Compatible Dell Latitude and Precision Models

This Dr. Battery replacement unit fits Dell Latitude 5570, Latitude E5570 and Precision 3510 laptops. It uses Li-polymer cells rated at 7.4V and 4000 mAh to restore original runtime. Integrated safety circuitry protects against over-charge, over-discharge, overheating and short-circuit.

Professionals needing reliable mobile power

Business users who depend on the listed Dell models for daily work will find a direct-fit solution with OEM-grade cells. Buyers whose laptops require a different voltage, such as 11.4V, or a different form factor should look at other options. The battery is not suitable for tablets or ultrabooks outside the compatibility list.

4000 mAh capacity for typical business workloads

The pack delivers enough capacity for a full day of office applications, email and web browsing on supported hardware. Intensive tasks such as sustained rendering or heavy compilation will drain the charge faster and may require a mains connection. Physical dimensions are 8.0 by 1.5 by 0.8 and the unit weighs 0.4.

Questions about this item

Which original Dell part numbers should match the 4F5YV battery for it to fit my Latitude 5570?

The replacement battery replaces Dell part numbers 21CP5, 2H2G4, 451-BBKH, HFRC3 and TXJ69; confirm your original battery carries one of these codes before installing.

Will the 7.4 V, 4000 mAh Li-polymer pack charge correctly with the existing Dell AC adapter on a Precision 3510?

Yes — the battery voltage matches the original 7.4 V specification, so the laptop's standard charger will charge it normally without any hardware changes.

How can I verify the integrated safety protection is active after the first few charge cycles?

The battery should charge smoothly to full capacity and discharge steadily without unexpected shutdowns, indicating the over-charge, over-discharge, overheat and short-circuit safeguards are working.
