Why Don’t Dash Cams Use High-Capacity Batteries?

Dash cams are usually connected to the car's power supply for continuous recording while driving. Although equipped with a built-in battery, once the power cord is unplugged, the device will shut off within seconds. Does this mean there’s a problem with the battery?

The Main Use of Dash Cam Batteries

Compared to conventional mobile phone batteries, which usually hold 2000 mAh or more of capacity, Mio’s dash cams come with much smaller batteries. This is because the main purpose of the dash cam battery is to maintain the system settings, save files after the car engine is turned off, and ensure the data integrity when encountering power failure after an emergency collision. If no external power source is connected, the dash cam will automatically shut down for safety*.

Pay Attention to Certification Labels
When Buying a Dash Cam!

Lithium batteries are widely used in consumer electronics products and automobiles, and a certified lithium battery should incorporate strict internal safety designs. The use of inferior lithium battery products in long-term or a high-temperature environment may cause battery swelling, leakage, explosion, or combustion hazards due to overcharge. Therefore, it is important to choose a dash cam equipped with certified lithium batteries for peace of mind.

Mio’s Dash Cams Have Passed Quality and Safety Inspections and Certifications

Mio's products are tested and certified for consumer safety. In addition to the CE certification for the whole device, the built-in battery also has a separate CE certification. This ensures the quality of Mio products is guaranteed by certifications for both the device and internal components!
