6-Cell Li-ion 11.1V 5200mAh Replacement

This new PISKEKAT battery fits Dell Latitude E5400, E5410, E5500 and E5510 models. It uses grade-A cells and meets CE and RoHS standards. The black pack replaces OEM part numbers KM742, KM769, RM656 and T749D.

Steady runtime for daily workloads

The 5200mAh capacity delivers consistent power through a full workday rather than a brief burst. Cells maintain voltage under continuous drain so the system avoids sudden throttling. Certification testing confirms stable output across the discharge curve.

Upgrade from worn 6-cell packs

Swapping a depleted original restores the notebook to its factory runtime without needing a higher-capacity chassis. The jump is worth it when the old pack holds less than half its design charge. Buyers needing 9-cell endurance or a different voltage should look elsewhere.
