When many people buy rechargeable batteries, they start to hesitate between lithium batteries and lead-acid batteries, not knowing whether to buy lead-acid batteries or lithium batteries. In terms of battery price, lead-acid batteries with the same capacity are priced lower than lithium-ion batteries, with the price of lithium-ion batteries being approximately 1.5 times that of lead-acid batteries, except for special functional requirements of lithium-ion batteries. So, is the price of lithium batteries really more expensive than lead-acid batteries? Let’s briefly discuss this issue below.

Firstly, from the perspective of battery technology, the production and popularization of lead-acid batteries occurred several decades earlier than that of lithium batteries. That is to say, the production process of lead-acid batteries is more mature, and naturally the production cost is much lower than that of lithium batteries. The maturity of the production process is much higher than that of lithium batteries. So the corresponding price of lithium batteries will be much higher than lead-acid batteries. But don’t overlook the advantages of lithium batteries: they have a high capacity density, 6-7 times that of lead-acid batteries, and can discharge at high rates up to 15-30C, which lead-acid batteries cannot achieve. They are lightweight and small in size: the weight of lithium batteries is about 1/6-1/5 of lead-acid products in the same volume.

Secondly, the maximum number of cycles for a typical lithium battery is greater than 1000, while for a typical lead-acid battery, the charging and discharging cycles are approximately 300. That is to say, the number of cycles of lithium batteries is more than three times that of lead-acid batteries. In other words, it is also possible that the lithium battery needs to be replaced after the device uses a charging pool and replaces the lead-acid three times. So one lithium battery is equivalent to three lead-acid batteries. When calculating the cost of use, it can be seen that the price of lithium batteries is much cheaper than that of lead-acid batteries.

Another aspect is the lifespan of the battery. Due to factors such as environmental conditions, energy storage, charging and discharging times, and charging and discharging methods, the usage time of rechargeable batteries is limited. The service life of a typical lithium battery is between 10 and 20 years; The service life of lead-acid batteries is generally between 3-5 years; The service life of lithium batteries is 3-4 times that of lead-acid batteries. That is to say, one lithium battery is equivalent to 3-4 lead-acid batteries. From a cost perspective, lithium batteries are much cheaper than lead-acid batteries.

So, is the price of lithium batteries really more expensive than lead-acid batteries? Actually not, everyone only sees the unit price of a single product without considering the cost of using the product. It’s like when we rent a house, you have to spend 100 yuan to rent 100 meters 2 Old buildings and houses for one year; Still willing to spend 150 yuan to rent 100m 2 What about the new building suite for 3 years? This is a very simple question. So the price of lithium batteries is not more expensive than lead-acid batteries!
