To start an automatic transmission car with a dead battery, follow these steps: 1. Use jumper cables by connecting a vehicle with a normal battery to the dead one, linking positive to positive and negative to negative terminals; 2. Start the vehicle with the normal battery first, then attempt to start the car with the dead battery; 3. If the car still fails to start and the battery remains dead, it may indicate that the battery has reached the end of its lifespan or has an internal fault preventing it from charging properly. In such cases, the battery needs to be replaced, which can be done by calling for roadside assistance. A car battery, also known as a storage battery, converts chemical energy into electrical energy. There are several types of car batteries, including conventional lead-acid batteries, dry-charge batteries, and maintenance-free batteries.
