The Professional Series design targets business users who need reliable power for daily mobile work. Integrated circuitry protects against over-charge, over-discharge, overheating and short-circuit.

Check original part number

Confirm that your current battery carries part number 4F5YV or WJ5R2 and shows 7.4V on its label. The supplier title also references an 11.4V variant, so matching the exact voltage is essential for compatibility. Verify the physical dimensions of 8.0 by 1.5 by 0.8 and weight of 0.4 against the bay in your chassis. Ensure the laptop model is listed in the compatibility list above.

Suits professionals replacing a worn Dell Latitude

Ideal for owners of the listed Latitude 5570, E5570 or Precision 3510 machines who want a new Li-polymer battery with OEM-grade cells and built-in safety features. Not for users whose laptop requires a different voltage or part number, or who need a higher capacity than 4000 mAh. Buyers with other Dell series should look for a battery matched to their specific model.
