Why does the battery of Fengguang 580 always run out of power?

The reasons why the battery of Fengguang 580 always runs out of power: battery leakage or battery aging. Dongfeng Fengguang 580 is an SUV under Dongfeng, with body dimensions of 4690mm, 1845mm, and 1715mm, and a wheelbase of 2780mm. The lifespan of a car battery is related to various factors such as the condition of the car, road conditions, driving habits, and maintenance status. The Fengguang 580 is equipped with a 1.5T start-stop technology engine, paired with a 6-speed manual transmission, and the cabin space can be freely transformed between 5-seat and 7-seat configurations. The Fengguang 580 uses two types of tires, 225/60r17 and 225/55r18.
My Fengguang 580 also frequently has battery issues, likely due to multiple overlapping factors. The battery itself becomes prone to failure after two years of use, as sulfation or internal short circuits in the plates can cause power loss. The vehicle's charging system might also malfunction—for instance, low alternator output voltage or a loose belt can prevent full charging while driving. Another major issue is parasitic drain, where devices like my dashcam or audio system aren't fully turned off, or faulty door contacts cause leakage, silently draining power overnight. Frequent short city trips exacerbate the problem: engine starts consume significant power without sufficient driving distance to recharge the battery. This worsens in cold weather—last winter, I often faced starting difficulties. These factors interact cumulatively. I recommend first inspecting the battery for corrosion, checking if its resting voltage drops below 12V, then visiting a professional shop to test the alternator and electrical circuits to ensure safe operation.
My Fengguang 580's battery keeps dying, which is really annoying. Common causes include the battery reaching the end of its lifespan—replacing it should solve the issue—or a faulty alternator rectifier leading to low charging efficiency. Improperly installed aftermarket electronics like backup cameras can also drain power when the vehicle is parked. If you're only driving short distances in the city every day, a few kilometers back and forth simply isn't enough to recharge the battery. Large temperature variations accelerate battery aging—last summer, the car wouldn't start with the AC running. A quick check of fuses and wiring connections for looseness is advisable, and a charge-discharge test may be necessary if needed. Regular maintenance of battery terminals and avoiding deep discharges can extend battery life.
