64 Wh Lithium-Ion Battery for Precision 7730 7740

This 64 Wh lithium-ion battery replaces the 5TF10 unit in Dell Precision 7730, 7740, 7530 and 7540 laptops. It uses premium four-cell construction rated at 7.6 V and carries CE and RoHS certification. The pack is sold new with a one-year replacement warranty.

Who This Suits and Who Should Look Elsewhere

It suits owners of the listed Precision models who need a direct replacement and can verify the physical match against their original battery. Buyers with other Dell laptops or a different battery shape should look elsewhere because this pack is not compatible with those systems.

Capacity and Voltage Decide Fit

The decisive specification is the 64 Wh capacity combined with the 7.6 V rating; only laptops designed for that exact energy and voltage will accept the pack. Confirm the original battery matches the product photos before ordering.

Questions about this item

Which Dell Precision models accept this 64 Wh 5TF10 battery?

It fits the Precision 7730, 7740, 7530 and 7540; compare the original battery to the photos because two different batteries exist for these models and they are not interchangeable.

Will the 7.6 V lithium-ion pack work with the existing charging circuit in my Precision 7530?

Yes, the 7.6 V lithium-ion design matches the factory voltage for those Precision models, so the original charger and power-management system handle it without changes.

How can I confirm the battery is delivering its rated 64 Wh after installation?

Run a full charge cycle, then check the reported full-charge capacity in the BIOS or Dell Power Manager — it should read close to 64 Wh when the pack is new.
