Can Limefuel batteries be carried on an airplane?

Limefuel batteries contain Lithium-ion cells which fall within TSA restrictions posted for Lithium-ion batteries for carry-on luggage. Limefuel batteries are safe for carry-on luggage but should not be packed in checked luggage due to FAA regulations.
Even if an item is typically permitted, it may be subject to additional screening or not allowed through if it triggers an alarm during the screening process, appears tampered with or poses other security concerns. Final decision lies with the TSA on whether to allow items on the plane. Limefuel can only confirm that our batteries follow TSA guidelines. We can not guarantee that our batteries will always be allowed to be carried on or used on a plane. We accept no responsibility for denial of battery carry-on or any other issue that may occur concerning a Limefuel battery at the airport.
Please, always check TSA and FAA regulations prior to travel.

Can my device be used while charging it with the Limefuel battery?

Yes, you can use your device while it is charging from the Limefuel battery. Be aware that this will cause your device to take longer to charge than if you were not using your device at the same time.


How many times will a Limefuel battery pack charge my device?

This varies widely depending on device and the Limefuel battery you have. To calculate, take the mAh of your Limefuel battery and divide that by the mAh of your device’s battery. If you do not know the mAh of your device’s battery, it can usually be found on the battery itself, in specifications from the manufacturer or by searching Google.
For example, if you have the Limefuel Blast L180X and an HTC One smartphone, take 18000mAh divided by 2300mAh (18000/2300=7.83). You should be able to charge the HTC One approximately 7 times with the L180X.


I’ve tested my battery and I’m not getting the full mAh from it. Is my battery defective?

All lithium batteries lose some energy and are not 100% efficient. Although a battery may be rated at 13000mAh, it will not fully discharge all of the stored battery power. Some energy is lost through heat and resistance. Some power may also be lost when the battery is not in use depending on the condition of the storage environment.
If you believe your Limefuel battery is underperforming substantially, please contact us to troubleshoot and determine the issue.


How long will it take the Limefuel battery to charge my device?

The time it takes for the Limefuel battery to charge your device varies depending on device and the battery output port you chose to connect your device to. Typically, charging your device will take about as long as it would if you were to charge with the original wall charger.


How many uses or cycles can I get out of my Limefuel battery?

The high quality lithium battery cells found in Limefuel batteries will last for over 500 cycles before they lose some of their ability to store energy. A cycle is one full charge and discharge of the battery. After the 500 cycles, the battery will still function and charge your device, possibly just not at the full mAh capacity.
If your Limefuel battery is at the end of it’s life, please recycle it responsibly.


How long can a Limefuel battery be stored without use?

Limefuel batteries should retain some charge for up to one year. However, there will be some power loss and the battery may not hold it’s entire charge. We recommend you charge and discharge your battery once a month.


Can the Limefuel battery cells be upgraded?

No. Because Limefuel batteries are completely sealed for safety, the case should not be opened and the internal components should not be modified in any way. Please do not open or tamper with the battery.
If your Limefuel battery is at the end of it’s life, please recycle it responsibly.
