Replacement battery for Yoga 2 Pro 13.3

This GreenTechLLC battery replaces the original Lenovo unit in the Yoga 2 Pro 13.3" laptop. It delivers 7.4V and 54Wh through a 4 cell lithium-ion pack. The part suits owners who need a fresh power source for this specific ultrabook model. Buyers with different Lenovo series or screen sizes should look elsewhere.

Check your current part number before ordering

Verify that the original battery carries one of these codes: L12M4P21, L13S4P21, 121500225 or 121500156. Confirm the laptop shows 7.4V on the old label. Ensure the machine is a Yoga 2 Pro 13.3" and not a later revision. The connector layout matches the factory design, so no adapter is required.

Black 4 cell pack with tested safety circuits

The black enclosure measures 11 X 5 X .3 inches and weighs .95LB. Each unit is tested for correct voltage, circuit protection, stable current and low self-discharge. CE, FCC and RoHS certifications cover electrical safety. The slim profile fits the original bay without forcing the chassis. Daily use feels identical to the OEM battery.

Questions about this item

Does the battery arrive with any tools or screws, or must I supply them?

The package contains only the 4-cell lithium-ion battery; installation tools and screws are not included.

Which part number matches my Yoga 2 Pro 13.3″ — L12M4P21 or L13S4P21?

Both L12M4P21 and L13S4P21 are listed as direct replacements, so either matches the 13.3″ model.

What runtime can I expect from the 54 Wh rating in daily use?

The 54 Wh capacity restores the original factory runtime for the Yoga 2 Pro 13.3″ under typical mixed workloads.
