FAQs
Q: Is it ok to leave a LiFePO4 lithium battery on the charger?
A:
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?
A:
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?
A:
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?
A:
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%?
A:
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.
