Replacement battery for Xiaomi Mi Ruby 15.6

The KingSener N15B01W is a 15.4V 2600mAh 40.04Wh Li-ion battery built to replace the original unit in Xiaomi Mi Ruby 15.6 inch Timi TM1703 and TM1802 laptops. It matches the factory form factor so installation requires no modification. Buyers needing a higher capacity cell or a different voltage will not be served by this model.

Thermal behaviour and power delivery

The pack uses high-quality Li-ion cells and a PCB designed to deliver stable capacity without false ratings. Normal operation stays within the 15.4V design envelope and the cells are rated for reliable discharge across typical workloads. No active cooling or fan is involved; heat dissipation relies on the laptop chassis. Users who need sustained high-wattage output beyond the 40.04Wh rating should look elsewhere.

Conditioning routine and storage guidance

The supplier recommends two to three full charge and discharge cycles at low current to reach full capacity. Storing the battery above 80% charge once per month preserves health during long removal periods. Avoiding continuous adapter connection while running on battery, hot or humid environments, and physical damage extends service life. The included tips cover conditioning and safety but no software or extra hardware is bundled.

Questions about this item

How do I install the KingSener N15B01W battery in my Xiaomi Mi Ruby 15.6 TM1703 TM1802, and what step is often missed?

Power off the laptop, remove the bottom case screws, disconnect the old battery connector, fit the new 15.4V 2600mAh unit, reconnect the cable, then fully charge and discharge it from low current two or three times to calibrate the cells.

What maintenance will the KingSener N15B01W Li-ion battery need later?

If the battery is removed for storage, charge it above 80% at least once per month, avoid hot or humid environments, and never leave the AC adapter connected continuously while using the battery.

What limit appears first during sustained use of the 40.04Wh KingSener N15B01W?

The 2600mAh capacity determines runtime; under continuous load the battery will deplete to low voltage before any thermal or cycle-life limit is reached.
