Genuine Dell 43Wh replacement battery

This 11.4V lithium-ion pack is built to Dell specifications for Latitude 7480, 7490, 7380, 7390, 7280 and 7290 notebooks. It restores original runtime for mobile professionals who rely on these ultraportable chassis. The three-cell design matches the factory voltage and capacity without modification.

OEM three-cell construction and connector

The battery uses a direct-fit connector that aligns with the internal socket on every supported Latitude model. No adapter cables or firmware tricks are required; the pack seats flush against the magnesium deck and the latch engages with the same click as the original unit. Genuine Dell cells and protection circuitry maintain the thermal and charge-profile safeguards engineered for these systems.

Limits of the 43Wh three-cell format

A 43Wh rating caps real-world runtime to a single work session on typical productivity loads, so users who need all-day autonomy away from power will still require a charger or a higher-capacity alternative. The 11.4V nominal voltage is fixed by the three-cell topology and cannot be increased without changing the laptop's power subsystem. Compatibility is restricted to the six Latitude models listed; other Dell families use different keying and voltage rails.
