The solutions when the car won't start due to a dead battery are: 1. Replace the battery; 2. Check the engine's working condition; 3. Add electrolyte to the battery; 4. Inspect the wiring and fuses for faults, and replace fuses promptly if needed; 5. Apply conductive paste on the battery terminals; 6. Push-start the car. Methods to check if the battery has power include: 1. Check the battery's charge indicator; 2. Measure the battery's static voltage; 3. Look for the battery warning light; 4. Observe if the dashboard flickers or dims when starting the car; 5. Check if the battery shows signs of bulging, deformation, oxidation, or leakage.
