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.
