How to Use a Trickle Charger to Keep Your Car Battery Charged During Winter

If you’re going to store your car for the winter, it’s important to properly maintain the battery so that it doesn’t die. One way to do this is by using a trickle charger. This is a device that slowly charges your car battery over time, keeping it topped off and ready to go when you need it.

The process of attaching a trickle charger to your car battery is straightforward and can be done for any vehicle that you’re going to store for an extended period of time. First, locate your battery. In the case of a 2013 Mustang, the battery is located under the hood. However, some newer cars may have the battery located in the trunk.

Next, you’ll need a trickle charger. The narrator of the original video recommends using a DieHard battery charger and maintainer, but you can use any brand you prefer. The charger should have three lights: one to indicate if the clamps are reversed, one to indicate when it’s charging, and one to indicate when the battery is fully charged.

To attach the trickle charger, first, make sure the clips are marked positive and negative. Clamp the positive clip to the positive terminal of the battery and then clamp the negative clip to the ground. Once both clips are connected, plug the connector into the battery tender itself.

Check to make sure the charger is working by looking for the indicator lights. The orange light on the narrator’s charger indicates that the battery is charging and will likely take a day to come up to a full charge.

After both clamps are connected, make sure they’re both underneath the hood so that there’s no contact with anything when you store your car. The narrator recommends storing the car with the hood closed or mostly closed to keep rodents out.

Finally, route the cable down and around to the front of the car where the maintainer is sitting. And that’s it! By using a trickle charger, you can ensure that your car battery stays charged throughout the winter months and is ready to go when you need it again.
