What is a Built-in Battery in a Dash Cam?

Unlike dash cams that rely solely on capacitors, which are designed for extreme temperatures and quick power delivery, a “dash cam with built in rechargeable battery” incorporates a small, typically lithium-ion or lithium-polymer battery.

This battery’s purpose isn’t to power continuous recording for hours on end while your car is off.

If that were the case, you’d constantly be asking, “how long do dash cam batteries last,” and the answer would likely be “not long enough.” Instead, its main functions are:

• Parking Surveillance: This is where the battery truly shines. When your car is parked, the dash cam can switch to a low-power mode, relying on its internal battery to power motion detection or G-sensor activation. If an impact or movement is detected, it wakes up and records a short clip, all without draining your main car battery. This is critical for security, answering the need for a “car dash camera with built in battery” that protects your vehicle while it’s unattended.
• Graceful Shutdown: In the event of a sudden power cut e.g., your car battery dies, or you disconnect the charger, the internal battery provides enough juice for the dash cam to save the last few seconds of footage before shutting down. This prevents data corruption and ensures crucial evidence isn’t lost.
• Temporary Operation: For quick setup or moving the camera between vehicles, the built-in battery allows the dash cam to be powered on and configured briefly without an external power source.

Battery vs. Capacitor: What’s the Real Difference?

This is a common discussion point in the dash cam world, and understanding it is key.

• Batteries Lithium-ion/Lithium-polymer:
  • Pros: Can hold a charge for longer, enabling effective parking mode functionality without constant external power, and allow for a quick setup.
  • Cons: More susceptible to extreme temperatures can degrade in very hot or cold climates, potentially swelling or losing capacity, generally have a shorter lifespan than capacitors, and over time, “how long do dash cam batteries last” becomes a more pressing question as their capacity diminishes.
• Capacitors:
  • Pros: Extremely durable, highly resistant to temperature fluctuations ideal for harsh climates, much longer lifespan, and won’t swell.
  • Cons: Cannot hold a charge for long periods, meaning they require constant external power for parking mode usually via a hardwire kit, and cannot power the camera independently for more than a few seconds.
