Which one has a longer lifespan, lithium iron phosphate battery or lead-acid battery?

Lithium iron phosphate batteries have a cycle life of over 2000 times and can be charged at a standard rate of 5 hours, up to 2000 times. A lead-acid battery of the same quality can last for six months, including new and old ones, and maintenance and upkeep, with a maximum of 1-1.5 years. However, when used under the same conditions, lithium iron phosphate batteries have a theoretical lifespan of 7-8 years. Overall, the cost performance ratio is more than 4 times that of lead-acid batteries in theory. High current discharge can quickly charge and discharge at a high current of 2C. With a dedicated charger, charging at 1.5C can cause the battery to overflow within 40 minutes, and the starting current can reach 2C. However, lead-acid batteries do not have this performance.

Lithium iron phosphate battery packs can generally be used for about 8 years; But if used in the south. The lifespan of lithium iron phosphate batteries is even longer than 8 years. The theoretical lifespan of lithium iron phosphate battery packs also exceeds 2000 charge and discharge cycles, even if charged once a day, it can last for more than five years. Generally speaking, for daily household use, it can be recharged every three days and can also be used for about eight years. However, due to the poor low-temperature performance of lithium iron phosphate batteries, their lifespan will be relatively longer in southern regions.

The design float life of domestic single 12V lead-acid batteries is 5-8 years, but they are completely scrapped within 1-2 years; Regardless of any lead-acid battery (including domestic and imported), there is always a vicious cycle of early scrapping in use. During the charging and discharging process of lead-acid batteries, lead sulfate crystals gradually appear on the electrode plate. This phenomenon leads to battery aging, which is manifested as: difficulty in charging and discharging the battery; Reduced battery capacity; Furthermore, it further promotes the corrosion of the electrode plate and reduces the service life of the battery.

The recyclable lifespan of general lead-acid batteries can reach one and a half years, and high-quality lead-acid batteries can even be recycled for up to two years. However, in general, the lifespan of lead-acid batteries begins to decline after six months of use. Its usage power will gradually decrease.

In recent years, the usage of lead-acid batteries has been increasing, not only limited to factory use, but also increasingly relied on in people's daily lives. Although the production technology and process of lead-acid batteries have been improved in recent years, there are still troublesome problems that arise during continuous use. That is to say, the service life of lead-acid batteries seems to always be so unsatisfactory. On the one hand, the service life of lead-acid batteries does not meet the standard, and its service life is shortened very quickly.
