Electric vehicles generally replace batteries every two years. The specific frequency of battery replacement depends on the battery life. Typically, electric vehicle manufacturers provide battery life standards.
Manufacturers of commonly sold electric vehicle batteries promise a 24 or 30 month warranty for lithium batteries. During this period, if the electric vehicle battery does not pose a safety risk, it does not. must be replaced. When electric vehicles are used daily, if you want the battery to last longer, you should pay attention to the maintenance of the battery vehicle. First of all, be sure to avoid sudden braking. Frequent hard braking will consume a lot of electricity and damage the battery, so it is best to avoid hard brakingthat. For daily EV charging, 30% is the minimum required, and 50% is just right.
Battery life
If you find that the battery is less than 50%, it is best to charge it immediately. Don't wait for it to be used again. , as this will cause excessive discharge, thereby damaging the battery and shortening its lifespan. When charging the battery, you should pay attention to the charging time. Don't charge it for a day or two. This will not increase capacity and will only bring the battery closer to scrap.
When using the battery, the capacity gradually fades and the performance gradually decreases until the end of the life and cannot meet the user's requirements, the battery must be replaced. In addition to knowing how often electric vehicle batteries should be replaced, everyone shouldAlso pay close attention to the working condition of the battery and replace the battery timely to ensure operational reliability.
How long does an electric tricycle battery last?
The electric vehicle battery should be replaced in approximately 4 years, on the basis of normal use. drums. Since the current batteries of electric vehicles are lead-acid batteries and lithium batteries, the maximum number of charging and discharging times of lead-acid batteries is generally around 360, which means that under driving conditions Normally, if an electric vehicle is charged once every three days, the battery of the electric vehicle will be about 3 years.
The maximum number of charges and discharges of lithium batteries is more than 500 times. If charged once every three days, the electric vehicle battery can bebe used for approximately four and a half years. So from this point of view, whether it is a lithium battery or a lead acid battery, under normal driving conditions, it only needs to be replaced with a new battery every 3 to 5 years.

Maintenance methods
1. Do not store the battery in case of power loss
The power loss condition refers to the battery. If the battery is not charged in time after use, lead sulfate crystals may occur on the plates, blocking the ion channels, resulting in insufficient charging and reduced battery capacity. The longer the battery is left unused, the more serious the damage to the battery will be. When the battery is not in use, it should be charged once a month to keep the battery in a "healthy" state.
2. Regular checks
When usingsation, if the mileage of an electric vehicle suddenly decreases by more than ten kilometers in a short time, it is likely that at least one of the batteries in the battery pack is damaged. A battery has short circuit phenomena such as broken cells, softening of the plates, and loss of active material on the plates. At this point, you should promptly go to a professional battery repair agency for inspection. , repair or assembly.
3. Do not discharge large currents
When starting an electric vehicle, transporting people or going up a hill, please use the pedals to help you and try to avoid instantaneous discharge of large currents. High current discharge can easily cause lead sulfate to crystallize, thereby damaging the physical properties of battery plates.
Different types of batteriesElectric vehicles have different lifespans. The common electric vehicle batteries on the market are currently mainly lead-acid batteries and lithium batteries, and their service life is also different.
In terms of lifespan alone, lithium batteries have a longer lifespan than lead-acid batteries. Lead-acid batteries are generally deeply charged and discharged 400 times, and their lifespan is generally about three years. The average life of lithium batteries is about 4 years, about one year longer than that of lead-acid batteries, and can be charged and discharged more than 500 times.
But they each have their own advantages and disadvantages, so the choice of electric vehicle batteries mainly depends on your own use, so you can choose a battery that suits you better. The following are lead. Baacidic substances. I hope this can give you some reference on the respective advantages and disadvantages of lithium batteries.
Lead-acid batteries: good safety performance, cheap price, high recyclability value, but heavy, limited battery capacity, short lifespan;
Lithium batteries: light , small size, long service life, overload resistance and good charge and discharge resistance, but the production cost is high and basically cannot be recycled, so the replacement price is high.
Be sure to pay attention to the quality and brand of the battery when purchasing a new battery car or replacing the battery. The battery is the heart of a battery car. If the battery is good, the performance of the battery car will be good in all aspects. If you don't know how to choose a battery, a worry-free solution is to chooseiir a brand.
Choose high-quality new batteries from high-quality brands, which can not only avoid all kinds of hidden pits that you don't want to encounter, but also have high-quality batteries, ensuring a long lifetime. use it worry-free and comfortably.
Based on the battery product quality, after-sales service and price, we recommend a very good lead acid battery brand: Changxin Battery.
As an old lead-acid battery production group, Changxin Battery has enjoyed excellent reputation and quality and has been praised by the market for many years. As a high-end product among lead-acid batteries, Changxin graphene series adopts more scientific direct-connected row structure, improved formula with higher energy density and higher technology content, bringinglonger lifespan and longer, more stable battery capacities. performance.
