Replacement Battery for Dell Inspiron 14 3421 15

This lithium-ion battery replaces original Dell packs across multiple Inspiron 14, 15 and 17 models including the 3421, 3521 and 3721 series. It fits part numbers such as XCMRD, MR90Y and 0MF69. The unit is brand new and ready for installation.

40 Wh Capacity with Four Cells

The pack stores 40 Wh at 14.8 V using four Grade A lithium-ion cells. That capacity supports typical office work and web browsing for several hours on a full charge. Runtime shortens under heavy loads such as video rendering or gaming.

14.8 V Output Voltage

The battery delivers a nominal 14.8 V, which must match the laptop's original specification. Verify the voltage printed on your old pack before ordering. A mismatch will prevent the system from charging or powering on correctly.
