The battery is an important part of solar wall light 97 led. Solar wall light 97 led is a high-efficiency solid-state light source based on a semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, it injects holes in the P area and injects into the N area. After the electrons diffuse to the active area, they recombine by radiation to emit photons, which directly convert electrical energy into light energy. Solar wall light 97 led manufacturer is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, solar wall light 97 led will become the choice for energy-saving road lighting. Batteries are now divided into lead-acid batteries and lithium batteries. Solar wall light 97 led manufacturer is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, solar wall light 97 led will become the choice for energy-saving road lighting. The function of the battery is to store energy. The length of time that solar wall light 97 LEDs are lit and the number of days to maintain a rainy day largely depends on the battery. Therefore, battery maintenance is particularly important. How can we effectively extend the life of the battery? We should do the following:

　　1, prevent overcharging

The life and performance of solar wall light 97 led batteries are closely related to the heat accumulation inside the battery. The heat source inside the battery mainly comes from the power loss of the internal electrochemical reaction. The product of charging voltage and charging current can be simply seen. In the oxidation reaction, the floating charge current increases, generating more heat. During constant voltage charging, the floating charge current increases with the increase of temperature, which further increases the temperature. Thermal runaway is a special phenomenon caused by the vrla battery structure. Thermal runaway often causes serious hazards such as battery dehydration, bulging of the casing, and serious battery scrap. To prevent overcharging, the charging voltage should be provided in strict accordance with the manufacturer's instructions. It is now possible to build a combined power supply to realize intelligent management. The first thing to note is that the settings must be correct, and secondly, unauthorized personnel cannot change it at will.

　　2, prevent over-discharge

The depth of discharge is closely related to the number of charges and discharge cycles (service life) designed for the battery. For example, when the discharge depth is 5<lunk;GT;, the number of cycles is 10,000. When the discharge depth is 50<, the number of cycles is only 800. Excessive discharge will cause the battery to no longer be in state or even scrapped. Different discharge rates have different discharge time and termination voltage, and the effective capacity is also different, which is affected by the ambient temperature. No longer list and draw related curves here. The battery specifications of different manufacturers are given. The maintenance personnel shall pay attention to and strictly follow the relevant data settings of the monitoring unit, and shall not change it at will. Now rack power manufacturers are designed to have battery-powered functions, that is, when the solar wall light 97 led battery is discharged to a set end voltage, the battery discharge circuit is automatically cut off by monitoring instructions. More manufacturers consider that the monitoring unit cannot detect the battery termination voltage or cannot send commands for some reason (depending on its working power supply). Therefore, maintenance personnel should also pay attention to the reliability of these hardware circuits during inspection, inspection and maintenance.

　　 3. Prevent insufficient charging

Insufficient charging is mainly caused by too low charging voltage or too low charging. Or a problem with the rack system.

　　4, control the ambient temperature

When the temperature of the battery increases, the electrolyte activity increases, the internal resistance of the battery decreases, and the floating charge current increases, which leads to intensified corrosion of conductive elements and shortened life. On the contrary, the electrolyte activity decreases, the internal resistance of the battery increases, and the battery discharges to the load. Ability is weakened. Therefore, it is very necessary to monitor and maintain the temperature and ambient temperature of the solar wall light 97 led.
