The difference between lead-acid batteries and lithium batteries is mainly reflected in the following aspects:

Environmental protection: Lithium batteries have no pollution, while lead-acid batteries have pollution from heavy metal lead.

Safety: The safety of power lithium batteries (lithium manganese oxide, lithium iron phosphate) differs depending on the materials. Lead-acid battery technology is quite mature and is safer than lithium batteries.

Specific energy: The mass ratio and volume ratio of lithium batteries are about 40% higher than that of lead-acid batteries.

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

Service life: The current commonly used lithium iron phosphate has no memory effect after being charged 1,500 times. It has about 85% storage capacity after 1,500 times, while the lead-acid battery is about 500 times, and the memory effect is obvious.

Self-discharge rate: The monthly self-discharge of lithium batteries is <3%, and that of lead-acid batteries is 15~30%. The difference is obvious.

Discharge characteristics: For batteries with the same capacity, lithium batteries can discharge about 30% more electricity than lead-acid batteries under high current discharge.

Voltage platform: The voltage platform of lithium batteries is >3V, and that of lead-acid batteries is 2V (Editor: Wu Zhao).

Recycling residual value: At present, lithium batteries have basically no residual value, and few people recycle discarded lithium batteries on the market; while the market recycling price of lead-acid batteries is relatively clear, and the residual value is close to one-quarter to one-third of the purchase price. About one.

Generally speaking, lead-acid batteries and lithium batteries are different in many aspects, mainly in terms of environmental protection, safety, price, service life, self-discharge rate, discharge characteristics, voltage platform and recovery residual value. In actual applications, the appropriate battery type can be selected according to needs.
