Direct replacement for Latitude 7340 7440 7640

This 11.4V lithium-ion pack delivers 57Wh of capacity and matches the original 3ICP6/65/78 part number. It fits Dell Latitude 7340 7440 7640 series notebooks and replaces WW8N8 and 047T0 units. The black housing aligns with the factory colour scheme.

Single-unit package simplifies swap

The box contains only the battery itself — no tools, screws or adapter cables are supplied. You reuse the existing fasteners and connector from the old pack. A 12-month warranty covers defects in materials or workmanship.

Straightforward installation with common pitfalls

Removal usually requires a Torx or Phillips driver to free the bottom cover, then the battery connector unplugs from the motherboard. The most frequent issue is forgetting to disconnect the internal cable before lifting the old cell, which can damage the socket. Ensure the replacement clicks fully into place before reassembly.

Questions about this item

How many charge cycles can the 57Wh lithium-ion cell handle before capacity drops?

The 57Wh lithium-ion pack is rated for typical cycle life; expect gradual capacity loss after several hundred full cycles.

What thermal limit throttles the 11.4V battery during continuous heavy load?

Internal protection cuts output if cell temperature exceeds safe thresholds during sustained high-current draw.

Does the 57Wh battery generate noticeable heat or fan noise when the laptop runs all day?

The battery itself runs silently; any heat or fan noise comes from the laptop chassis under load.
