42Wh replacement battery

This 42Wh lithium-ion battery operates at 11.4V and fits Dell Inspiron 13, 14, 15 and 17 models plus Latitude and Vostro series. It replaces part numbers such as WDXOR, 3CRH3, FC92N and CYMGM. The three-cell pack is brand new and ready for installation.

Capacity and daily headroom

At 42Wh the pack delivers typical runtime for office tasks, web browsing and video playback on compatible 13 to 17 inch systems. Heavier workloads such as sustained gaming or rendering will exhaust the charge more quickly. The 11.4V rating matches the original specification so the laptop’s power management functions normally.

Lithium-ion practical limits

Lithium-ion chemistry gradually loses capacity over charge cycles and calendar time. After several hundred full cycles runtime will be noticeably shorter. The pack is not designed for user servicing and must be recycled according to local regulations when it no longer holds useful charge.

Questions about this item

Will this 11.4 V, 42 Wh battery fit alongside the original charger I already use for my Inspiron 15 5000?

Yes — the replacement matches the factory 11.4 V rating and 42 Wh capacity, so your existing Dell AC adapter will charge it normally.

How can I confirm the new WDXOR pack is healthy after installing it in my Latitude 3480?

Check the BIOS battery report: it should read 11.4 V, 42 Wh, 3 cells and show a design capacity close to 42 Wh with low wear after a few charge cycles.

Does the box include the 3CRH3 / FC92N battery only, or do I also need to buy screws or a cable separately?

The package contains the 42 Wh lithium-ion battery (about 7.25 × 3.82 × 0.23 in, 0.56 lb) — no extra screws, cables or tools are supplied.
