Whether it is lead acid battery or lithium battery, they have their own advantages and disadvantages, so there is no way to say which is better, I can only say which one suits you best. After all, everyone's use is different, it is recommended that you refer to the advantages and disadvantages of lead-acid and lithium batteries, combined with your actual use, to choose an electric vehicle battery that is more suitable for you. Here are their respective advantages and disadvantages:
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 highlyt 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.
Disadvantages of lead-acid batteries: high weight, limited battery capacity and short lifespan. Lead-acid batteries typically have a lifespan of about three years after 400 deep charges and discharges.
Advantages of lithium-ion batteries:
1: Lightweight and small size. The volume of lithium-ion battery is 2/3 of the volume of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid battery. Lithium-ion batteries of the same volume have a higher capacity than lead-acid batteries. The reduced weight rend lighter electric vehicles and their range is increased by around 10%.
2: Long life. The average lifespan of lithium-ion batteries is about 4 years, about a year longer than lead-acid batteries. It can be charged and discharged more than 500 times. The battery has no memory and is very shock resistant.
3: Resistant to overcharge, good resistance to charge and discharge. At normal temperatures, lithium-ion batteries can be continuously charged for 48 hours without causing expansion, leakage, rupture or other accidents, and the capacity remains above 95%. And with a special charger, it can be charged and discharged quickly.
Disadvantages of lithium-ion batteries:
The production cost of lithium-ion batteries is high, the production equipment is expensive, and the labor costs represent approximately 40% of the production cost. The price is approximately threeis times higher than that of lead acid batteries. At three times the price, it's not great value for money, and it looks rather flashy. Additionally, lithium-ion batteries are not recyclable. Once worn out, they can only be thrown away or buried after thousands of times. years, future generations will not be able to use them. If you dig it up, it will be an antique.
Based on the quality, after-sales service and price of electric vehicle batteries, we recommend several good lead-acid battery brands: Changxin Battery, Shinhwa Battery and Mantingfang Battery.
The China Industrial Association of Power Sources (CIAPS) is a national organization composed of resources from enterprises (public institutions) in the battery industry. is a professional and non-profit social organization, whose competent department is the Ministry of Industry andof Information Technologies. The association was created in December 1989 and currently has more than 500 members. It includes the branch of alkaline batteries and new chemical energy sources, the branch of acid batteries, the branch of lithium batteries, the photovoltaic solar branch, the working committee on dry batteries, the branch of accessories and the Mobile Power Supply Branch, the Energy Storage Application Branch, the Battery Equipment Branch and nine other branches.
