Battery charging is also affected by its temperature. The recommended temperature range for charging the
battery is between 10°C (50°F) and 35°C (95°F).
Note:
You can check the battery temperature in Lenovo Vantage or Lenovo PC Manager.
To maximize the life of the battery, once the battery is fully charged, it must discharge to 94% or lower
before it will be allowed to recharge again.
To extend your battery's lifespan, the battery may optimize its full charge capacity based on your usage.
After prolonged periods of limited use, full battery capacity may not be available until you discharge to as
low as 20% and recharge completely. For more information, refer to the power section of Lenovo
Vantage.
