Direct replacement for Dell Inspiron and Latitude

This 40WH lithium-ion battery operates at 14.8V using a 4-cell design and matches the original XCMRD form factor. It is built for Dell Inspiron 14, 15 and 17 models as well as Latitude 14 and 15 3000 Series and selected Vostro units. The pack ships new in black with an instruction sheet.

Fits existing chassis without modification

The battery slides into the standard bay on compatible Dell laptops and connects to the stock motherboard header. No extra cabling, adapter or firmware update is required. It frees the user from a degraded original pack and restores untethered operation for daily workloads.

Rated for up to 1000 recharge cycles

At 40WH capacity the pack delivers typical office and web browsing runtime before needing a recharge. It will not extend runtime beyond the original specification and is unsuitable for users who need higher-capacity alternatives or support for models outside the listed Dell series.

Questions about this item

How long does the 40WH capacity last under continuous load?

The 40WH rating provides a specific energy capacity; actual runtime under sustained use depends on the laptop model and workload.

Does the 4-cell 14.8V design run hot or loud during all-day operation?

The battery itself has no moving parts and generates minimal heat; system thermals and fan noise are managed by the laptop, not the battery.

Which Dell laptop models are confirmed compatible with the XCMRD part number?

It fits Dell Inspiron 14 3421 3437 5421, Inspiron 15 3521 3531 3537 5521, Inspiron 17 3721 3737 5737, Latitude 14 3000, Latitude 15 3000, Latitude 3440 3540 and Vostro 2421 2521.
