Direct replacement for Xiaomi Pro X15

This 11.55V 6927mAh lithium-ion battery replaces part numbers 8FCTC, R15B05W and 31CP5/73/70-2. It is built with Grade A cells and integrated circuit protection for stable output and safety. The unit arrives brand new at 100% condition from the manufacturer.

Fits the original battery bay without modification

No adapters or extra cables are required; the pack slots into the existing compartment and connects to the stock connector. It frees the laptop from reliance on mains power and restores full mobility for work or travel. The black finish matches the OEM appearance.

80Wh capacity supports extended unplugged sessions

Typical office workloads and media playback run for hours before a recharge is needed. Heavy multi-tasking or high screen brightness will draw the reserve down faster. Users needing multiple full work days away from a socket should plan for an additional power source.
