2-power Dell Latitude 5400 Batería principal - Batería - 46 mAh (2P-R8D7N)

The 2-POWER Dell Latitude 5400 Main Battery Pack stands apart from generic replacements by delivering a precise electrical and mechanical match for Dell's 14-inch business notebook. While many third-party cells force a compromise between runtime, fit, and safety, this pack is engineered to mirror the original 46 mAh lithium-ion architecture, ensuring the system recognises the battery correctly and charges it under Dell's own power management rules. The result is a drop-in upgrade that restores true mobility without firmware warnings or unexpected shutdowns.

In daily use

After installation, the Latitude 5400 reports the new pack as a genuine Dell battery, so Windows battery percentage, remaining time, and health estimates work normally. Users can expect consistent runtime across mixed office workloads, video conferencing, and travel. The pack's internal controller communicates with the notebook to optimise charge cycles, reducing wear when the system is frequently docked or left plugged in. Because the cell stack is matched to Dell's original specification, heat generation stays within safe limits even during fast charging.
