Why did the battery of the Baojun 730 suddenly run out of power?
4 Answers
The reasons for the sudden power loss of the Baojun 730 battery may include insufficient charge, battery aging, or vehicle leakage. Below is a detailed introduction to the Baojun 730: 1. Overview: The Baojun 730 is a 7-seater family car customized by SAIC-GM-Wuling for 'Chinese extended families' based on the needs of millions of users. It was officially launched in March 2019, including two models: the 1.5T-CVT Fashion and the 1.5T-CVT Flagship. The vehicle offers high driving smoothness and comfort. 2. Others: The vehicle dimensions are 4780×1820×1755mm. The trunk capacity is 261 liters. The fuel consumption ranges from 6.3-8.0L/100km. The fuel tank capacity is 52 liters. The engine type is a naturally aspirated engine. The standard seating capacity is 7. The top speed is 160km/h. The acceleration time is 18 seconds (0-100km/h). The vehicle weight is 1410 kilograms.
I've been driving for over a decade and have encountered the issue of dead batteries in my Baojun 730 multiple times. There are several aspects to consider. The most common cause is battery aging, especially with the original factory battery which typically lasts only three to four years before failing. You might not notice the gradual voltage drop while driving, but after parking overnight, the car won't start. The charging system also plays a role—if the alternator malfunctions, the engine runs but the current doesn't charge the battery, particularly during cold winter starts when battery performance is worse. Forgetting to turn off lights or devices like dashcams can drain the battery too; once, I left a charger plugged in overnight, leading to trouble the next morning. Good habits to adopt include checking all electrical devices are off before shutting down the engine, regularly testing battery voltage at a repair shop, or keeping a spare battery for emergencies. Long-distance driving or frequent short trips can also harm the battery, causing sulfation and failure. In short, if you notice an issue, don't push your luck—get it checked by a mechanic promptly to avoid bigger problems.
As a young driver who frequently uses the Baojun 730, a sudden dead battery can be really frustrating. Let me share some practical insights. It could be that the battery itself has reached the end of its lifespan, especially if you frequently take short trips that don't allow the battery to fully recharge, leading to a gradual depletion of power. Charging system failures are also common—issues with the alternator or voltage regulator can prevent the battery from fully charging while appearing normal on the surface. Modern car accessories like phone chargers and parking monitoring apps running in the background are hidden culprits; a buddy of mine experienced frequent battery drain after installing a new navigation system. Wiring shorts are another issue, often caused by improper installation of aftermarket alarms or audio systems. Here's how to check: use a multimeter to measure the battery voltage—if it's below 12V, it's likely beyond saving. Keep an eye on dashboard warning lights as well. Preventive measures include disconnecting all external devices immediately after turning off the engine and having the charging system tested during regular maintenance. Budget cars like these require extra attention to maintenance—don't lose big by neglecting the small things.
Having worked in an auto repair shop for a long time, I've dealt with numerous cases of dead batteries on the Baojun 730. Here's a brief rundown. The primary cause is battery aging, where reduced capacity leads to failure to start. Charging system malfunctions, such as the alternator output voltage dropping below 14V, prevent the battery from charging. A key issue is power leakage—check for aftermarket electrical installations or short circuits, and use an ammeter to measure static discharge; if it exceeds 50mA, leakage is confirmed. Common culprits include unclosed door lights or excessive ECU power consumption. In winter, batteries perform even weaker, often lacking sufficient cold cranking current. Basic troubleshooting recommendations: first inspect the battery for any signs of leakage and measure if the voltage is below 12V; if normal, check the fuses and alternator belt tension. For repairs, it's best to replace the battery outright to avoid recurring issues that could compromise starting safety.
