FAQs

Q: Is it OK to leave a lithium-ion battery on the charger overnight?

A:

Leaving a lithium-ion battery on the charger overnight is generally safe if you use a charger, such as those from Timeusb, designed to stop charging once the battery is fully charged. Most modern lithium-ion chargers have this feature to prevent overcharging.

Q: Can I charge LiFePO4 to 100%?

A:

Yes, you can. However, charging a battery to less than 100% and avoiding complete discharge will always enhance cell longevity. Similarly, keeping the state of charge (SoC) between 20% and 80% will extend the lifespan of lithium batteries. For instance, Timeusb deep cycle lithium batteries 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.

Q: Can I charge a LiFePO4 battery with a trickle charger?

A:

Trickle charging is not suitable for lithium batteries. Using a trickle charger not specifically designed for LiFePO4 batteries can cause overcharging or damage because lithium batteries have different charging requirements compared to traditional lead-acid batteries.

What about a regular charger? For more information, refer to the article "Can I Charge LiFePO4 with a Normal Charger?"

Q: What charger should I use for LiFePO4 battery?

A:

To fully charge a 12V LiFePO4 battery, you need a charger with a voltage between 14V and 14.6V. Using a charger with a lower voltage will still charge the battery, but it won't reach 100% capacity.

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.
