## Prolonging the Battery Lifespan

Enable the battery care function to prolong the battery lifespan. With this function, you can reduce battery degradation by limiting the charging capacity or adjusting the charging time.

1. Start VAIO Control Center and select Power and Battery. (See Starting Apps to start VAIO Control Center.)
2. Select Details in Battery Care Function.

#### Hint

- Depending on your operating conditions, you can select the following settings to prolong the battery lifespan effectively.

  - 80%/50% Charging

    If you tend to use your VAIO computer while connecting it to an AC power source, it is recommended that you select 80%/50% Charging to limit the charging capacity to 80% or 50% of the total.

  - Overnight Charging

    If you tend to use your VAIO computer outdoors, it is recommended that you select Overnight Charging and set a time period for battery charging to the period in which you do not intend to use the computer, such as nighttime, to limit the charging capacity.

    With Overnight Charging, the battery pack charges to 100% when the time period is close to the end.
