What this battery replaces

This NShi 02DL021 unit is a direct replacement for the original Lenovo Yoga X390 battery. It matches the 11.52V, 51Whr specification and the three-cell lithium-ion layout used in the 20NN and 20NQ chassis variants. Owners of those models can swap the pack without adapter changes.

Build and daily fit

The black casing follows the OEM footprint so the battery seats flush in the existing bay and the connector aligns with the motherboard header. No screw-hole modification or cable routing is required, and the pack locks with the original latch mechanism. Buyers who need a higher-capacity cell count or a different voltage platform will not be served by this part.

Thermals and power behaviour

The 4372mAh cell group delivers the rated 51Whr at 11.52V, drawing current within the laptop’s native charge controller limits. Under typical office loads the pack runs at chassis temperature and produces no audible noise. It is certified to CE, FCC and RoHS standards, and each unit is tested for stable voltage, circuit protection and low self-discharge before dispatch.
