How Long Does The Lifespan Of Electric Vehicle Batteries Generally Last
Electric vehicle batteries are the "heart" of electric vehicles. Once there is a problem with the battery, electric vehicles cannot function properly. Therefore, whether it is purchasing, using, or maintaining, we must be careful. When choosing electric vehicle batteries, in addition to paying attention to the price, it is also important to understand the types of electric vehicle batteries and whether lithium batteries or lead-acid batteries are better. When using it, we need to master the correct charging method in order to extend the lifespan of electric vehicle batteries. If you encounter a situation where the electric vehicle battery cannot be charged, it is necessary to repair it in a timely manner and replace what needs to be replaced. How often does the battery of an electric scooter need to be replaced? How to repair an electric vehicle battery that is not durable?
There are several types of electric scooter batteries
Lead-acid battery
The electrodes of lead-acid batteries (VRLA) are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. The advantages of lead-acid batteries for electric vehicles are low price, large capacity, and low maintenance costs. However, their large size and lack of timely disposal after disposal can lead to environmental pollution.
lithium battery
Lithium batteries are batteries that use non-aqueous electrolyte solutions. Lithium ions are removed during discharge and inserted during charging. Electric vehicle lithium batteries have high energy storage density, can withstand higher power, and also have the advantages of light weight, environmental protection, and long service life. However, the safety of lithium batteries is relatively poor, and some low-quality electric vehicle lithium batteries have the risk of explosion.
Colloidal battery
Colloidal lead-acid batteries are an improvement on lead-acid batteries with liquid electrolytes. They have a longer service life, high adaptability to environmental temperatures, and can withstand long-term deep discharge.
Nickel hydrogen battery
Nickel hydrogen battery is an alkaline battery with the advantages of high stability, good low-temperature performance, and high recycling value. However, the energy density of nickel hydrogen batteries for electric vehicles is low, and the number of cycles is not as good as that of lithium batteries.

How to look at the model of electric vehicle batteries
The battery model of an electric vehicle is printed on its front. Some products will directly indicate its battery voltage, battery capacity, and other information in Chinese, while others will provide a string of characters that consumers need to understand before they can understand. Taking "6-EVMJ-60" as an example, it represents an electric vehicle battery that contains six small batteries, each with a voltage of 2V. Therefore, the battery voltage of this model is 12V; 60 refers to a battery capacity of 60Ah. When buying electric vehicle batteries, it is important to choose the correct model, otherwise it may cause damage to the electric vehicle.

How to repair electric vehicle batteries that are not durable
Distilled water or acidic water in batteries plays a crucial role, directly affecting the charging performance of batteries. Many battery problems are caused by water shortage. Therefore, if we can replenish water to the battery every six months, it can greatly extend its lifespan.
How to repair the inability to charge the battery of an electric scooter
Connect all parts of the circuit firmly, and replace the charger if it is abnormal. Pure water should be added for pulse repair if the battery cell is dry. Detailed>>
How to repair vulcanization of electric scooter batteries
You can first discharge the battery, pour out the original electrolyte, and then inject a thinner electrolyte with a density below 1.10g/cm3. That is, add water to dilute the electrolyte in the battery to improve the solubility of lead sulfate.
Softening and repair of electric vehicle battery plates
After discharging the battery to 10.5V, use a light bulb to discharge deeply for 1-5 hours. Then use an activator to activate and repair.
How to repair water loss in electric vehicle batteries
Use a dropper to suck in distilled water and inject it into the battery through the exhaust port. Cover the exhaust hole with a breathable cover on the water filled battery to prevent dust from falling into the exhaust hole. The safety editor of Maigo reminds everyone to pay attention that when adding water to electric vehicle batteries, the principle of "less water than more" should be followed, because adding too much water at once can lead to a decrease in acid density and insufficient battery capacity.
Is it useful to add repair fluid to electric vehicle batteries
Electric vehicle battery repair fluid has a certain effect on repairing batteries, but not all batteries can be repaired with it. Generally, battery repair fluid is mainly suitable for repairing water batteries. Such batteries usually lose more water, and adding battery repair fluid appropriately can restore the battery's capacity and play a repair role; But there are also sealed maintenance free batteries, and if these batteries are damaged or run low, using battery repair fluid will not be effective.
Production of electric vehicle batteries
The production methods for different types of electric vehicles vary. Taking electric vehicle lithium batteries as an example, let me briefly explain the production and manufacturing methods of lithium batteries: mixing of raw materials → coating of positive and negative electrode plates → cold pressing of positive and negative electrode plates → cutting and dividing → stacking of positive and negative electrode plates → shell insertion → spot welding → vacuum drying → liquid injection → formation → division → forming
