Product Features

In modern life, electronic devices have become an integral part of our daily work and life. However, over time, battery life can diminish, which can affect the experience of using the device.

What's the reason my new battery suddenly stopped working?

Lenovo THINKBOOK 16 G9 IRL-21US00BTFE batteries are usually shipped with a partial charge. (Note: It is not unusual for batteries to become warm to the touch during charging and discharging).
New batteries may be difficult to charge for the device; they have never been fully charged and are therefore "untrained". Sometimes the charger in the device will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from the device and reinsert it. The charging cycle should start again. This may happen several times during the first battery charge. Don't worry, this is completely normal.

How to extend the life of this THINKBOOK 16 G9 IRL-21US00BTFE battery?
  1. Avoid prolonged charging and discharging, which should be carried out when the battery is maintained at 20%-80%.
  2. Avoid leaving batteries unused for long periods of time, cycling batteries regularly helps to extend battery life.
  3. Avoid using the battery in extreme temperatures, use the battery at 0-45 degrees Celsius for optimal performance.
