58Wh replacement for Dell Latitude E5440 and E5540

This new PISKEKAT battery delivers 58Wh at 11.1V using Grade-A cells. It is built as a direct replacement for the original Dell batteries in Latitude E5440 and E5540 models. The pack is certified to CE, FCC, RoHS and UL standards for safety and reliability.

Practical limits of a 58Wh lithium-ion pack

The battery is rated for more than 500 recharge cycles before capacity drops noticeably. Runtime per charge depends on the workload, screen brightness and power settings of the host laptop. Fast-charge circuitry is supported, but the actual charge speed is governed by the laptop's own charging controller.

Check your Dell part number before ordering

Confirm that the original battery carries one of the listed part numbers such as VV0NF, N5YH9, 0K8HC, 1N9C0, CXF66, WGCW6, 0M7T5F, F49WX, NVWGM or 7W6K0. Verify the laptop model is exactly Latitude E5440 or E5540; other Dell models are not supported. Ensure the battery compartment is free of damage that could prevent a secure fit.

Questions about this item

Should I choose the 58Wh version for my Latitude E5540 or E5440?

Yes — this 58Wh, 11.1V pack is built as a direct replacement for both the Latitude E5540 and E5440, matching the original capacity and voltage.

What does the 58Wh rating actually give me in daily use?

The 58 watt-hour capacity restores the same runtime the laptop shipped with, and the Grade-A cells are rated for over 500 recharge cycles.

Which connector standard does this battery use and what does it limit?

It uses the proprietary Dell Latitude battery interface, so it only fits E5540 and E5440 chassis that accept part numbers such as N5YH9, VV0NF or 0K8HC.
