Compatible Lenovo ThinkPad X390 Yoga Battery

This replacement battery fits the Lenovo ThinkPad X390 Yoga and matches part numbers 02DL021, 02DL022, 5B10W13927 and L18L3P72. It is built for owners of those specific models who need a direct swap. Buyers with other ThinkPad series or non-Lenovo laptops cannot use this unit.

Li-Polymer Chemistry and 47.23 Wh Capacity

The lithium-polymer pack delivers 4.1 Ah at 11.52 V for 47.23 Wh of energy. Internal resistance stays low during typical office workloads, so the laptop runs cool and the fan remains quiet. No separate thermal management is required beyond the notebook's own design.

Slim 6.35 mm Profile and Black Finish

At 6.35 mm thick the cell sits flush inside the X390 Yoga chassis without forcing the base or trackpad. The black housing matches the original aesthetic and the connector aligns with the motherboard header for a secure click. No extra cables or adapters are needed for daily use.

Questions about this item

How do I install the DS-CS-LVT390NB battery in a ThinkPad X390 Yoga, and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the bottom case screws, unplug the old battery connector before lifting it out, then connect the new 11.52 V 4100 mAh pack and reassemble; the step most people skip is unplugging the old battery first.

What maintenance or replacement will the DS-CS-LVT390NB need over time?

As a Li-Polymer pack it requires no scheduled maintenance; plan to replace it once runtime drops below your needs, typically after several hundred charge cycles.

What limit appears first during sustained use of this 4.1 Ah battery?

The 47.23 Wh capacity sets the runtime ceiling; under continuous load the pack will deplete before any thermal or voltage limit is reached.
