42Wh replacement for Latitude 14 7000

This 42Wh lithium-ion battery fits Dell Latitude 14 7000 series models 7480, 7490, E7480 and E7490. It operates at 11.4V using a three-cell design built to match the original DJ1J0, C27RW, PGFX4, ONFOH and 451-BBZL part numbers. The unit is new and carries CE and RoHS certification for safety compliance.

Sustained output from a three-cell pack

The three-cell lithium-ion construction delivers steady voltage across the discharge curve rather than a brief peak. This means consistent run-time during long work sessions, video playback or travel without the sharp drop-off seen in worn cells. CE and RoHS certification confirms the pack meets recognised safety and environmental standards for daily use.

Upgrade from a depleted original pack

The battery replaces an ageing or failed factory unit that no longer holds a useful charge. It is worth fitting when the original runtime has fallen below what your workflow requires. Buyers who need a higher-capacity pack or a different form factor should verify the part number against their existing battery before ordering.

Questions about this item

How much heat or power draw should I expect from the 42Wh 11.4V lithium-ion battery during all-day use?

The 3-cell 42Wh pack runs at 11.4V and produces only the heat normal for a lithium-ion cell under typical laptop loads; no active cooling is required.

What must my Dell Latitude 14 7000 7480 or 7490 already have for this 42Wh replacement to work?

Your laptop must use the original DJ1J0, C27RW, PGFX4, ONFOH or 451-BBZL 3-cell 11.4V battery; the two battery variants for these models are not interchangeable.

Will this 42Wh battery fit alongside the original chassis screws and connectors on my E7480 or E7490?

Yes — it is built to the same 3-cell 11.4V form factor as the factory unit, so the existing screw posts and motherboard connector align without modification.
