Users needing longer runtime or different laptops

Questions about this item

Does this 451-BCGO-TM battery fit my Dell Precision 7540 without any extra parts?

Yes, the 451-BCGO-TM is a direct replacement for the Dell Precision 7540 and installs using the laptop's existing battery bay and connector.

Will the 7.6 V output of this 4-cell battery work correctly in a Dell Precision 7730 that originally used a 6-cell pack?

The 451-BCGO-TM is listed as compatible with the Precision 7730, so its 7.6 V output matches the system's power requirements despite the different cell count.

How can I confirm the 64 WHr capacity is recognised after installing the 451-BCGO-TM in my Precision 7530?

Check the battery information in Windows Settings or BIOS; it should report a design capacity of 64 WHr and a voltage of 7.6 V for the new pack.
