Attaching the terminal to Battery


To charge a dead auxiliary battery, you will need a battery charger and some basic tools. Here are the steps you can follow:

1. Locate the auxiliary battery in your vehicle. It is usually found in the trunk or under the hood.


2. Disconnect the negative terminal of the battery. To do this, you will need a wrench to loosen the bolt that holds the cable in place.


3. Connect the positive terminal of the battery charger to the positive terminal of the auxiliary battery.


4. Connect the negative terminal of the battery charger to the negative terminal of the auxiliary battery.


5. Turn on the battery charger and set it to the appropriate charging rate. Most auxiliary batteries require a charging rate of around 2 amps.


6. Leave the battery charger connected to the auxiliary battery until it is fully charged. This can take several hours, depending on the size of the battery and the charging rate.


7. Once the battery is fully charged, turn off the battery charger and disconnect it from the auxiliary battery.


8. Reconnect the negative terminal of the auxiliary battery to the negative terminal of the vehicle.


9. Start the vehicle and let it run for a few minutes to ensure that the auxiliary battery is working properly.

It's important to follow these steps carefully to ensure the safety of both you and your vehicle. If you are unsure about any of these steps, it's best to consult the owner's manual for your vehicle or seek the assistance of a professional mechanic.
