1. Advantages of lithium batteries
1. The lifespan of lead-acid batteries is generally 2 to 3 years. When used under the same conditions, the lifespan of new lithium-ion batteries is generally 2 to 3 years. 4 to 5 years. Of course, this is just a theory and the actual lifespan varies depending on users' usage habits.
2. Lithium batteries have no memory effect. Regardless of the battery condition, it can be charged and used at any time. Most batteries need to be charged after the battery is exhausted to avoid memory effects.
3. The volume of lithium battery is about 2/3 of that of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid battery.
2. Advantages of lead acid batteries
1. The price is close to people and there are special channels for recycling old batteries. With the same capacity,The surface price of lithium batteries is about three times that of lithium batteries. Although the lifespan of lithium batteries is theoretically three times longer than that of lead-acid batteries, this seems to only offset each other. costs more in the initial investment. In fact, an important factor has not been taken into account, namely that the lithium battery is currently broken and there are practically no recycling channels. Even if it is available, it cannot be sold. a lot of money, while lead-acid batteries can recoup at least around 30% of the price of a new battery. Although lead-acid batteries typically only last about a year and a half, lithium batteries still deteriorate after two years of use. I replaced them with new lead acid batteries and they can regain their vitality. However, lead acid batteries, which are still old, remain ahe good deal in comparison, at least for ordinary people commuting to and from work.
2. The cruise range can meet daily use. With the same volume, lithium batteries can run farther, but when the mileage increases, the cost also increases, and the effect is not very obvious to ordinary people who go to or from work, or do their shopping. It is found everywhere in town. The charging socket can be charged at home overnight, which is usually sufficient. If you need it temporarily, you can also get it at work or at a friend's house. for nearby transport. If you are a little further away, you can take a car or drive a 4x4.
3. Easy to replace. There is no management system for lead-acid batteries. If they break down, simply replace them. Lithium batteries are too delicate.You need to protect the card etc. There does not appear to be a unified standard in the market. If it breaks, you usually have to return it to the manufacturer. is not just for yourself. It is convenient. If it breaks, you can find accessories anywhere. If it breaks, you must return it to the manufacturer for processing.
4. Safe and reliable. A lot of news about the explosion of electric vehicles is related to lithium batteries, and lead-acid batteries basically eliminate this possibility. This is also an important reason why lead acid batteries can last a long time.
What are lithium batteries and lead acid batteries?
Lithium battery: The average lifespan is about 4 years, about one year longer than lead-acid batteries, and can be charged and discharged more than 500 times. Of course, if the battery you buy is a relatively inferior batteryure, or if you do not pay attention to the maintenance of the battery during daily use, it will seem that it will last for a year. At most, you can only run more than 10 kilometers.
Lead-acid battery: Generally, it can be charged and discharged in 400 times, and its lifespan is about three years.
Compared with lithium batteries, the disadvantages of lead-acid batteries are obvious, that is, they are bulky, inconvenient to use, have limited battery capacity, and have a relatively short lifespan.
However, lead-acid batteries also have the irreplaceable advantage of lithium batteries, which is why lead-acid batteries remain widely used.
Advantages of lead acid batteries:
1. Good safety performance. Lead-acid batteries are easy to maintain. You can knock them over, fix them a little and continue to use them.
2. Cheap price.The price of lead-acid batteries is about 1/3 that of lithium-ion batteries, which shows how low the price is.
3. Recyclable reverse repair. Lead acid batteries are highly recyclable. Once worn out, you can go to an electric car store to exchange them for new ones. You can exchange them for a new set of batteries by paying the price difference, thus minimizing losses. a great advantage for users. Battery lead can also be recycled and reused, reducing environmental pollution.
Based on product quality, after-sales service and price, we recommend several relatively good lead-acid battery brands: Changxin Battery, Shinhwa Battery and Mantingfang Battery.
Lithium-ion batteries are lightweight and have high specific energy, but they are very safe and cost-effective.
The batterLithium-ion batteries are rechargeable batteries, while lead-acid batteries are alkaline batteries: lithium-ion batteries have a lifespan of over 2,500 times and lead-acid batteries have a lifespan of about 800 times. times. In other words, for the same weight, lithium batteries can travel further than lead acid batteries. Therefore, in terms of energy density, lithium batteries are better than lead-acid batteries.
From a lifespan perspective, a set of good quality lithium batteries can be cycled about 1,000 times, while lead acid batteries are only about one third of that of lithium batteries. Therefore, in terms of service life, lithium batteries are better than lead-acid batteries.
Lead-acid battery
1: (Hard!) The lead-acid boss has always been strong and allowed others to be strong, and the breeze blewt on the hills. He lets others do what he wants, and the bright moon shines on the river as a principle. Lead-acid batteries are easy to maintain. You can knock them over, fix them a little and continue to use them.
2: (Cheap!) The reason why the main boss was able to dominate the battery community for many years and sit as boss is entirely due to this cheap reason! Besides being cheap, it's still cheap.

Lithium battery:
1: (light, small size) Li batterythium developed since childhood
Lead-acid battery with the same capacity on the market Compared to the volume of lithium batteries, lead-acid2/3 of the volume of the battery and about 1/3 of the weight of the batteries lead. Lithium batteries of the same volume have a higher capacity than lead acid batteries. Reducing weight increases the range of electric vehicles by approximately 1
0%.
2: (Increased lifespan) Lithium batteries are well known for their health. The average lifespan of lithium batteries is about one year, about 1.5 times longer than lead-acid batteries. charged and discharged more than 500 times, and the battery will last forever. Memory, strong resistance to earthquakes.
3: (Resistance to overcharge, good resistance to charge and discharge) Lithium batteries have opened the eight extra meridians since childhood, so that at normal temperatures, the beatLithium batteries can be charged continuously for 48 hours without battery. Expansion and leakage In case of accidents such as liquid rupture, the capacity remains above 95%. And with a special charger, it can be charged and discharged quickly.
The production cost of lithium batteries is high, and the production equipment is expensive and labor costs account for
about 40% of the production cost . The price is about three times that of lithium batteries. lead-acid batteries. At three times the price, the quality/price ratio is not very high. It looks rather flashy and the lithium battery is not recyclable. Once worn out, you can only throw it away or find a place to bury it. After thousands of years, future generations will dig it up and it will be an antique.
