solar warning stud for freeway white in uk

The life of the solar channel battery should not only be long enough, but also be able to work normally in a wide temperature range. The material inside the battery is a chemical substance. If the temperature is too high or too low, it will not work properly. Therefore, its working temperature range must meet the requirements of the actual use environment. The requirements of the relevant standards of the Ministry of Transport for this indicator are that the solar road studs must work normally within the range of -10¡ãC to 50¡ãC. In fact, the ambient temperature of solar road studs often exceeds this range, which requires more reliable and higher performance batteries to make solar road studs.
