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 PC Manager.
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 typical time needed for batteries in rapid charge mode to be charged to
80% and 100% respectively.

Mode Time needed to charge from 0% to 80%
Rapid charge Less than 1 hour
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.
Overnight battery charging mode
Some people follow a regular pattern when using their computers. They finish their workday with the
computer at a low battery charge level. They plug in their computers at night and need the battery to be fully
charged the next morning so they can unplug the computer and bring it to work. These activities happen at
approximately the same time each day. If this sounds like you, consider enabling overnight battery charging
mode for the battery.
Overnight battery charging mode affects battery charging during the night hours, the time when you're
usually asleep. When it is enabled, the computer regularly adapts its charging behavior based on observation
of when you plug in the computer at night and unplug it in the morning. During the nighttime, the battery is
charged to a particular range and is kept within that range for an extended period, before being further
charged to 100%. Overnight battery charging mode ensures safe charging during the night and is beneficial
to the long-term health of the battery.
Note: With overnight battery charging mode enabled, if you break your routine one day by unplugging the
computer much earlier than usual in the morning, you may find that the battery is not fully charged.
If the battery pack of your computer supports overnight battery charging mode, it can be enabled in Lenovo
Vantage or Lenovo PC Manager.
