Lithium-ion battery useful tips

Lithium-ion batteries are used in most wireless devices because they are lightweight, can hold a charge, and can be recharged repeatedly. Because these batteries are more sensitive than alkaline batteries—like those used in flashlights and other household devices—they need to be treated with care.

In order to keep your lithium-ion batteries safe and improve their efficiency, we recommend the following actions:

  • Follow the battery usage, storage, and charging guidelines provided in your wireless device’s user guide. Do not open your battery pack.

  • Purchase chargers and accessories that are certified, approved, or otherwise compatible with your device. If you see an example of an unsafe mobile device or accessory, please report it immediately.

  • Avoid damaging the battery by not crushing, puncturing, or putting pressure on it.

  • Keep the device away from heat sources such as direct sunlight and cooking surfaces. Sustained hot or extremely cold weather or temperatures can also impact your battery’s performance.

  • Keep the battery away from other metal objects like coins and keys because they can impact its electrical connections.

  • Avoid exposing the battery to water, which could cause corrosion.

  • Avoid dropping your device, which could potentially damage the battery.

  • If you plan to store your device for a long period of time, keep your battery at about 50% of its charging capacity and turn the device off to prevent the battery from unnecessary use.

  • Install any updates to your operating system to keep up with the latest battery efficiency enhancements.

  • Do not overcharge batteries.

  • Stop charging your battery if you see or smell smoke, fluid, or other odors or if your battery looks misshapen, discolored, or hot to the touch.
