Replacement battery for Dell Latitude E5450
This 4-cell lithium-ion pack replaces the original G5M10 unit in Dell Latitude E5450 and E5550 laptops. It delivers 7.4V and 51Whr capacity for mobile professionals who need reliable power away from a desk. The black housing matches the OEM aesthetic and installs without tools. Buyers with other Dell models or non-Latitude systems cannot use this battery.
Thermals and power behaviour
The lithium-polymer chemistry maintains stable current output and low self-discharge during daily use. Built-in circuit protection guards against overcharge, over-discharge and short circuits. CE, FCC and RoHS certifications confirm compliance with electrical safety and environmental standards. No active cooling is required and the pack operates silently.
Build integration
The battery fits the primary bay of the Latitude E5450 and E5550, freeing the AC adapter for stationary work. It replaces OEM part numbers including 0WYJC2, 8V5GX, PF69Y, 451-BBLK, VMKXM and 451-BBLN. Systems needing a higher-watt-hour pack or a different voltage must choose another model.

Questions about this item
How do I install the 4-cell 7.4 V battery in my Latitude E5450, and what step do people often miss?
Power off the laptop, unplug the AC adapter, slide the release latch, swap the pack, then press the new battery until the latch clicks — many forget to fully seat the connector before closing the latch.
What maintenance will the 6891 mAh Li-Poly pack need later?
No scheduled maintenance is required; store the system around 50 % charge if unused for weeks and keep vents clear so the pack stays cool.
What limit appears first during sustained use of the 51 Whr battery?
Runtime drops as the cells age; after several hundred full cycles the pack delivers noticeably less than the original 51 Whr capacity.
