What is the difference between a lithium battery and a LiFePO4 battery?

Lithium batteries generally refer to lithium-ion batteries with various cathode materials like cobalt or manganese, offering high energy density but lower thermal stability. In contrast, LiFePO4 batteries use lithium iron phosphate as the cathode, which provides enhanced safety due to its more stable chemical structure, a longer cycle life, and better resistance to high temperatures.

What is the lifespan of a LiFePO4 battery?

The lifespan of a LiFePO4 battery is significantly longer than that of many other battery types. Typically, a LiFePO4 battery can endure 2,000 to 5,000 charge and discharge cycles, translating to a lifespan of 5 to 10 years or more, depending on usage and maintenance.

Is it OK to leave a LiFePO4 battery on the charger?

Yes, it is generally safe to leave a LiFePO4 battery on the charger, as these batteries are designed with built-in protection circuits to prevent overcharging. However, it is always best to use a charger specifically designed for LiFePO4 batteries to ensure optimal safety and performance. 

How to charge LiFePO4 battery?

To charge a LiFePO4 battery, use a compatible lithium iron phosphate charger that matches the battery's voltage and capacity. Connect the charger, ensuring correct polarity, and charge until full. Avoid overcharging by using a charger with an automatic cut-off feature to maintain battery health and longevity.
