What Are the Reasons for Failing to Jump-Start a Battery?

[JourneyRose]

The reasons for failing to jump-start a battery are: 1. Incorrect connection of the positive and negative cables; 2. Battery malfunction. The maintenance methods for a battery include: 1. Avoid parking the car in an open parking lot for extended periods to prevent the battery from freezing and getting damaged; 2. In winter, car engines are harder to start, so each attempt should not exceed 5 seconds; 3. Regularly charge the battery by starting the car periodically to ensure timely charging; 4. Clean the battery terminals periodically and apply specialized grease to protect the wiring; 5. Avoid using car electronics after turning off the engine, as using the battery alone without the engine generating power can cause damage.
