Q: Is it ok to leave a LiFePO4 lithium battery on the charger?
If the correct voltage limit is set for the LiFePO4 lithium-ion battery, it is safe to leave the battery on the charger overnight. Timeusb Battery utilizes a LiFePO4 cell with a nominal voltage of 12.8V and a fully charged voltage of 14.6V. A charger with a 14.4-14.6V CC/CV output is suitable, provided it does not exceed roughly 1C maximum current output. As long as the CC/CV profile is followed, the maximum voltage is correct, and the current is not excessive, your battery will charge safely and fully.
Q: What voltage should LiFePO4 lithium batteries be charged at?
The appropriate charger depends on the voltage of your LiFePO4 lithium batteries. For 12V LiFePO4 batteries, the recommended charger is the Timeusb 14.6V charger.
Q: 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. 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?
Trickle charging is not suitable for lithium batteries. Using a trickle charger that isn't specifically designed for LiFePO4 batteries can lead to overcharging or damage, since lithium batteries have different charging requirements compared to traditional lead-acid batteries.
What about a regular charger? For more details, refer to the article "Can I Charge Lifepo4 with a Normal Charger?"
Q: Should I charge LiFePO4 to 100%?
Charging a battery to less than 100% and avoiding complete discharge consistently enhances cell longevity. Similarly, keeping the state of charge (SoC) between 20% and 80% will extend the lifespan of lithium batteries.
Timeusb deep cycle lithium batteries, for instance, can endure over 4000 deep cycles at 100% Depth of Discharge (DOD), over 6000 cycles at 80% DOD, and more than 15,000 cycles at 60% DOD.
