Fixing a dead battery yourself is straightforward. First, use a multimeter to ensure it's truly dead. If it is, you'll need to jump-start it using jumper cables and another vehicle with a working battery. Connect the positive (red) clamp to the positive terminal of the dead battery, and the negative (black) clamp to the vehicle's frame (avoid the negative terminal). Start the working car, then try starting your car. Once started, drive for at least 20 minutes to recharge.
