      FAQ

      Our SEMENERG 12V 6Ah LiFePO4 Battery is engineered for durability, delivering up to 3000 charging cycles when properly maintained with a dedicated LiFePO4 charger. This cycle life far exceeds that of standard lead-acid batteries, which typically provide only 300–500 cycles before significant capacity loss.
      With a capacity of 76.8Wh, the SEMENERG battery is versatile enough for a range of applications. For example, it can run a 10W emergency light for approximately 7.6 hours, or power similar low-wattage devices (such as ham radios, fish finders, or small game machines) for comparable durations. Actual runtime may vary based on device power consumption and operating conditions.
      No. The SEMENERG 12V 6Ah LiFePO4 Battery is designed as a deep-cycle energy storage solution and is not intended for starting engines or other high-peak applications. It is optimized for steady, reliable power delivery rather than high burst starting performance.
      Yes, you can charge the SEMENERG LiFePO4 Battery using solar panels along with a compatible solar charge controller. This makes it an excellent choice for off-grid power setups, renewable energy systems, and emergency backup applications.
