How Long Does a 105Ah LiFePO4 Battery Last? Introducing the EVE LF105
One of the most common questions about batteries is, “How long will it last?” The answer, however, depends on several factors. This article post will explore the lifespan of a 105Ah LiFePO4 battery in terms of both runtime and cycle life, and introduce EVE’s 105Ah LiFePO4 battery, the LF105.
How Long Will a LiFePO4 Battery Last?
The lifespan of a 105Ah LiFePO4 battery depends on how it’s used and is best understood by considering two aspects: runtime and cycle life.
- Runtime: This refers to how long the battery can power a device on a single charge. It’s directly related to the discharge rate (the current drawn by the device). A 105Ah battery can theoretically deliver 105 amps for one hour, 52.5 amps for two hours, or 10.5 amps for ten hours. The formula is:
Runtime (hours) = Capacity (Ah) / Discharge Current (A)
However, real-world runtime can be affected by factors like temperature and battery age. Higher discharge rates typically lead to slightly shorter runtimes than the theoretical calculation.
- Cycle Life: This refers to how many times the battery can be fully charged and discharged before its capacity significantly degrades (typically to around 80% of its original capacity). LiFePO4 batteries are known for their long cycle life, often ranging from 2,000 to 6,000 cycles, and sometimes even more. A higher cycle life means the battery will last longer before needing replacement.
Several Factors Influence Cycle Life
Depth of Discharge (DOD): Shallower discharges generally extend cycle life. Discharging to only 80% instead of 100% can significantly increase the number of cycles.
Temperature: Extreme temperatures, both high and low, can negatively impact cycle life.
Charging and Discharging Rates: Adhering to the manufacturer’s recommended rates is crucial for maximizing cycle life.
Therefore, while a 105Ah LiFePO4 battery can potentially provide 105 amps for an hour, the actual runtime will depend on the load. Its overall lifespan, in terms of years, depends on how frequently it’s cycled and how it’s treated. With proper care, a LiFePO4 battery can last for many years, even decades, in certain applications..
Introducing the EVE LF105
The EVE LF105 is a 105Ah LiFePO4 battery designed for various applications requiring reliable and long-lasting energy storage. Its key features include:
* Nominal Capacity: 105Ah:Offers ample energy storage for a variety of uses.
* Nominal Voltage: 3.2V: Standard voltage for LiFePO4 cells, suitable for building battery packs.
* Long Cycle Life: 4000 Cycles (25℃): Ensures long-term performance and reduces replacement frequency.
* LiFePO4 Chemistry:Provides inherent safety and stability.
Conclusion:
The lifespan of a LiFePO4 battery depends on how it’s used. While a 100Ah battery can theoretically provide 100 amps for an hour, the actual runtime will vary based on the discharge rate. LiFePO4 batteries, like the EVE LF105, offer a long cycle life, typically thousands of cycles, making them a durable and reliable energy storage solution. By understanding the factors that influence battery lifespan and choosing a high-quality battery like the LF105, you can ensure reliable power for your applications for years to come.
