Replacement battery for Yoga Slim 7 ProX 14

This new lithium-ion unit is built as a direct replacement for the Yoga Slim 7 ProX 14ARH7 and 14IAH7 series. It matches the original 4-cell configuration and 15.52 V operating voltage. Owners of compatible Lenovo ultraportables can restore factory runtime without adapter modifications.

Capacity and runtime envelope

The pack stores 4571 mAh at 15.52 V, delivering the same watt-hour rating the laptop was designed around. Typical mixed workloads should see original battery life; sustained heavy compute or high screen brightness will deplete the charge faster. The four-cell layout limits maximum capacity, so users needing multi-day unplugged sessions will find the ceiling restrictive.

Installation and system integration

The battery fits the internal bay using the existing screw points and connector; no extra cables or firmware steps are required. It replaces OEM part numbers including 5B11F52556, 5B11H31568, L21C4PC4 and L21M4PC7. The design frees the chassis from a swollen or exhausted original cell, but it does not add charging circuits or change the laptop's power-management behaviour.

Will the 5B11F52558 battery work with the original charger on my Yoga Slim 7 ProX 14ARH7?

How can I confirm the 5B11F52558 is recognised correctly after installation?

Does the 5B11F52558 package include installation tools or just the battery?
