Fully charge the battery then have it load tested (most part stores will do this free) . if it checks good have the charging system tested ( Altenator & Regulator) . if this test is good then you have a draw ( something useing power while the system is off ) . a simple test can be done to check this . remove the red + wire from the battery conect a 12 volt light to the red + wire and to the battery termnal turn off all knowen switches , close all doors and check to see if light is on if so start pulling fuses till the light goes out that will be your drian ( draw ) .. good luck .
My car is a 2007, battery died the other day, jumped the car now it's fine. How long until it dies again? Or should I just replace the battery?
If you haven't already take the battery to a parts store and have them put a load tester on it. If the battery is good you'll want to take the alternator for a test,. Hope this helps.
Re-charge the battery with an external battery charger, not another vehicle. Have the battery load tested and have the vehicles charging system checked. You have one of three problems: a bad battery, a bad alternator/regulator or s component that is drawing power when vehicle has been turned off. usually it is one of the first two items.
There is a defect in the charging system...battery juice that is being used is not being replaced. This is typically caused by a faulty alternator or voltage regulator. Take the car to an autoparts store and have the alternator tested. Most parts stores will test the alternator at no charge. If the alternator is defective it will have to be replaced. Hope this helped you. Best wishes.
