As a common in-car electronic device, the dash cam is usually designed and tested to withstand harsh environments such as extreme cold, direct sunlight, and high heat. Generally, it can operate reliably within a temperature range of -20℃ to 70℃. However, once the temperature exceeds this range, the stability and lifespan of the dash cam may be compromised.
It is important to note that some dash cams carry potential risks due to their battery design. When purchasing, consumers should always choose products from reputable manufacturers and avoid uncertified devices—especially models equipped with lithium batteries, which require extra caution.
For dash cams that need to withstand both high and low temperatures, we recommend using wide-temperature nickel-metal hydride (NiMH) batteries.
Compared to ordinary high/low-temperature NiMH batteries, wide-temperature NiMH batteries provide better adaptability and stability. Many users are particularly interested in the T-BOX series wide-temperature NiMH batteries from EPT Battery, so let’s take a closer look at their features.
