The outside environment has great influence on the solar road studs.

The working temperature for normal batteries is between 0 to 50 degrees centigrade and the cycle index can reach 500. In summer, the land surface temperature of some countries can be around 60 degrees centigrade, and it is quite normal that the lowest temperature in Northeast China would minus 30 degrees centigrade in winter. However, both high and low temperature is harmful to the working condition of batteries, which will reduce the using time of batteries, and make influence on the using time of solar road stud. So the battery with good heat-and-cold resistance should be chosen to prolong the using life of solar road stud.
