2-power Main Battery Pack Dell Latitude E5400 - Batterie - 57 mAh (2P-B-5093H)

For professionals who depend on their Dell Latitude or Precision workstation, the 2-POWER 2P-B-5093H battery delivers the endurance and reliability that generic replacements often lack. Built around a 6-cell lithium-ion core, it offers a genuine 4400mAh capacity at 11.1V, translating to 49Wh of usable energy — enough to power through long meetings, fieldwork, or cross-country flights without hunting for an outlet. Unlike budget cells that fade within months, this pack uses grade-A cells and robust protection circuitry to maintain consistent performance over hundreds of charge cycles.
