The reasons why the dash cam battery cannot hold a charge: 1. Not recording in standby mode; 2. Too many locked files on the memory card preventing overwriting; 3. Poor power supply connection; 4. Built-in battery is depleted and needs charging in shutdown state; 5. System file issues, requiring a system reflash; 6. Power supply problems. The dash cam, also known as the car black box, can record images, sounds, and other relevant information during driving. After installation, it can record the entire driving process's video and audio, providing evidence for traffic accidents. It can also be used by road trip enthusiasts to document their journeys and prevent fraudulent claims in today's society.
When I drive for long periods, I often encounter issues with my dashcam battery not holding a charge. Typically, the battery degrades over time, naturally losing its lifespan after two or three years of use. Improper charging can also be a problem—for instance, prolonged use may cause internal breakage in the charging cable or dust accumulation in the charging port, leading to poor contact and incomplete charging. In hot weather, the car interior can feel like an oven, accelerating battery degradation, while cold temperatures reduce performance. Additionally, poor firmware settings, such as an overly power-hungry parking surveillance mode, can drain the battery quickly. I recommend regularly checking the battery status and avoiding letting it fully discharge before recharging, as this can extend its lifespan. When purchasing a new battery or charging cable, opt for original or reliable brands to avoid issues with cheap alternatives. Whenever possible, park in shaded areas to protect the battery from direct sunlight, ensuring better performance.
As someone who enjoys tinkering with car electronics, dash cam batteries losing charge is often due to charging system malfunctions or environmental factors. For instance, unstable charger output and voltage fluctuations can damage the battery. High temperatures cause electrolytes to evaporate faster, affecting storage capacity, while low temperatures reduce chemical activity. On the hardware side, internal battery short circuits or aging electrodes increase resistance, leading to faster power drainage. Firmware bugs may also cause excessive background process power consumption. My recommendation is to use a multimeter to test voltage—if it drops sharply, replace the battery promptly. Upgrade to a dash cam with a supercapacitor or enable power-saving mode to reduce reliance on lithium batteries. Regularly clean dust and inspect wiring for integrity to prevent issues proactively.
