　　Why choose button cell battery cr2025 more than lead-acid batteries?

　　Lithium batteries are small in size and light in weight, and the equipment saves cost: Nowadays, solar lights around the world are widely used as integrated road lamps. If lead-acid batteries are used, they must be buried underground around the street lamps and placed in underground boxes. However, if lithium batteries are used , because of its relatively light weight, it can be externally connected to the back of the solar panel to save costs.

　　Lithium batteries are less polluting than lead-acid batteries, and are low-carbon and environmentally friendly: As we all know, lead-acid batteries have a shorter service life. Although they are cost-effective, they are likely to have to be replaced once a year, which will greatly increase air pollution. In addition, lead-acid batteries themselves are more polluting than lithium batteries. If they are not replaced in time, they will continue to have a negative impact on the environment. Lithium batteries have zero pollution, while lead-acid batteries contain lead heavy metals that exceed standards.

　　Lithium batteries are more intelligent: Today's lithium batteries are becoming more intelligent and their functions are more complete. At present, lithium batteries can be adjusted according to users' requirements for batteries, usage time, etc. Many lithium batteries can be installed with the BMS intelligent management system, which can instantly check the battery status on the mobile phone and automatically identify the current intensity of the rechargeable battery. If there is an abnormality, the BMS system software can automatically adjust it.

　　Longer lithium battery life: Lead-acid batteries have a higher annual wear and tear, and they often take one or two years to be replaced. Moreover, the service life of lithium batteries is 3-5 years, and generally speaking, it can guarantee a three-year warranty period. The service life of the lead-acid battery circulation system is about 300 times. Compared with lithium iron phosphate rechargeable batteries, the 3C cycle system has a service life of more than 800 times.

　　Lithium battery packs have a higher safety factor and no memory: lead-acid batteries are prone to water leakage, while lithium batteries are not prone to water leakage. Lead-acid batteries have memory capacity. When the battery is not fully charged and discharged, it will cause memory loss, which will affect the service life of the rechargeable battery. And lithium batteries have no memory and can be charged at any time. It is safer and more reassuring to use. Lithium iron phosphate batteries have passed strict safety tests and will not occur even if a serious impact occurs.

　　High-efficiency energy density lithium batteries have high energy storage density, which can currently reach 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. In that case, the energy storage technology of solar lights will be better.

　　Lithium-ion battery solar lights are very heat-resistant: solar lights are exposed to the sun outdoors every day, so they have higher requirements for the temperature environment. The heat peak of lithium iron phosphate battery can reach 350~500℃, and it can be used in the environment of -20℃~60℃.

　　Market price, warranty period: The most popular rechargeable batteries on the market are 48 volts. If replaced, lead-acid batteries cost about 450 yuan, and the warranty period is one year; lithium batteries are relatively expensive, costing around 1,000 yuan, but The warranty period is 2 years.
