Replacement Battery for Dell Latitude 2-in-1 Series

The LXHY LA04 is a 7.6 V, 60 Wh lithium-ion pack built to replace the original K5XWW cell in Dell Latitude 7389, 7390, 5289 and L3180 convertibles. It delivers 7500 mAh across four cells and is rated for up to 500 recharge cycles over its service life. The unit ships new in black and weighs one pound.

Thermals Noise and Power Draw

Lithium-ion chemistry keeps self-discharge low and maintains stable voltage during typical office workloads. The pack operates at 11.55 V nominal and produces no audible noise because it has no moving parts. Heat output remains modest under normal charge and discharge rates, requiring no active cooling from the host chassis.

Included Hardware and Fitment Notes

The package contains the single battery module measuring twelve by four by one inches. It matches part numbers 6CYH6, 71TG4, 725KY, N18GG and 451-BBZC. The supplier notes that this unit does not fit the standard Dell Latitude 7390 non-convertible model, so buyers should verify the exact chassis before ordering.

Questions about this item

How do I install the LA04 battery in a Dell Latitude 7389 and which step is often missed?

Power off the laptop, unplug the AC adapter, remove the bottom case screws, disconnect the old battery cable, fit the new 4-cell pack, reconnect the cable, then replace the case screws before turning the system on.

What maintenance or replacement will the LA04 battery need over its service life?

The lithium-ion pack is rated for up to 500 recharge cycles; after that capacity drops noticeably and a full replacement is the only practical option.

What limit appears first when the LA04 runs under sustained load?

The 60 Wh capacity and 7.6 V output set the runtime ceiling; continuous heavy draw will deplete the charge before any thermal or cycle limit is reached.
