Replacement battery for Xiaomi 14" Mi Pro X 14

This 15.4 V lithium-ion pack replaces part numbers R14B05W and 41CP6/63/62 in compatible Xiaomi 14-inch Mi Pro X 14 laptops. Grade A cells and built-in circuit protection are designed to reduce leakage risk and provide stable output. The unit ships brand new from the manufacturer. Installation requires opening the laptop back case to verify the original battery model number.

Practical limits of the lithium-ion interface

The 56 Wh capacity sets the total energy available between charges. Voltage is fixed at 15.4 V, so the pack delivers 3637 mAh at that nominal level. Runtime scales with the laptop's power draw; heavier workloads will deplete the charge faster. The internal protection circuit guards against over-charge, over-discharge and short-circuit conditions.

Capacity and headroom for daily use

At 56 Wh the battery supports typical office tasks, web browsing and media playback for several hours on a full charge. Demanding workloads such as sustained video rendering or gaming will exhaust the available energy more quickly. The 3637 mAh rating indicates the charge reserve at the rated voltage. Users needing longer unplugged time should consider carrying a spare pack or a compatible power adapter.

Questions about this item

Should I choose this battery by its 56 Wh rating or the 3637 mAh figure?

Both numbers describe the same cell; 56 Wh at 15.4 V equals 3637 mAh, so either specification confirms you are getting the correct capacity.

What does the 15.4 V rating mean once the battery is installed in my Xiaomi 14" Mi Pro X 14?

It matches the original voltage requirement, so the laptop's power management will recognise the pack and report charge levels normally.

Does the connector follow a standard laptop-battery interface that could limit compatibility?

The pack uses the proprietary connector defined by part numbers R14B05W, 41CP6/63/62 and 1007664-733719-1, which fits only the listed Xiaomi 14" Mi Pro X 14 series.
