FAQ
What charger should I use for LiFePO4 battery?
To fully charge a 12V LiFePO4 battery, you need a charger with a voltage range of 14.4V±0.2V. Using a charger with a lower voltage will still charge the battery, but it won't allow it to reach 100% capacity.
Can I charge a LiFePO4 battery with a trickle charger?
Trickle charging is unsuitable for lithium batteries. Charging a LiFePO4 battery with a trickle charger not designed for this battery type can result in overcharging or damage, as lithium batteries have different charging requirements compared to traditional lead-acid batteries.
Should I charge LiFePO4 to 100%?
Charging a battery to less than 100% and avoiding complete discharge consistently enhances cell longevity. Likewise, operating lithium batteries within a 20%-80% state of charge (SoC) significantly extends their lifespan. For instance, Power Queen deep cycle lithium batteries can endure over 4,000 deep cycles at 100% Depth of Discharge (DoD), exceed 6,000 cycles at 80% DoD, and surpass 15,000 cycles at 60% DoD.
Is it OK to leave a lithium-ion battery on the charger overnight?
Leaving a lithium-ion battery on the charger overnight is generally safe if you're using a charger like Power Queen's, which automatically stops charging once the battery reaches full capacity. Most modern lithium-ion chargers have this feature to prevent overcharging.
How to choose the right charger for my LiFePO4 lithium 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 recommended. It's also important to use a charger specifically designed for the battery's chemistry. Furthermore, if you're using a standard lead-acid charger for a LiFePO4 battery, ensure it lacks features like desulfation or dead battery mode, as these can harm the LiFePO4 battery.
