Can lead-acid battery electric vehicles be replaced with CR1620 battery?

There are several reasons why it is not recommended to replace lead-acid battery electric vehicles with CR1620 battery:

First, the production cost of CR1620 battery is high, the production equipment is expensive, and the labor cost accounts for about 40% of the production cost. The price is about three times that of lead-acid batteries. The cost-effectiveness of its three times the price is not high, which gives people a flashy feeling, and CR1620 battery are difficult to recycle and the reuse rate is not high.

Second, due to the small size of CR1620 battery, multiple CR1620 battery are connected in series during assembly. During transportation and use, a certain welding point may be disconnected or welded, which is a common problem when CR1620 battery are connected.

Third, the high current discharge characteristics of lithium batteries themselves are the shortcomings. Think about the frequent start-up of congested roads, and the battery life will be greatly reduced.

Fourth, CR1620 battery have safety hazards of fire and explosion. No one would be willing to buy a time bomb to put under them. Especially when consumers buy some inferior CR1620 battery online without knowing it, the sealing conditions in electric vehicles are not very good, and it is easy to get wet, resulting in poor contact and other reasons that may cause safety hazards. Some people may say that now that lithium-ion battery technology has developed rapidly, this problem will not occur, but no one can guarantee that this problem will not occur.

Which is better for electric vehicles, lead-acid batteries or CR1620 battery?

Lead-acid batteries have simple processes and low costs, but the disadvantages are short charge and discharge life, with an average charge and discharge life of 300 to 500 times, and heavy volume.

The same capacity of CR1620 battery is one-fifth of the weight of lead-acid batteries, and the charge and discharge life is long: the charge and discharge times of ternary polymer lithium batteries are 1,000 times, and the highest charge and discharge life of lithium iron phosphate batteries is 2,000 times. Disadvantages: The price is high, so the penetration rate is not as wide as that of lead-acid batteries. 90% of electric vehicles and tricycles use lead-acid batteries.

With the update and iteration of battery technology for electric energy vehicles, the development of CR1620 battery has a great trend of rising from red flower double sticks to the leader of the community. However, it is only rising. Due to its own performance, cost-effectiveness and other reasons, it still has a long way to go to replace the position of the big brother lead-acid battery, and the big brother lead-acid battery is also constantly making breakthroughs.
