03 vue battery dieing

i have a 2003 vue that the battery is dieing rather quickly just in a few days of sitting around the alternator was tested it works but not sure what to check next just looking for some helpful adive any advice would be greatly appreciated thank you

Have you completely charged the battery? If you can, disconnect the battery and take it out of the Vue. Put a charger on it overnight. With a meter test the voltage. Is the battery fully charged. If so, Let the battery sit for 24 hrs. Test the voltage again, if its less than 12 its time for a new battery. If the battery holds the charge Start looking for either a short/connection thats draining the battery. Could be something as simple as a light thats on but you don't see it, like a glove box light. Or an abraded wire some where.

Alternative is to take the battery in to Autozone/O'Reilly etc and ask them to test it.


Good luck.
