Replacement battery for Dell Latitude 7000 series

This 60Wh lithium-polymer pack replaces the original F3YGT unit in Dell Latitude 12 7000, 13 7000 and 14 7000 models including the 7280, 7290, 7380, 7390, 7480 and 7490. It also fits E7280, E7380, E7480, E7290, E7390 and E7490 series plus P28S and P73G variants. The pack is not compatible with the Latitude 7390 2-in-1 or any 42Wh three-cell battery such as DJ1J0.

Thermals noise and power draw

The four-cell 7.6V design delivers 60Wh capacity with built-in over-charge, over-discharge, over-temperature and short-circuit protection. Internal circuit boards are selected for low power consumption during charging and discharging. The manufacturer rates the pack for up to 1000 recharge cycles over its service life.

Capacity match decides fit

Only the 60Wh variant matches the original specification; the 42Wh three-cell version will not fit or function correctly. Verify the original battery part number against the supported list — DM3WC, 2X39G, 0DM3WC, 0F3YGT, 451-BBYE, 453-BBCF and KG7VF — before ordering. The package includes two screwdrivers and an installation instruction sheet.

Questions about this item

How do I install the F3Y 60Wh battery and what step is often missed?

Remove the bottom case screws using the included screwdrivers, disconnect the old 4-cell 7.6V pack, connect the new F3Y battery, then re-secure the case; the step often missed is forgetting to unplug the internal connector before lifting the old battery out.

What maintenance or replacement will the F3Y 60Wh battery need later?

The lithium-polymer pack is rated for up to 1000 recharge cycles; after that capacity will drop noticeably and a full replacement of the 60Wh unit will be required.

What limit appears first during sustained heavy use of the F3Y 60Wh battery?

The over-temperature protection circuit will trigger before the 60Wh capacity is fully drained, shutting the pack down to prevent cell damage during prolonged high-load operation.
