How to Properly Maintain Lithium Batteries

With the rapid promotion of new energy technologies and continuous advancements in electric vehicle (EV) battery systems, high-performance lithium batteries have become a household staple. As the power source for EVs, lithium batteries are favored for their lightweight design, durability, and high cycle life. However, unlike lead-acid batteries, lithium batteries require different usage and maintenance practices. To ensure optimal performance and longevity, here are some important tips for maintaining lithium batteries:

1. Timely Charging

• Initial Charging: When lithium batteries are shipped, they typically have a partial charge (around 50%). Before the first ride, it’s advisable to fully charge the battery. This helps offset self-discharge effects and activates the battery's active materials.
• Avoid Deep Discharge: Do not completely drain the battery during use. Over-discharge can significantly damage lithium batteries, reducing their lifespan by up to three times. Stop riding as soon as the low battery warning appears and recharge promptly.

2. Efficient Charging Practices

• No Memory Effect: Lithium batteries can be charged at any time, even if they
• Avoid Overcharging: Once the charging indicator light signals completion, unplug the charger promptly to prevent overcharging, which could degrade battery performance.

3. Addressing Self-Discharge

• Periodic Charging: If the battery is unused for an extended period, charge it every 60–90 days to maintain optimal health. The best storage state for lithium batteries is around 40%–60% charge.
• Ideal Storage Voltage: The recommended storage voltage for lithium batteries is between 3.8V and 3.9V, representing about half of their full capacity.

4. Proper Storage Temperature

• Recommended Conditions: Lithium polymer batteries can operate in a wide temperature range (-20°C to 45°C), but room temperature is optimal for minimizing ag
• Adaptation to Climate: For regions with extreme temperatures, specialized batteries are needed. In northern regions, low-temper

5. Follow Manufacturer Instructions

• Storage and Protection: When not in use, store the battery in a cool, dry, and

By following these guidelines, you can maximize the performance and lifespan of your lithium battery, ensuring safe and efficient usage for your electric vehicle
