Anker portable chargers can last up to 300-500 complete charge cycles. Keep in mind that these are only estimates and can vary according to the frequency of use and other factors.
The optimized operating temperature is at 0°F to 77°F (0℃ to 25℃). If you're storing the batteries for 1 month, a good rule of thumb is to keep them at 14°F to 113°F (-10°C to 45°C) and at 14°F to 95°F (-10°C to 35°C) if you're storing them for 3 months.
It is recommended to recharge the portable chargers at least once every 3 months.
After reaching 500 complete charge cycles (some lithium batteries may reach 300 cycles, which may be shortened by irregular use), their lifespan will come to an end. When this happens, the performance and safety of the lithium batteries will be reduced.
We suggest that you replace the battery if the following issue occurs:
1. Swelling of the battery case.
2. Liquid or obvious odor appears on the USB interface.
3. Abnormal heat occurs during use.
4. When shaking the battery, there is a sound from internal electronic components.
5. Cracked case.
6. Liquid has entered through the USB port.
1. Find a recycling facility near you.
2. Check out Earth911 or Call2Recycle to find convenient recycling options.
3. Follow your local laws and regulations for proper battery disposal.
4. Leave it at your household recycling center or place in Recycling Kiosks at Best Buy stores.
