Battery Maintenance and Safety Guidelines

The internal Lithium-Ion rechargeable battery require routine maintenance and care in their use and handling. Read and follow the guidelines below to achieve the maximum battery life span and safely handle the battery.

1) Avoid extreme ambient temperatures

For a higher battery life span, the device should be operated in an ambient temperature range between 16° to 25° C (62° to 77° F). It’s especially important to avoid exposing your device to ambient temperatures higher than 35° C (95° F), which can permanently damage battery capacity. That is, your battery won’t power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further. Also, never charge your device unattended or in any place where there is a risk of fire.

Even storing a battery in a hot environment can damage it irreversibly. When using your device in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. Once the battery’s temperature returns to its normal operating range, its performance will return to normal as well.

2) Store the device half charged when you store it long term

If you want to store your device long term, two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage. Therefore, we recommend the following:

    • Do not fully charge or fully discharge your device’s battery — charge it to around 50%. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge -a deep discharged battery must not be recharged for safety reasons, so it should be replaced and disposed properly. Conversely, if you store it fully charged for an extended period, the battery may lose some capacity, leading to shorter battery life.

    • Be sure to turn off the device to avoid additional battery use. To turn off the device completely, use the power switch and not the automatic power off function. The device uses some battery power during the automatic power-off state, so the battery can be completely discharged if the device is left in this state for a prolonged period.

    • Place your device in a cool, moisture-free environment that’s less than 32° C (90° F).

    • If you plan to store your device for longer than six months, charge it to 50% every six months.

3) Replace the battery when necessary

The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again. Use a two to three-year life expectancy for batteries that do not run through complete charge cycles.

Consider replacing the battery with a new one if you note that the battery run time drops below about 80% of the original run time. Also, deep discharged batteries must be replaced for safety reasons.

4) Properly dispose the battery

Lithium-Ion batteries are subject to disposal and recycling regulations that vary by country and region. Always check and follow your applicable regulations before disposing of any battery. Many countries prohibit the disposal of waste electronic equipment in standard waste receptacles.

Place only discharged batteries in a battery collection container. If the connector is removed or the cable cut, use electrical tape or other approved covering over the battery connection points to prevent short circuits.

5) Properly handle the battery

Please note the below safety precautions when handling the device internal battery:

    • Do not disassemble, crush, or puncture a battery.

    • Do not short the external contacts on a battery.

    • Do not dispose of a battery in fire or water.

    • Do not expose a battery to temperatures above 60 °C (140 °F).

    • Keep the battery away from children.

    • Avoid exposing the battery to excessive shock or vibration.

    • Do not use a damaged battery.

    • If a battery pack has leaking fluids, do not touch any fluids. Dispose of a leaking battery pack (see the disposal and recycling considerations above).

    • In case of eye contact with fluid, do not rub eyes. Immediately flush eyes thoroughly with water for at least 15 minutes, lifting upper and lower lids, until no evidence of the fluid remains. Seek medical attention.
