Direct Dell Replacement

This new lithium-ion battery replaces Dell part numbers XRDW2, YGMTN, V8VNT, 312-1390, 8TT5W, XCMRD and N121Y. It is built for owners of compatible Dell notebooks who need a 14.8V, 41Wh, 4-cell pack to restore original runtime. The supplier notes two different batteries exist for some models, so physical comparison with the original unit is essential before installation.

Steady Discharge Profile

Lithium-ion chemistry delivers a stable voltage curve across the full 41Wh capacity, avoiding the sharp drop-off seen in aged packs. The four premium cells maintain consistent output during extended work sessions, video playback or mixed workloads without sudden shutdowns. Rigorous supplier testing targets reliable cycle life under daily charge and discharge patterns rather than short benchmark bursts.

14.8V Platform Constraint

The pack operates strictly at 14.8 volts, so it only fits Dell systems designed for that nominal voltage. Builders needing a different voltage, higher watt-hour rating or alternative cell count cannot use this unit. CE and RoHS certifications confirm compliance with safety and environmental standards for the specified voltage class.

Questions about this item

Does the 41Wh 4-cell lithium-ion battery run hot or make noise during all-day use?

Lithium-ion cells generate minimal heat and operate silently, so the 41Wh pack stays cool and quiet through a full workday.

What must my Dell laptop already have for this 14.8V battery to work?

Your laptop must accept a 14.8V 41Wh 4-cell pack and match one of the listed part numbers such as XRDW2, YGMTN, V8VNT, 312-1390, 8TT5W, XCMRD or N121Y.

Will this battery fit the same bay as the original Dell 312-1390 unit I am replacing?

Yes, it is built to the same 4-cell 14.8V form factor, so it slots into the existing bay without modification.
