1. Dash Cams Enter the 24-Hour Monitoring Era

Modern dash cams are no longer simple driving recorders. They now support
24/7 parking surveillance, impact-triggered recording, multi-channel cameras,
WiFi/Bluetooth connectivity, cloud backup, and even remote alerts.

Once the vehicle is turned off, traditional power sources such as cigarette
lighters or hardwired connections lose power or risk draining the car battery.
This makes dedicated dash cam battery packs essential.

2. Why Many Dash Cam Battery Packs Fail

2.1 Runtime Is Far Shorter Than Advertised

Many users experience a huge gap between advertised and real-world runtime,
especially with dual or triple cameras and 4K recording.

2.2 Extreme Heat Inside Vehicles

In summer, vehicle interiors can reach 60–75°C. Inferior batteries swell,
shut down thermally, and degrade rapidly.

2.3 High Peak Current Interrupts Recording

Multi-lens recording, IR night vision, WiFi activation, and G-sensor events
create sudden current spikes. Weak batteries cause reboots or corrupted files.

2.4 Frequent Cycling Shortens Lifespan

Daily charge–discharge cycles combined with heat and high current demand
quickly destroy low-quality cells.

5. Use Cases

• 24-hour parking surveillance
• 4K dash cams
• Multi-channel (front/rear/side) recording systems
• Ride-hailing fleets and taxis
• Delivery and rental vehicles
• Wireless vehicle security cameras

6. Conclusion — A Dash Cam Is Only as Reliable as Its Battery

No matter how advanced a dash cam is, it becomes ineffective if power fails
during parking mode.

Reliable dash cam batteries must deliver long runtime, stable output,
high-temperature endurance, strong protection, and long cycle life.
