Lithium-ion Batteries: How to Choose a More Cost-Effective Lead-Acid Battery

The battery is the core component of an electric car. It has been taken over by lithium-ion batteries compared to batteries for electric cars. Currently, batteries for electric cars are mainly lead-acid and lithium batteries. Why don't lithium batteries completely replace lead-acid batteries like electric cars? One very important reason is that lead-acid batteries would be safer in the eyes of car owners. So why is lead acid safer than lithium batteries? How to choose between lead-acid and lithium batteries to get a good deal?lithium ion battery VS lead acid battery Small experts today to talk about, I hope to be able to provide some reference for you to choose a car to choose the battery.

Why is lead-acid batteries safer?

When it comes to the battery fire safety of electric vehicles, it is the problem of spontaneous combustion and explosion. This rarely happens in lead-acid batteries, which is mainly related to the characteristics of the battery. Lead-acid batteries are composed of lead and lead oxide, and the main component of the electrolyte is sulfuric acid. These components are very stable and will not react violently on contact.

Of course, it is not to say that lead-acid batteries do not have a little is a safety risk hidden problems are not. Lead-acid battery business internal information once a student short circuit occurs, will electrolyze the water in the electrolyte into hydrogen and oxygen. Once too much accumulation inside the battery system, will also spontaneously combust when encountering an open flame.

Therefore, although lead-acid batteries do not explode, they have the potential for spontaneous combustion.lithium battery vs lead acid Therefore, when using lead-acid batteries, it is important to avoid high temperatures, in case of short-circuiting of the battery, keep away from firing, and in case of serious bulging and deformation, replace the battery in time.

How to choose between lead-acid and lithium batteries to get a good deal?

As you can see above, lead-acid batteries are safer than lithium-ion batteries. They are safe because they are made of different materials and structures. Due to these differences, there are also differences in price, lifespan, range and experience. So, as a car owner, faced with the choice between lead-acid and lithium-ion batteries, what should you do to make them cost-effective? Let's analyze them one by one.

Price:The price difference between lead-acid and lithium-ion batteries is about 2 to 3 times. At this point, it's time to look at the budget for purchasing a car. If the budget is under 2000 dollars, the cost of 20AH lead-acid battery is about 500 dollars, while the cost of lithium battery is about 1200 dollars. Obviously, the lead-acid battery should be chosen. If you choose lithium batteries, the whole car is either inferior or inferior, safety and durability are not guaranteed.

Life expectancy: lead-acid battery development cycle charging and discharging times is about 300~500 times, while lithium battery is about 1000~1200 times. In general business, lead-acid battery technology can be used through the use of 3 years, while lithium batteries can be effectively used for 5 years. If we want our students to use it longer, we can choose lithium batteries ourselves; if they want to be more affordable, they can choose lead-acid batteries according.

Range: Even at the same capacity, both have different range performance. Due to the different density of the batteries, lithium-ion batteries can store electricity better than lead-acid batteries, so they can travel longer distances. Taking 48v20AH as an example, lead-acid batteries have a range of about 60 kilometers, while lithium-ion batteries have a range of about 70-80 kilometers. For longer distances, lithium-ion batteries are more cost-effective.

Car experience:Lithium-ion batteries have advantages in terms of range and portability. Imagine carrying a 15kg Li-ion battery and a 40kg lead-acid battery. Whether it's changing batteries or riding with a heavy load, lithium batteries are more convenient.

Through the above one by one introduction, I believe we have a certain understanding of how to choose lead-acid batteries and lithium-ion batteries. Small experts suggest that if it is a family car, try to choose lead-acid batteries. It is not only cheap and affordable, but also very safe. Although the range and service life may be shorter, these are acceptable for a family car. As for lithium-ion batteries, it is more suitable for some high-end models with high power and ultra-high capacity. In these models, lithium-ion batteries are more adaptable.
