Replacement battery for Alienware 14 and M14X R3 R4

This KingSener 0G05YJ lithium-ion battery is a new replacement part for Dell Alienware 14, A14, M14X R3 and M14X R4 series laptops. It matches the original 69WH capacity and 11.1V voltage. The black pack replaces Dell part numbers G05YJ, Y3PN0, 8X70T and P39G. It suits owners restoring runtime on these specific models.

Capacity and voltage match

The single specification that decides fit is the 69WH capacity at 11.1V, which must match the original battery label exactly. A different watt-hour rating or voltage will prevent the laptop from charging or reporting capacity correctly. Verify the original battery shows 69WH and 11.1V before ordering.

Straightforward swap with connector care

Installation requires removing the bottom case screws, disconnecting the old pack and connecting the new one to the same motherboard header. The most common issue is a loose or misaligned connector that causes the system to not recognise the battery. Ensure the plug seats fully and the retention clips click before reassembling the chassis.

Questions about this item

How long will the 69WH capacity run my Alienware 14 under typical mixed use?

The 69 watt-hour rating means the pack stores that much energy; actual runtime depends on your screen brightness, CPU load and peripherals, so expect several hours of office work and less under heavy gaming.

What does the 11.1V voltage mean for compatibility with my M14X R3 or R4?

The 11.1V output matches the original Dell specification for the Alienware 14, M14X R3 and R4 series, so the laptop's power management will recognise it without any voltage mismatch.

Will this battery physically fit the Alienware 14D-1528 chassis and screw holes?

It is built to the same form factor as the original 0G05YJ, Y3PN0 and 8X70T packs, so it aligns with the battery bay and mounting points on all listed Alienware 14 and M14X models.
