Damaite 42Wh 11.4V 4-cell laptop battery for Latitude E5280 E5480

42Wh 4-cell replacement battery

This 11.4 V lithium-ion pack replaces the original Dell Latitude E5280 and E5480 battery with a 42 Wh, four-cell design. It matches part numbers 3DDDG and 03VC9Y for direct fitment. Buyers restoring mobility to a compatible Latitude will find the correct voltage and capacity here.

Not for machines outside the E5280 and E5480 series

The unit supersedes the factory-installed cell when runtime has degraded or the pack no longer holds charge. Swapping is worthwhile when the original battery reports reduced capacity or fails to power the system unplugged. Laptops requiring a different voltage, cell count or form factor cannot use this pack.

Steady output through a work session

The four-cell lithium-ion chemistry delivers consistent 11.4 V power during extended use rather than only in short bursts. Capacity of 42 Wh supports typical office workloads across a full day without sudden voltage sag. Thermal behaviour remains stable under continuous discharge.
