When the remaining battery power is low, charge your battery by
connecting your computer to ac power.
The battery is fully charged in about two to four hours. The actual
charging time depends on the battery capacity, the physical environment,
and whether you are using the computer.
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:
- 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.
