Replacement Battery for Lenovo Yoga 9 14-inch

This 75Wh lithium-ion battery replaces original part numbers including L21B4PH0, L21C4PH0, L21D4PH0 and L21M4PH0. It is built for the Lenovo Yoga 9 14IAP7 and 14IRP8 series laptops. The unit arrives new with a black finish and a 15.52V output.

Installation and System Fit

The battery slots directly into the compatible Yoga 9 chassis without adapters or cable changes. It restores the original form factor so the laptop lid closes flush and the trackpad alignment stays unchanged. No extra tools are required beyond those used for the factory battery removal.

Capacity and Runtime Limits

The 75Wh cell delivers the same rated capacity as the factory pack for typical mixed workloads. Heavy sustained loads such as video export or gaming will drain the charge faster than light browsing. The pack does not increase the maximum runtime beyond the original specification.

Questions about this item

How long does the 75 Wh capacity last under continuous load before needing a recharge?

The 75 Wh lithium‑ion pack delivers up to 75 watt‑hours of energy; actual runtime depends on the laptop's power draw during sustained use.

The battery is a passive lithium‑ion cell with no moving parts, so it produces no noise and only minimal warmth under normal loads.
