Dell Inspiron 2-in-1 replacement battery

This 40 Wh lithium-ion pack is built for Dell Inspiron 5400 2-in-1, 5406 2-in-1, 7300 2-in-1 and 7405 2-in-1 Silver models. It restores mobile power for owners whose original cell no longer holds a useful charge.

40 Wh capacity and 11.25 V operation

The four-cell design delivers 40 Wh at 11.25 V, matching the factory specification for the listed Inspiron 2-in-1 series. It will run out when the workload exceeds the cell rating, so buyers needing longer unplugged time should look at higher-capacity alternatives.

CE and RoHS certified with one-year replacement

The pack carries CE and RoHS marks confirming safety and environmental compliance. A one-year replacement warranty covers defects in materials or workmanship, and the supplier notes two different batteries exist for these models — buyers must verify the physical match before fitting.

Questions about this item

Will the 40Wh battery fit my Inspiron 5400 2-in-1 alongside the original chassis screws?

The battery is built to match the exact dimensions of the original pack for Inspiron 5400, 5406, 7300 and 7405 2-in-1 models, so the existing screw holes and latch points line up without modification.

How can I verify the 11.25V pack is delivering the rated 40Wh after installation?

Charge the laptop to 100%, then run the built-in Dell BIOS battery health check or Windows battery report; both will show the design capacity and current full-charge capacity in watt-hours.

Does the box include the 4-cell lithium-ion battery only, or are tools and adhesive strips supplied as well?

The package contains the replacement battery itself; opening tools and any required adhesive strips are not included and must be sourced separately.
