How long is the life of lithium iron phosphate battery and lead-acid battery

How long is the life of the lithium iron phosphate battery? In an environment where the quality of the lithium iron phosphate battery is relatively good, the attenuation can be controlled within 5%, and within 15% in the second year. Although the details are also related to utilization load and utilization frequency, here is just a possible expression. Based on various factors, the utilization characteristics of iron iron phosphate lithium-ion batteries can be expressed as: relatively large size, poor low-temperature performance, and can maintain a relatively flat decay rate during the lifespan. Generally, it can be used for 8 years; But if you use it in the south. The life of lithium iron phosphate battery is longer than 8 years. The lithium iron phosphate battery has a cycle life of more than 2000 times, and the standard charge (5 hour rate) can reach 2000 times. Lead-acid batteries of the same quality are new for half a year, old for half a year, and for maintenance and maintenance for half a year, at most 1 to 1.5 years, and lithium iron phosphate batteries used under the same conditions, the theoretical life will reach 7 to 8 years. Comprehensive consideration, the performance value is more than 4 times theoretically that of lead-acid batteries. High-power exile can charge and discharge high-current 2C quickly. With a dedicated charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C, but lead-acid batteries have no such function. The life span of lithium iron phosphate batteries is 4-5 times longer than that of lead-acid batteries. As far as lead-acid batteries have a relatively high level of skill, there is no problem with their life reaching 5 years. The lithium-ion battery has the problem of collapsed layout due to the negative material graphite, even if it is discarded for five years without using it, it will be scrapped. How long is the service life of a lead-acid battery? From the perspective of utilization and conditioning, whether you are a maintenance-free battery or an ordinary lead-acid battery, the normal service life is about 2-3 years. If you save it, it is 3 to 4 year. The domestic single-cell 12V lead-acid battery is designed to have a floating charge life of 5-8 years, but it has been completely scrapped in 1-2 years; no matter any lead-acid battery (including domestic and imported), it cannot escape the vicious circle of early scrapping in use. Maintenance-free battery, as the name suggests, the biggest feature is maintenance-free. Do not add distilled water to the base during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. Although relatively, its price will be more expensive than ordinary batteries. As for the service life, the replacement cycle of maintenance-free lead-acid batteries under normal conditions is about 3 years. In the process of charging and discharging lead-acid batteries, lead sulfate crystals gradually appear on the electrode plates. This phenomenon leads to the aging of the battery, which is expressed as: the battery is hard to charge and discharge; the battery capacity is low; it further promotes the corrosion of the electrode plate and reduces the battery life.
