As the subject says. The battery is not my problem, I have taken it in, and the mechanics say that no wires (covered or exposed [if there are any]) are touching anything. So, they told me it's the battery when I have already replaced the battery 4 months earlier. I do not know what else to do. I do not want to keep spending money on a new battery every time. What else could it be?

Hi,

If the battery keeps failing, it is one of three problems. First, as you already mentioned, the battery is faulty. If you question this, charge the battery and have a parts store load test it for you. Most do it at no charge. If it does fail the test, it should be replaced for free if it is only 4 months old.

Next, if the battery is failing overnight when the vehicle isn't used, then we have a parasitic draw. In other words, something constantly is draining power even when everything is turned off. Here is a link that will help with that concern.

If the battery fails while you are driving, then the alternator is the most likely cause. Again, you can have a parts store test the alternator free of charge. Or you can check the alternator at home to determine if it is charging. All you need is a multimeter or voltmeter.

Here is a link that explains how it's done:

I know this may be confusing. Please let me know if you have questions and what I can do to help.

Let me know.
