Replacement battery for ThinkPad X390 Yoga

This 51Wh lithium-ion unit replaces Lenovo part numbers L18L3P72, L18M3P72, 02DL021, 02DL022 and SB10K97659. It is built for owners of the ThinkPad X390 Yoga who need a new power source. Buyers with other laptop models cannot use this battery.

Thermals, noise and power draw

The battery operates at 11.55V and produces no fan noise because it has no moving parts. Heat output stays low during normal office work and web browsing. Power delivery is steady for the rated capacity.

Behaviour under sustained load

The 51Wh capacity supports extended sessions away from a mains outlet. Voltage remains stable through long discharges without the sharp drops seen in worn cells. Users who need more runtime than 51Wh provides should consider a higher-capacity option if one exists for this chassis.

Questions about this item

How do I install the L18L3P72 battery in my ThinkPad X390 Yoga and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the bottom case screws, detach the old battery connector, fit the new 11.55 V 51 Wh pack, reconnect the cable, replace the case and screws, then charge fully before first use.

What upkeep will this 51 Wh lithium-ion battery need over time?

No user-serviceable parts exist; capacity will gradually fade with charge cycles, so plan to replace the pack when runtime no longer meets your needs.

What limit appears first during sustained use of this 11.55 V battery?

Thermal throttling or reduced runtime will occur as the cells age and internal resistance rises under continuous load.
