        FAQ

        Q: What charger should I use for LiFePO4 battery?

        A:

        To fully charge a 12V LiFePO4 battery, a charger that supplies between 14V and 14.6V is required. Using a charger with a lower voltage will still charge the battery, but it won't achieve a full 100% capacity.

        Q: Can I charge a LiFePO4 battery with a trickle charger?

        A:

        Trickle charging is inappropriate for lithium batteries. Using a trickle charger that isn't designed for LiFePO4 batteries may result in overcharging or damage because lithium batteries have different charging needs compared to traditional lead-acid batteries.

        Q: Should I charge LiFePO4 to 100%?

        A:

        To maximize the lifespan of a battery, it's beneficial to avoid charging it to full capacity and prevent complete discharges. For lithium batteries, maintaining a state of charge (SoC) between 20% and 80% significantly enhances their longevity.

        Specifically, Power Queen deep cycle lithium batteries demonstrate exceptional durability: they can endure over 4,000 deep cycles at a 100% Depth of Discharge (DOD), surpass 6,000 cycles at 80% DOD, and exceed 15,000 cycles at a 60% DOD.

        Q: Is it ok to leave a LiFePO4 lithium battery on the charger?

        A:

        When charging a LiFePO4 lithium-ion battery with the correct voltage settings, it is safe to leave the battery on the charger overnight. Power Queen batteries, which use LiFePO4 cells, have a nominal voltage of 12.8V and reach 14.6V when fully charged. To charge these batteries, a charger with a constant current/constant voltage (CC/CV) output between 14.4V and 14.6V is ideal, ensuring the current output does not exceed approximately 1C. By adhering to the CC/CV charging profile, maintaining the appropriate maximum voltage, and avoiding excessive current, you can achieve a safe and complete charge for your battery.

        Q: How to choose the right charger for my LiFePO4 lithium battery?

        A:

        It's crucial to ensure your charger provides the appropriate current and voltage for the LiFePO4 lithium battery you're charging. For instance, using a 24V charger on a 12V LiFePO4 battery is not advisable. It's also essential to use a charger specifically designed for your battery's chemistry. Moreover, when using a standard lead-acid charger for a LiFePO4 lithium battery, make sure it lacks features like desulfation or dead battery mode, which could be harmful to the LiFePO4 battery.

        Q: How long does it take to charge a 12V 100Ah LiFePO4 lithium battery?

        A:

        The 14.6V 20Ah LiFePO4 battery charger is intended for charging LiFePO4 batteries. The battery can accept the full output from the charger due to the low resistance in the lithium cells. A 12V 100Ah LiFePO4 lithium battery takes around 5 hours to completely charge using a constant 20A current.
