Rechargeable battery pack

Your computer includes a built-in, rechargeable battery pack that makes mobile computing a reality. When
the computer is plugged into an electrical outlet, the battery charges. If you use the computer when you
don't have access to an electrical outlet, the battery discharges to supply electricity that the computer
system requires for operation.
You can charge the battery any time you want. The battery packs of Lenovo computers support multiple
charging modes that are suitable for different power usage habits. You can switch the battery's active
charging mode in Lenovo Vantage or Lenovo BaiYing.
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.
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.
Normal mode
Normal mode is the most basic charging mode. In normal mode, it typically takes 2 to 4 hours for the battery
to charge from 0% to 100%.
Rapid charge mode
If you want the battery to be charged faster than in normal mode, switch the battery charging to rapid charge
mode. The following table lists the estimated time needed for batteries in rapid charge mode to be charged
to 80% and 100% respectively.
Table 6. Estimated charge time for batteries in rapid charge mode
Mode Time needed to charge from 0% to 80%
Rapid charge Less than 1 hour
Note: The estimated charge time assumes that the battery is charged when the PC is in sleep, hibernation,
or powered-off state.
Conservation mode
If your computer is constantly plugged into an electrical outlet, consider switching the battery charging to
conservation mode. In conservation mode, the battery will not be fully charged. Instead, the battery's charge
will be kept within 75%–80%. This is beneficial to the long-term health of the battery.
Note: If you want the battery to be fully charged before bringing the computer to work, disable conservation
mode by switching the battery charging to normal or rapid charge mode.
