Replacement Battery for Inspiron 14 15 17

The Damaite XCMRD is a 4-cell lithium-ion pack rated at 14.8 V and 40 Wh. It matches a long list of Dell part numbers including MR90Y and XCMRD itself. The unit fits Inspiron 14, 15 and 17 models from the 3421, 3521, 3721, 5421 and 3537 families as well as Latitude 14 3000 and 15 3000 series.

Steady Discharge on Lithium-Ion Cells

Four cells share the load so voltage holds steady during long sessions rather than sagging after a short burst. The 40 Wh capacity is delivered through the native 14.8 V rail without an onboard converter adding loss. Heat spreads across the pack instead of concentrating on a single cell.

Hard Limits of the 14.8 V 40 Wh Pack

Capacity is fixed at 40 Wh; runtime cannot exceed what that energy budget allows. The 14.8 V output only works with laptops designed for that exact voltage. Physical dimensions follow the original XCMRD form factor so the battery will not fit chassis built for thinner or thicker packs.

Questions about this item

How much heat does the 14.8 V 40 Wh XCMRD battery produce during all-day use?

The 4-cell lithium-ion pack runs at 14.8 volts and 40 watt-hours, so its thermal output stays low enough for normal laptop operation without extra cooling.

Which Dell Inspiron model must I already own for the XCMRD battery to fit?

It fits Dell Inspiron 14-3421, 15-3521, 17-3721, 14-5421, 15-3537 and the Latitude 14 3000 and 15 3000 series listed in the compatibility table.

Will the XCMRD battery charge correctly with the original Dell AC adapter I still use?

Yes, the 14.8 V lithium-ion cells match the voltage expected by the factory charger, so the original adapter charges the pack normally.
