Why uncertified video recorder batteries and chargers can be dangerous

Company Mio Technology, a leading international developer and manufacturer of automotive electronics, talks about the dangers of using batteries and chargers in car DVRs that have not passed the laboratory safety tests and do not have the necessary certificates of quality standards. Every electronic device with a battery can be a source of danger: if its manufacturer has not paid enough attention to quality control of batteries and power circuit, the gadget can turn into a dangerous time bomb.


Example of a black box battery blown by heat

One of Mio Technology’s top priorities is to ensure the absolute safety of our products for our customers. Mio recorders use batteries and chargers that have undergone rigorous laboratory testing and certification procedures. We cover the weaknesses in the power supply of many DVRs, and how Mio negates any risks associated with using lithium-ion batteries.

Bloating of the battery from overheating

Not every lithium-ion battery is capable of handling high temperatures for very long. In summertime, a car parked with the windows shut turns into a real sauna, which negatively affects the condition of the equipment in it. And in some cases, the sun’s rays hitting the recorder can melt its case in a few hours and cause severe overheating of the battery. Many batteries after such spot heating inevitably swell and at best lose capacity, and at worst fail, making it impossible to use the recorder.


The Mio recorder sustained no damage after being heated to 105 degrees, while the other recorder melted

All Mio DVRs undergo compulsory testing in the test chamber at temperatures up to 105 ° C. As the results show, due to the use of heat-resistant and flame-resistant Bayer plastic and high-quality batteries the housing of Mio recorders does not deform, and the batteries remain fully functional.

Damage and short circuit

If the lithium-ion battery sheath is damaged, the oxygen flowing in can cause the battery to ignite. It was damage to the battery case due to design errors that was the cause of known problems with exploding smartphones. If the battery in your black box is not properly secured, it may eventually detach from its seat, and begin to contact other parts of the gadget. After months on the road shaking the battery casing may rupture, causing a fire and heavy smoke in the cabin right as you drive.


The battery in a Mio vehicle recorder is securely seated.

Batteries in Mio DVRs have a reinforced double-shell, in the body of the device they are firmly attached to the special seat, where the battery will not fall out, even with a strong jolt. As an extra measure of safety, the connection of the battery to the board of Mio recorders is through a removable connector, as it is safer in terms of possible short circuits than the not always well done soldering.


In other recorders, the battery is attached to the adhesive tape and easily peeled off

Deep battery discharge

Mio Technology is the first DVR manufacturer to create a certified test room to test the reliability of its products. Not only the final devices are checked, but also individual components such as optics and batteries.

Mio uses batteries that meet a number of requirements: the cells meet UL1642 and the assembled batteries meet UN38.3/CB/BSMI/GB. These acronyms stand for different compliance standards and testing methodologies for batteries.

Batteries for Mio gadgets are routinely tested for deep discharges and voltage peaks. Lithium-ion batteries may not recover from a deep discharge through a normal power connection. That means you won’t be able to get back to life after forgetting your DVR in the glove box for months. A discharged battery in Mio recorders will retain enough charge to provide full operation immediately when connected to a power source.

Certificates as proof of reliability

Getting a safety certification is not a bureaucratic procedure, but an official statement that the recorder is reliable. Pass state certification is not possible if the recorder is potentially fire-hazardous, shocking, made very poorly or does not meet the declared characteristics. The lack of special logos on a device may indicate that the manufacturer knowingly declined certification because the device may not have passed.


Video recorder chargers Mio with logo certifications

Mio doesn’t just use high quality batteries and chargers in its products – they undergo stringent tests to prove their reliability and safety. Every buyer of Mio technology can pay attention to the charger for the cigarette lighter: it will certainly have the logos of the various certification systems. In the American version there is a mark E13, indicating compliance with safety regulations of the European Economic Commission, as well as the EAC mark, which guarantees compliance with the. Regulations of the Customs Union.
