage coming out of the alternator with the engine running.It should be 13-14.7 volts and if its less than 13 volts or more than 15volts then replace the alternator.If alternator test good then check battery voltage you need at least 12 volts.

I have a 2001 nissan sentra that the battery tests good, alternator tests good, but will only run for about 20 minutes then slowly dies and the battery has to be recharged, any ideas on the problem?

if alternator and belt are ok, then check the ground for the neagative on batteryor the cable end itself. car running accessories off, then you should have at least 13.5-14.5 at battery! if less then 13 volts with everything off. then alt, or wiring is the problem. make sure battery terminals are clean and tight at battery. take negative cable off battery while its running. if it quits its a bad alternator, if it stays running alt, is ok. check all the fuses and relays, just to be sure. if you think you have a drain on battery. remove fuses and relays one at a time, until you find the one curcuit thats causing the drain. then replace that fuse or relay. do not pull the pcm fuse or other kam-sensitive modules until you have checked the other curcuits. if the pcm is not getting proper voltage, it will die out ! battery could be weak! battery voltage by itself should be at least 12.68 volts this is at 100%. good-day !

Replaced alternator and battery in 2002 Chevy Tahoe. Battery voltage remains between 9 and 14 (leaning more towards 9 and at times falling completely until trucks shuts off)

When you say battery voltage how are you testing it? Are you looking at a gauge on the dash? Or are you physically testing it with a multi meter? If the truck is dying and you recently replaced the alternator and battery I would first suggest you to check all them connections again real good. Snug them all up. Check for corrosion and clean as needed. Did you replace the battery and alternator with new/re-manufactured battery and alternator? The alternator needs to put out at least 13.6 volts to charge your 12 volt battery or the battery will not maintain a charge. However the alternator runs the vehicle once it is started. The battery is used only to start the car and then the alternator runs it. So if your vehicle starts and runs and then dies you may have a bad alternator. Check your connections first and then test the alternator with a multi meter. Anything less than 13.6 volt will not suffice. 14+ volts would be the hopeful output of a good alternator.

My echo 2001 car battery died, we replaced it the next day and it died as well. We had our alternator checked and it looked fine. The car runs fine after it has been jump started but dies when it is turned...

Check the battery cables at both ends. There's a good chance there's corrosion preventing the charge from the alternator from charging the battery. If the cables are fine then check the connection at both the solenoid and the alternator and make sure they are clean and grounded.

My 2001 Tahoe will not stay running when I give it

I have a 2K1 Tahoe that was doing the same thing. It wouldn't idle properly and would die at stop lights. The check engine light would come on once in a while for a few seconds. I took it to a dealer and they removed and cleaned the soot like residue and other build up from the throttle body. That fixed the problem and I haven't had any problems since then. Hope this helps.
