Replacement Battery for Dell Latitude 2-in-1

The NShi 71TG4 is a new lithium-polymer battery built for Dell Latitude 5289, 7389 and 7390 2-in-1 notebooks. It replaces part numbers 71TG4, 071TG4, K5XWW, X49C1 and 0X49C1. The pack carries CE and FCC certification.

Voltage and Connector Match

The single specification that decides fit is the 11.4V output combined with the exact connector layout shown in the product images. If the original battery reads 11.4V and the connector matches, this unit will seat and communicate correctly; a different voltage or pin arrangement means it will not work.

Capacity and Runtime Headroom

Rated at 45Wh and 3745mAh, the cell delivers a full day of typical office use on a single charge. Heavy workloads such as continuous video playback or virtual machines will drain it faster, so users who need more runtime should keep a charger nearby.
