TAURKENAM G5M10 7.4V 51Wh 4-cell laptop battery

Direct replacement for Latitude E5450 E5550 E5250

This 7.4 V 51 Wh lithium-ion pack is built to fit Dell Latitude E5450 E5550 E5250 models. It restores original run-time for mobile professionals who need a reliable power source without changing chargers or BIOS settings. The 4-cell layout keeps the profile slim for 15.6 inch chassis.

Four-cell polymer construction

The battery uses a 4-cell Li-polymer design weighing about 13 oz and carries CE FCC RoHS certification. Built-in short-circuit over-voltage discharge and over-current protections guard both the pack and the laptop during daily charge cycles. A screwdriver set ships in the box so the swap can be done at a desk without hunting for tools.

Upgrades worn or swollen original packs

Replaces ageing Dell 8V5GX R9XM9 WYJC2 1KY05 080-854-0066 0WYJC2 451-BBLN units that no longer hold a full charge. The jump is worth it when run-time has dropped below half of new capacity or the case shows swelling. Not for users whose laptop model sits outside the listed Latitude series or who need a higher-wattage pack than 51 Wh.
