User's Guide

The battery is fully charged in about four to eight hours. If the power adapter shipped with your computer
supports the rapid charge function, the battery is 80% charged in about one hour when the computer is
turned off.
The actual charging time depends on the battery size, the physical environment, and whether you
are using the computer.
Battery charging is also affected by the battery temperature. The recommended battery temperature range
for charging the battery is between 10°C (50°F) and 35°C (95°F).
To maximize the life of the battery, observe below tips:
• Recharge the battery completely before using it. Once the battery is fully charged, it must discharge to
94% or lower before it will be allowed to recharge again.
• Use the battery until the charge is depleted. 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.
