Direct replacement for Yoga 2 11

This Cameron Sino lithium-polymer battery is built for the Lenovo Ideapad Yoga 2 11 series, including the 20332, 20428 and 2332 model numbers. It matches the original 121500224, L13L4P21 and L13M4P21 part numbers so the laptop recognises it without BIOS updates or adapter cables. The pack is aimed at owners whose factory cell no longer holds a useful charge and who want a drop-in spare rather than a full device replacement.

Thermals and power draw

The 7.4 V, 4.6 Ah cell delivers 34.04 Wh of energy in a 173.67 x 121.93 x 5.95 mm black housing that fits the existing bay. Lithium-polymer chemistry keeps self-discharge low and does not require scheduled calibration cycles. Under normal office workloads the pack runs cool and silent because there are no moving parts and no active cooling to manage.

Upgrade context

This unit restores the original runtime rather than extending it, so buyers who need more hours per charge than the factory design provided will not gain extra capacity. It is not suited to models outside the listed Yoga 2 11 family or to systems that require a different voltage or connector layout. The jump is worth it when the existing battery has degraded below 100 % health and a reliable OEM-compatible replacement is preferred over used or unbranded alternatives.

Questions about this item

How do I install the DS-CS-LVY211NB battery in my Lenovo Ideapad Yoga 2 11, and what step is often missed?

Power off the laptop, remove the bottom case screws, disconnect the old battery connector, fit the new 173.67 x 121.93 x 5.95 mm pack, reconnect the cable firmly, then reassemble; the step often missed is ensuring the connector clicks fully into the motherboard socket before closing the case.

What maintenance or replacement will the Li-Polymer 4.6 Ah battery need over time?

Li-Polymer cells require no scheduled maintenance; capacity will gradually fade after several hundred charge cycles, so plan to replace the pack when run-time drops below your needs — typically after two to three years of daily use.

What limit appears first during sustained use of the 7.4V 34.04 Wh battery?

The 4600 mAh capacity is the first limit; under continuous load the pack will deplete in a few hours, and voltage will sag as the state of charge falls, reducing run-time before thermal limits become a factor.
