Compatible Dell Latitude models

This KingSener K5XWW battery replaces the original pack in Dell Latitude 7389, 7390 and 5289 2-in-1 systems. It matches the OEM dimensions so installation requires no modification. The part also fits the Latitude 12 5000 series and E5289 L3180 models listed by the supplier. Buyers with other Dell laptops or non-Latitude lines cannot use this unit.

Li-ion chemistry and cell quality

Six Korean Li-ion cells deliver the rated 60 Wh at 7.6 V without inflated capacity claims. The integrated PCB manages charge and discharge cycles for stable output during normal workloads. Following the supplier's conditioning advice — two or three full low-current cycles — helps the pack reach its design capacity. Users who leave the battery unused for long periods should store it above 80 % charge and top it up monthly.

60 Wh capacity decides runtime

The single figure that determines whether this part meets your needs is the 60 Wh energy rating. It defines how long the laptop can run on battery power between charges. If your workload demands more stored energy than 60 Wh provides, this battery will not be sufficient.

Questions about this item

How do I install the K5XWW battery in my Dell Latitude 7389, and what step is often missed?

Power off the laptop, remove the base screws, disconnect the old battery cable before lifting it out, connect the new K5XWW cable firmly, then replace the cover and screws. The step most often missed is disconnecting the old battery cable first.

What maintenance will the K5XWW 60Wh battery need over its life?

Fully charge and discharge it two or three times at low current when new. Avoid leaving the adapter connected constantly. Store above 80% charge if unused for a month, and keep it away from heat and humidity.

What is the first limit I will hit with the 7.6V 6-cell K5XWW under sustained heavy load?

The 60Wh capacity and 7.6V voltage set the total energy available; under continuous high drain the pack will reach its discharge cutoff first, ending runtime before any thermal limit is reached.
