Why does my car battery discharge after charging?
It’s possible you have problems with the battery itself (see the “state of charge” table below). Charge the battery and repeat the test. If you get the same readings (and problems) after charging the battery, you may want to take the battery to a shop for a battery load test. This is one of the best ways to confirm battery condition.
Why does my Chevy Silverado battery keep dying?
A considerable number of drivers have said the battery on their 2007-2013 Silverado or Sierra dies frequently. This could be caused by problems with the battery or other issues that cause the vehicle to run the battery down.

What to do if your car battery won’t charge?
So let’s find out why your car battery doesn’t hold a charge. Inspect the battery. Do a battery terminal test. Clean the battery terminals. Do a battery voltage test. Do a quick charging system check. Check for battery leakage (and fix any leaks). Do a battery drain test. Perform a hydrometer test. Do an alternator diode test.
What to do if your Chevy truck is running out of battery?
Remove the bolts and clean the bolt threads and the ends of the wire attachments and clean down to the frame using a wire brush. Reattach the wires to the frame. Pull out the dash’s outer trim far enough that you can reach in and pull out the old switch. Push the trim back into place. 4. Frequent Battery Rundown
What should my car battery charger reading be?
If you get a reading between 12.4 and 12.6, your battery has a good charge. If you were suspecting a battery problem because you had difficulty starting the engine, or you had problems with another electrical circuit, or the alternator warning light on the dashboard is coming on (charging system problems), your problem is not with the battery.
What does a fully charged car battery look like?
A fully charged battery will result in a reading between 1.265 and 1.299 of gravity across all cells. The lower the gravity reading, the lower the charge. A discrepancy of between 25 to 50 points between any two cell readings would indicate a ruined battery. Hydrometer results are a general indication of the state of health of your battery.
How do you remove a negative battery connector?
If the cable is seized to the battery post, a special battery cable removal tool may be needed to remove the negative connector. Ask your local auto parts store or mechanic. Follow the same procedure to disconnect the positive terminal. After removing it from the terminal, don’t let the positive connector touch any metal part of the car.
Why does my ATV battery keep losing charge?
To test if your battery holds a charge, simply disconnect both terminals and fully charge the battery. Use a multimeter to measure the voltage. If it still loses its charge over a day or two, you likely have a bad battery. Notice that this behavior may be due to internal sulfation, which sometimes can be fixed.
