Which is better, lead-acid battery or lithium battery?

It is necessary to comprehensively consider factors such as actual needs and budget. The reason is: if you pay more attention to safety and environmental protection, you can choose lead-acid batteries; if you pay more attention to energy density and service life, you can choose lithium batteries.

Lead-acid batteries and lithium batteries each have their own advantages and disadvantages. Which one is better depends on the actual needs and usage scenarios.

1. Safety: Lead-acid batteries do not contain organic electrolytes, and accidents such as fire and explosion generally do not occur. Lithium batteries have a certain sealed space and contain organic matter. If used incorrectly, accidents such as fire and explosion may occur. Therefore, in terms of safety, lead-acid batteries are better than lithium batteries.

2. Energy density: One kilogram of lithium battery contains 3-4 times the energy of one kilogram of lead-acid battery. In other words, under the same weight, lithium batteries can run farther than lead-acid batteries. Therefore, in terms of energy density, lithium batteries are better than lead-acid batteries.

3. Lifespan: A set of good-quality lithium batteries can be cycled about 1,000 times, while lead-acid batteries are only about one-third of lithium batteries. Therefore, in terms of service life, lithium batteries are better than lead-acid batteries.

4. Environmental protection: Lithium batteries have no pollution (not absolute), while lead-acid batteries have pollution from heavy metal lead.

5. Price: The price of lithium batteries with the same capacity is more than double that of lead-acid batteries.

6. Self-discharge rate: lithium battery monthly self-discharge

7. Charging method: Lithium iron phosphate can be charged 1500 times without memory effect. After 1500 times, the storage capacity is about 85%, while the lead-acid battery is about 500 times, and the memory effect is obvious. .

8. Voltage platform: The voltage platform of lithium batteries is >3V, and the lead-acid battery is 2V.

In summary, lead-acid batteries and lithium batteries each have their own advantages, and factors such as actual needs and budget need to be considered when choosing. If you pay more attention to safety and environmental protection, you can choose lead-acid batteries; if you pay more attention to energy density and service life, you can choose lithium batteries.
