Exact-fit replacement for Xiaomi Mi Air 13.3

This KingSener R13B02W lithium-polymer battery is built as a direct replacement for the Xiaomi Mi Air 13.3 inch series, including models equipped with the fingerprint reader. It restores the original 7.6V 5230mAh capacity in a black pack that matches the factory form factor. The cell is manufactured in China and supplied new with a two-year warranty.

Voltage and capacity must match 7.6V 5230mAh

The single specification that decides compatibility is the 7.6 volt 5230 milliampere-hour rating, which equals 39 watt-hours. Only a pack with these exact electrical values will communicate correctly with the laptop's power management and deliver the expected runtime. A different voltage or capacity will cause charging errors or reduced battery life.

Simple swap but verify the part number first

Installation requires opening the chassis and disconnecting the old pack, a routine procedure for this ultrabook series. The most common issue is ordering the wrong variant; confirm the sticker on your original battery reads R13B02W or R13B01W before fitting the new unit.

Questions about this item

How long will the 39WH capacity actually run my Xiaomi Mi Air 13.3" laptop?

The 39WH rating matches the original specification, so real-world runtime will be equivalent to a factory-fresh battery under the same workload and brightness settings.

Does the 7.6V lithium-polymer pack use the same connector and pinout as the stock R13B01W unit?

Yes, it is built to the exact 7.6V Li-polymer spec and replaces both R13B01W and R13B02W part numbers with identical connector geometry.

Will this battery fit the fingerprint-reader version of the Mi Air 13.3" chassis without modification?

The pack is confirmed 100% compatible with the fingerprint-equipped Mi Air 13.3" series, so it seats in the original bay using the existing screw points.
