The Damage of Solar Cat Eye Road Stud Markers

There are various reasons for the damage of solar cat eye road studs, and the main damage modes are introduced below.
First, battery dead. The first possibility of a failed battery is that the solar panel is damaged. Solar panel charging did not come in, while the LED light is still working. When the battery runs out, the LED will not light up any more. The second possibility is that the charging and discharging device is damaged. The charging and discharging device of solar cat eye road stud has the function of boosting and depressurizing. When working, sensitive components will be impacted by static electricity, which may cause damage for a long time, so that the components can not reach their original functions.
 
Second, physical damage. Solar cat eye road stud are load limited. If the load limit is exceeded for a long time, the solar cat eye road stud will be damaged physically. The solar cat eye road stud will not be damaged by small vehicles and occasionally by large vehicles. However, if they are repeatedly rolled, the solar panel chips may be damaged, resulting in LED lights not being on.
Third, water leakage. There are many kinds of shell materials for solar cat eye road stud. The first is to inlay the lens of solar cat eye road stud to the surface, which requires workers to operate carefully. The solar lens glue needs to be completely filled, otherwise it will seep. But even if there is no problem with the production, after years of exposure to harsh environment, the glue may fail and separate the shell from the internal structure. The second is to clip the reflector into the solar cat eye road stud, and then pour it with special glue. Such road stud marker, even if used for many years, will not seep water.
 
Fourth, it is not resistant to low temperature. solar cat eye road stud use Ni MH batteries. The disadvantage of Ni MH battery is that it is not resistant to low temperature. When the temperature is below - 40 degrees Celsius, the battery will fail instantly. But if you use lithium batteries, it won't happen.
