Questions about this item

Does the 71TG4 battery match the exact dimensions and connector for my Latitude 5289 2-in-1?

This 11.4V 45Whr 3-cell pack is built to the OEM 71TG4, X49C1 and CFX97 specifications, so it fits the Latitude 5289, 7389 and 7390 2-in-1 chassis without modification.

What is the correct installation sequence to avoid a « battery not detected » error?

Power off the laptop, disconnect the AC adapter, remove the base cover, unplug the old battery cable first, then connect the new 71TG4 cable before refitting the cover and applying AC power.

How will I know when this 3947mAh pack needs replacing?

When a full charge no longer delivers the rated 45Whr runtime or the system reports a significant capacity loss, the lithium-ion cells have reached end of life and the battery should be swapped.
