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.

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.

The 14.6V 10Ah LiFePO4 battery charger is specifically designed for LiFePO4 batteries. The low internal resistance of the lithium cells allows the battery to receive the full output from the charger. With a constant 10A current, it takes approximately 10 hours to fully charge a 12V 100Ah LiFePO4 battery (100Ah ÷ 10A = 10 hours).

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.

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.
