Worried about choosing a battery? Comparison of the advantages and disadvantages of lead-acid batteries and lithium batteries.
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.nt.
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 makes electric vehicles lighter 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 overload,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 about three times 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.
In summary: Generally speaking, lead acid batteries are more cost effective than lithium batteries! Of course, you can choose to use lead-acid batteries or lithium batteries according to your actual needs.
Depending on the quality of the battery products, after-service sale and price, we recommend some good lead acid batteries. Batteries Acid battery brands: Changxin battery, Shinhwa battery, Mantingfang battery.
How to repair an electric vehicle battery that is not durable?
Motorcycle batteries can use lithium batteries.
Lithium manganese batteries have a voltage rating above 3.0 volts and are best suited as integrated circuit power supplies and are widely used in computers, calculators and watches. Lithium-ion batteries are widely used in mobile phones, computersportable nators, power tools, electric vehicles, emergency power supplies for street lights, navigation lights and household appliances. For small household appliances, it can be said to be the largest application group .
Lithium batteries are widely used in energy storage systems such as hydro, thermal, wind and solar power plants, uninterruptible power supplies for posts and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric batteries. vehicles, military equipment, aerospace and other fields.
Detailed information:
1. High energy. It has high storage energy density, reaching 460-600Wh/kg, about 6-7 times that of lead-acid batteries; she hasa long lifespan and can reach more than 6 years. The positive electrode is charged and discharged 1C (100% DOD) and has been used 10,000 times.
2. The rated voltage is high (the operating voltage of a single unit is 3.7V or 3.2V), which is approximately equal to the series voltage of three nickel-cadmium or nickel-cadmium rechargeable batteries. metal hydride. , which facilitates the formation of a battery power supply; Lithium batteries can be a new type of lithium battery voltage regulator technology that adjusts the voltage to 3.0V to adapt to the use of small electrical appliances.
3. She has high power endurance. The lithium-ion iron phosphate battery used in electric vehicles can achieve a charge and discharge capacity of 15-30°C, which facilitates high-current starting and acceleration; -the discharge rate is very low. It's the un of the most remarkable advantages of this battery. It can generally reach less than 1%/month, which is less than 1/20 of nickel-metal hydride batteries.

The lifespan of electric vehicle batteries is generally around 2 to 3 years if the battery has been used for an extended period of time. time, there will be If it is not durable, you can consider the following methods to repair it:
Reactivation of the battery: Fully charge the battery and leave it for a few hours, then discharge -at least more than half, charge it fully again, repeat this process several times, the battery can be reactivated.
Check battery connections: Check battery terminals and connectors for play or corrosion. If necessary, clean the battery terminals and connectors and reconnect them.
Replace the cBattery components: If the battery components (such as electrolyte, separator, positive and negative plates, etc.) have failed or been damaged, these components must be replaced to restore the performance of the battery. battery.
Check the charger: Check if the charger is working properly and replace or repair the charger if necessary.
