Long time.
The lifespan of most lithium batteries is designed to be approximately 1,000 times longer (ordinary ternary lithium battery materials), or 3 to 4 years. The lifespan of lead-acid batteries is about 300 times, and the maximum is 500 times.
A charge cycle means that all of the battery's energy is used from full to empty, then charged from empty to full. This is not the same as a single charge. For example, a lithium battery only consumes half its power the first day and then recharges slowly.
If it's still the same the next day, i.e. charging half the time and charging twice in total, this can only be counted as one charging cycle, and no two. multiple charge cycles to complete one cycle. Each time a charge cycle is completed, the battery capacity decreases a little.

Notes:
1. The lifespan of electric vehicle batteries is very long. Lithium iron phosphate batteries should be charged and discharged frequently and should not be used. be stored for long periods. When driving an electric vehicle, you should get into the habit of charging it after 80% of the battery is used. Regardless of the distance traveled, it is best to recharge the battery and not wait until it is exhausted to recharge it.
2. When charging the electric vehicle battery in the vehicle, the electric door lock must be closed. Do not charge the battery backwards. When charging, try to charge it fully at once.
3. When the electric vehicle battery is not used for a long time, it should be charged once a month. stStore the battery once it is fully charged. Do not store it in a power loss state.
4. When using the battery charger, use the corresponding charger. Since the battery raw materials and production processes of lithium batteries are different, the technical requirements of chargers are also different, so special chargers must be used for charging.

The difference between lead-acid batteries and batteries lithium
1. Different materials
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Battery is a type of battery. Its function is to store limited electrical energyand use it in a suitable place.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is produced with lead-acid batteries whose electrodes are mainly made of lithium. lead and its oxides. The electrolyte is a solution of sulfuric acid in a battery. Lead-acid batteries are produced with lead, which is toxic, and the waste produced during production can also cause environmental pollution. Lithium batteries do not have such problems.
2. Different voltages
Lithium battery voltage: 3.7V Lifespan: 500 times Note: The weight is 30%-40% lighter than nickel metal hydride batteries, and the capacity is higher than nickel-metal hydride batteries. The battery is above 60%. But he doesn'tnot resistant to overload. If overloaded, it will be The temperature will be too high, which will damage the structure and lead to an explosion.
Battery voltage (lead-acid): 2V Service life: 200-300 times Note: This is a general car battery (it is 6 2V connected in series to form 12V), battery life without adding water. at 10 years old, but height and weight are most important.
3. Different prices
Lithium batteries are expensive when it comes to safety; Batteries are relatively safe; their duration of use varies. Lithium batteries have a relatively long lifespan.
Lithium batteries are better than storage batteries. Although most electric vehicles now use storage batteries due to pricing concerns, lithium batteries can completely replace lead-acid batteries.

< p>Currently, batteries on the market are divided into two camps: lead-acid and lithium batteries each have their own advantages. , which gives consumers The purchase brings certain difficulties. Next, let's see the differences between these two batteries.
The difference between lead acid batteries and lithium batteries
1. Product price:
Currently available on the market The price of mainstream lead-acid batteries sold online is generally around 450 yuan, while lithium batteries are more expensive, generally around 1,000 yuan.
2. Lifespan:
The lifespan of lead-acid batteries is generally around 2 years, while lithium batteries are more durable and have a lifespanlifespan of 4 to 5 years; lead-acid batteries are generally fully charged and discharged within 300 times, while lithium batteries are fully charged and discharged more than 500 times.
3. Mass volume:
With the same capacity, lead-acid batteries are heavier and larger than lithium batteries.
4. Battery Capacity:
Compared to lead-acid batteries, lithium batteries have a higher average voltage and high energy density. Batteries of the same size, lithium batteries have a larger capacity.
5. Warranty period: The warranty period of lead-acid batteries is generally 1 year, while the warranty period of lithium batteries is longer, which can be guaranteed for 2 years .
Advantages and disadvantages of lead-acid batteries and lithium batteries
Avadvantages of lead-acid batteries:
Compared to lithium batteries, lead-acid batteries are relatively cheaper, have higher recycling prices than lithium batteries, and have better performance high rate discharge.
Disadvantages of lead-acid batteries:
Lead-acid batteries are relatively heavier and contain sulfuric acid and some heavy metal substances, which are corrosive and can easily cause environmental pollution. Additionally, lead-acid batteries have a lower energy density and their lifespan is not as good as lithium. batteries.
Advantages of lithium batteries:
Compared to lead-acid batteries, lithium batteries are smaller, lighter, more portable and have a relatively longer lifespan. In addition, lithium batteries have greater energy, can crazydeliver larger currents, adapt better to high and low temperatures, are less affected by temperature factors and are more environmentally friendly.
Disadvantages of lithium batteries:
The safety and stability of lithium batteries are relatively poor. If used incorrectly, there is a risk of explosion. In addition, lithium batteries cannot be discharged at high currents, the production requirements are high, and the cost is higher.
Which is better, lead acid battery or lithium battery?
Lead acid battery and lithium battery each have their own advantages . choose the one that suits you. Although lithium batteries have many advantages, their technology is not yet perfect enough at present, and the first products are often not yet mature. Afteryears of precipitation, lead-acid battery technology has become more mature and cheaper. It is relatively better at present and has always been very popular among users.
However, lithium batteries are the future trend of the battery industry, and the technology is gradually improving. After improving the cost-performance ratio, I believe they can replace lead-acid batteries in the future.
