What to Do When the BYD Song Battery Runs Out and Fails to Start?

There are two solutions when the BYD Song battery runs out and fails to start: 1. Jump-starting: Contact a rescue vehicle, connect the jumper cables, and temporarily charge the battery through the rescue vehicle to start the engine. This is the correct approach. To avoid being unable to charge when the car battery is dead, always keep a set of jumper cables in the car. When connecting the jumper cables, it is crucial not to mix up the connection sequence. First, connect the positive terminal of the dead battery to the positive terminal of the rescue vehicle's battery. Then, connect the negative terminal of the rescue vehicle's battery to a metal part (ground) in the engine compartment of the dead car. After connecting the jumper cables, start the rescue vehicle's engine and slightly increase its RPM. After about 5 minutes, the dead car can be temporarily charged. Once charging is complete, remove the jumper cables in the reverse order of connection. 2. Push-starting or Towing-starting: In the absence of jumper cables, push-starting or towing-starting is the most familiar and effective emergency starting method. However, this should not be used frequently as it may cause some damage to the engine and clutch, especially for automatic transmission vehicles, which should avoid using this method to start.

I've encountered the situation where my BYD Song couldn't start due to a dead battery several times. It's usually caused by forgetting to turn off the lights when parking or leaving the car unused for extended periods, leading to complete battery drain. My solution is to get a friend's car to help jump-start: take out the jumper cables, connect the red clamp to the battery's positive terminal and the black clamp to the negative terminal, being careful not to cause a short circuit during connection. Wait a few minutes to let the BYD's battery charge slightly before starting the engine. After successful startup, drive for about thirty minutes to recharge the battery. If the battery is over three years old, it might be aging and due for replacement - also check the terminals for corrosion. For prevention: always confirm lights and electronics are off before shutting down the engine; if parking over a week, either start the engine to idle for ten minutes or connect a smart charger to maintain battery level. These simple measures can easily avoid trouble and save on repair costs.

I often help people deal with car issues, and a dead battery preventing startup is quite common. Don't panic—turn on the hazard lights and pull over safely. It's best to find a familiar driver to bring jumper cables and assist with connecting the positive and negative terminals for a jump-start; be cautious of sparks to avoid burns. If no one is available, use a mobile app to call the insurance company's free roadside assistance service, which usually arrives in about ten minutes. After starting, drive around for half an hour to recharge the battery. For prevention: avoid leaving the car idle for too long—drive short distances twice a week to maintain the charge; inspect the battery for signs of swelling or leakage, and replace it promptly if aging. This method is simple, effective, and saves both hassle and money.

When the BYD Song battery is dead and fails to start, first check if the headlights or horn are working properly to assess the power level. Using a portable jump starter is the quickest solution: connect red to red (positive terminals) and black to black (negative terminals), ensuring secure contact to avoid shorts. After starting, monitor the dashboard voltage display—normal readings should be above 12.6 volts. If unsuccessful, it may indicate a relay or charging system issue; visiting a repair shop for diagnostic trouble codes is recommended. Prevention tips: Install an in-car voltage monitor with an alarm; regularly measure battery health to maintain a full charge.

I use my BYD Song to take my kids to school. Once, when I returned from a business trip, the battery was dead and the car wouldn't start, which was really frustrating. The reason was that the car had been parked for two weeks without moving, and the battery drained completely. Solution: I immediately called my husband to help jump-start the car with jumper cables; after connecting the cables, we waited a short while and successfully started the engine. If that didn't work, I would have taken a taxi to the supermarket to buy a new battery, which costs around 200 yuan. After starting, drive to a charging station or go for a spin to recharge. I've learned my lesson now: always check all switches before turning off the engine to avoid leaving anything on; if the car is used less frequently, start it once a week and drive for about ten minutes to maintain the battery. Paying attention to details in daily life saves a lot of trouble.

Don't panic if your BYD Song runs out of battery, prioritize personal and vehicle safety: Pull over to the roadside, turn on hazard lights to avoid obstructing traffic. Contact family or roadside assistance with jump-start tools, always wear insulated gloves during operation for safety. After jump-starting, observe if the battery light turns off indicating normal charging. Common causes include forgetting to turn off lights or aging battery leakage. Preventive measures: Avoid parking for over a week; Keep a portable jump starter in the trunk; Annual maintenance to check battery health and replace when necessary for safety. Sharing this experience helps reduce unexpected risks.
