Precision 7670-7780 replacement battery

This new lithium-ion battery replaces the Dell Precision 7670 7680 7760 7770 7780 series internal pack. It supplies 11.55V and 83Wh of capacity in a black housing. The part matches OEM numbers RCVVT X26RT NWDC0 and is ready for immediate installation.

Voltage and capacity match

The single specification that confirms fit is the 11.55V 83Wh rating paired with the listed Precision model numbers. If your service tag shows a different voltage or watt-hour value this unit will not be compatible. No other electrical or mechanical data is provided by the supplier.

Sustained discharge behaviour

Lithium-ion chemistry delivers steady voltage through most of the discharge curve rather than a sharp drop-off. The 83Wh rating reflects total energy available under a continuous load, not a peak burst figure. Actual runtime varies with system power draw and thermal conditions.

Questions about this item

How long will the 83 Wh capacity keep a Precision 7670 running on battery?

The 83 Wh rating matches the original Dell specification for the Precision 7670, 7680, 7760, 7770 and 7780 series, so you can expect the same runtime as a factory-new Dell battery.

What connector and voltage does this 11.55 V pack use to communicate with the laptop?

It uses the Dell proprietary battery connector and 11.55 V output that the Precision 7670, 7680, 7760, 7770 and 7780 motherboards expect, enabling full charge reporting and firmware handshake.

Will the black RCVVT pack fit inside the chassis of a Precision 7770 without modification?

Yes, the pack is built to the exact form factor of Dell part numbers X26RT and NWDC0, so it slides into the Precision 7770 battery bay and secures with the original screws.
