Replacement for Dell Latitude 7389 and 7390 2-in-1

This 7.6V 60Wh lithium-ion battery replaces part numbers K5XWW, 6CYH6, 71TG4, 725KY, N18GG and 451-BBZC. It fits Dell Latitude 13 7389, Latitude L3180, Latitude 5289 2-in-1 and Latitude 7390 2-in-1 series. It does not fit the standard Latitude 7390 non-2-in-1 model. The pack is black and contains four cells rated at 7500mAh.

Practical limits of a 4-cell 7.6V pack

Capacity is fixed at 60Wh, so runtime scales with the laptop’s power draw rather than the battery itself. The supplier rates the pack for up to 500 recharge cycles over its life. If the system does not recognise the pack on first install, reseat the connector, discharge to 10-20%, then complete three to four full charge cycles to calibrate the fuel gauge.

Upgrading from a worn original

This unit replaces an aged factory battery that no longer holds a useful charge or a lower-capacity spare that forces frequent tethering. The jump is worth it when the existing pack delivers noticeably less than the rated 60Wh or when cycle count approaches the 500-cycle design limit. Buyers needing higher capacity than 60Wh or a different voltage must look elsewhere.

Questions about this item

Which capacity should I pick for my Latitude 7389?

This battery is offered as a single 60Wh 7500mAh 4-cell pack, so there is no capacity choice to make.

What does the 7.6V rating mean once the battery is installed?

The 7.6V output matches the original Dell specification, powering the Latitude 7389, 7390 2-in-1, 5289 2-in-1 and L3180 at the correct voltage.

What connector standard does this pack use and what does it limit?

It uses the Dell proprietary connector for the listed Latitude models, limiting fitment to those exact part numbers.
