When it comes to LiFePO4 batteries, there is often a question of whether they should be kept fully charged. In this article, we will explore the benefits and drawbacks of keeping LiFePO4 batteries fully charged and provide you with important knowledge about their proper charging methods. Redway Power, a trusted provider of OEM Lithium LiFePO4 batteries, offers high-quality solutions for various applications. Let’s dive into the details and understand the best practices for charging LiFePO4 batteries.

The Benefits of Keeping LiFePO4 Batteries Fully Charged

Keeping LiFePO4 batteries fully charged offers several advantages:

  1. Maximized Energy Capacity: Fully charged LiFePO4 batteries provide their maximum energy capacity, ensuring optimal performance.
  2. Improved Lifespan: LiFePO4 batteries tend to have a longer lifespan when they are regularly fully charged, as it helps prevent certain degradation mechanisms.
  3. Readiness for Immediate Use: Fully charged batteries are ready to be used immediately without the need for additional charging time.

The Drawbacks of Keeping LiFePO4 Batteries Fully Charged

However, there are also some drawbacks to consider:

  1. Increased Stress: Keeping LiFePO4 batteries at a high state of charge for extended periods can increase the stress on the battery, potentially leading to accelerated aging.
  2. Self-Discharge: LiFePO4 batteries have a low self-discharge rate, but keeping them fully charged can still result in a gradual loss of charge over time.

How to Keep LiFePO4 Batteries Properly Charged

To ensure the optimal performance and lifespan of LiFePO4 batteries, it is recommended to follow these charging guidelines:

  1. Use a Compatible Charger: Use a charger specifically designed for LiFePO4 batteries to avoid overcharging or undercharging.
  2. Charge to Recommended Voltage: Charge the LiFePO4 battery to the recommended voltage specified by the manufacturer.
  3. Avoid Overcharging: Do not leave the battery connected to the charger once it reaches its full charge to prevent overcharging.

Is It OK to Leave a LiFePO4 Battery on the Charger?

Leaving a LiFePO4 battery on the charger after it reaches full charge can potentially lead to overcharging, which can be detrimental to the battery’s lifespan. It is recommended to disconnect the battery from the charger once it is fully charged to avoid any unnecessary stress on the battery.

How Do You Prolong the Life of a LiFePO4 Battery?

To prolong the life of a LiFePO4 battery, consider the following tips:

  1. Avoid Deep Discharges: Minimize deep discharges and keep the battery within the recommended depth of discharge limits.
  2. Control Operating Temperatures: LiFePO4 batteries perform best within a specific temperature range, so avoid exposing them to extreme temperatures.
  3. Proper Storage: If not in use, store LiFePO4 batteries in a cool, dry place with a partial charge to maintain their health.

Q: Can overcharging LiFePO4 batteries cause damage?
A: Yes, overcharging LiFePO4 batteries can lead to accelerated aging and potential damage to the battery.
Q: How long do LiFePO4 batteries typically last?
A: LiFePO4 batteries have a longer lifespan compared to other battery chemistries and can last for 10 to 20 years, depending on various factors.
Q: What is the self-discharge rate of LiFePO4 batteries?
A: LiFePO4 batteries have a low self-discharge rate, typically around 2-3% per month.


In conclusion, keeping LiFePO4 batteries fully charged offers benefits such as maximizing energy capacity, improving lifespan, and readiness for immediate use. However, it is important to consider the drawbacks, including increased stress and self-discharge. To properly charge LiFePO4 batteries, use a compatible charger, charge to the recommended voltage, and avoid overcharging. Disconnect the battery from the charger once it is fully charged to prevent overcharging. By following these guidelines and considering tips for prolonging battery life, you can ensure optimal performance and longevity.
