FAQ
What charger should I use for LiFePO4 battery?
To fully charge a 12V LiFePO4 battery, you need a charger that provides a voltage between 14V and 14.6V. If you use a charger with a lower voltage, it will still charge the battery, but it won't reach 100% capacity.
Can I charge a LiFePO4 battery with a trickle charger?
Trickle charging is unsuitable for lithium batteries. Using a trickle charger not designed for LiFePO4 batteries could result in overcharging or damage due to the distinct charging needs of lithium batteries, which differ significantly from those of traditional lead-acid batteries.
Can I charge LiFePO4 to 100%?
Yes, you can. However, charging a battery to less than 100% and avoiding complete discharge can extend its lifespan. Keeping a lithium battery's state of charge (SoC) within the 20%-80% range will also help prolong its life. For instance, Power Queen deep cycle lithium batteries are designed to endure over 4,000 deep cycles at 100% Depth of Discharge (DoD), over 6,000 cycles at 80% DoD, and more than 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 when using chargers such as those from Power Queen designed to automatically stop charging once the battery reaches full capacity. Modern lithium-ion chargers typically include this feature to prevent overcharging.
How to choose the right charger for my LiFePO4 lithium battery?
It's important to verify that your charger supplies the correct current and voltage for the LiFePO4 lithium battery you're charging. Using a 24V charger with a 12V LiFePO4 battery is not recommended. It's crucial to use a charger that is designed specifically for your battery's chemistry. Furthermore, if you're using a standard lead-acid charger for a LiFePO4 lithium battery, ensure it doesn't include features such as desulfation or dead battery mode, as these could potentially harm the LiFePO4 battery.
