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.
