Direct replacement for Yoga 2 11

This 4-cell lithium-ion battery replaces OEM part numbers L13M4P21, L13L4P21, 121500223 and 121500224 in the Lenovo Yoga 2 11. It delivers 7.4V and 34WHR from a 4700mAh capacity. The unit is brand new and carries CE, FCC and RoHS safety certifications.

Voltage and capacity fixed by design

The 7.4V output and 34WHR energy rating are set by the original specification, so runtime will match the factory battery when new. Capacity cannot be increased without changing the physical pack size or cell chemistry, which this replacement does not do. Users needing longer unplugged time must carry a spare pack or use a USB-C power bank instead.

Black 4-cell pack with internal protection

The black housing fits the Yoga 2 11 battery bay without modification. Integrated circuitry provides over-voltage, over-current and short-circuit protection while maintaining low self-discharge during storage. No external charger is required; the laptop manages charging through its standard connector.

Questions about this item

Which GreenTech model fits my Lenovo Yoga 2 11 — L13M4P21 or L13L4P21?

Both L13M4P21 and L13L4P21 are listed as direct replacements for the Yoga 2 11, so either part number will fit and function correctly.

What does the 34 Wh rating mean for daily runtime on my Yoga 2 11?

The 34 Wh capacity matches the original factory specification, delivering comparable run time to the battery that shipped with the Yoga 2 11 when new.

Does the 7.4 V output limit charging speed or power delivery in any way?

The 7.4 V is the exact voltage the Yoga 2 11 expects; the system regulates charge current, so the battery charges at the standard rate designed for this laptop.
