Replacement battery for Sony Vaio Duo 11

The NShi VGP-BPS31 is a new lithium-polymer battery built to replace the original pack in Sony Vaio Duo 11 models SVD11215CG and SVD11216PGB. It delivers 7.4 volts and 37 watt-hours of energy for compatible ultraportables.

37 Wh capacity and daily runtime

A 4960 mAh cell provides enough charge for typical office work and web browsing on the supported Duo 11 units. Runtime will fall short for users who need all-day operation without access to a power outlet.

Plug-and-play Li-ion interface limits

The battery uses a direct plug-in connector that matches the original VGP-BPS31 part; physical fit must be verified against the old battery before installation. It is not suitable for any laptop outside the listed Duo 11 series.

Questions about this item

Will this 7.4 V 37 Wh battery fit alongside the original SVD11215CG chassis without modification?

It is a direct plug-and-play replacement for part VGP-BPS31 and matches the Sony Vaio Duo 11 SVD11215CG and SVD11216PGB series, so it seats in the existing bay.

How can I verify the 4960 mAh pack is working correctly after the first install?

Discharge to 5 %, charge to 95 %, and repeat three to four times; the system should then report full capacity and hold charge through normal use.

What comes in the package and is any extra cable or tool required?

The box contains one VGP-BPS31 battery only; no cables, screws or tools are included.
