Using the PrimaryBattChargeCfg feature

This feature allows you to configure the primary battery charging option in the PowerManagement category. The selected charging

mode applies to all batteries installed in the system. Select one of the following modes:

• Auto — Battery settings are adaptively optimized based on your typical battery usage pattern.

• Standard — Charges the battery at a standard rate.

• Express — Charges the battery faster using the express charging algorithm, Dell's fast charging technology.

• PrimACUse — Charges the battery while plugged-in, preferred for the users who operate their system while plugged in to an

external power source.

• Custom — The battery charging starts and stops based on the settings specified in Primary Battery Custom Charge Start and

Primary Battery Custom Charge End.

– CustomChargeStart — Sets the percent value ranging from 50 to 95 at which the custom battery charging should start.

– CustomChargeStop — Sets the percent value ranging from 55 to 100 at which the custom battery charging should stop.

NOTE: CustomChargeStart percent must be less than CustomChargeStop percent, and the minimum difference

between the two can be no less than 5 percent.

Example: To retrieve the current mode of the PrimaryBattChargeCfg attribute.

Get-ChildItem -Path DellSmbios:\PowerManagement\PrimaryBattChargeCfg

If the status retrieved as Custom, then to know the percent when charging starts and ends, retrieve CustomChargeStart and

CustomChargeStop attributes.

Example: To set the battery charging mode as standard.

Set-Item -Path DellSmbios:\PowerManagement\PrimaryBattChargeCfg "Standard"

Example: To set the battery charge mode as custom and then to specify the start time and duration when the battery should be

charged.

Set-Item -Path DellSmbios:\PowerManagement\PrimaryBattChargeCfg "Custom"

• Sets the PrimaryBattChargeCfg attribute to charge battery based on user settings specified in CustomChargeStart and

CustomChargeStop attributes. If the value 'Custom' is chosen,
