Compatible Dell models

This 14.8V 40Wh lithium-ion battery replaces part numbers including XCMRD, 4WY7C and FW1MN. It fits Dell Inspiron 14 3000 series models such as 3421 and 3437, Inspiron 15 3000 series models such as 3521, 3531, 3537, 3541, 3542 and 3543, plus Inspiron 17 3721 and 3737. Latitude 3440, 3540 and Vostro 2421, 2521 are also supported.

Voltage and cycle limits

The pack delivers 14.8 volts and 40 watt-hours from four cells. It is not compatible with the 11.1V variant used in some similar chassis. Built-in circuitry protects against overcharge, overdischarge, over-temperature and short-circuit. The manufacturer rates the cell chemistry for up to 500 recharge cycles over the battery's service life.

Part-number verification

Matching the original part number printed on your existing battery is the only way to confirm fitment. Dell uses multiple battery shapes for the same laptop series, and the 14.8V XCMRD pack differs physically from the M5Y1K alternative. Cross-reference your part number against the listed codes such as 4WY7C, FW1MN, V8VNT or 312-1390 before ordering.

Questions about this item

Which capacity should I choose for my Dell Inspiron 15 3000 series laptop?

This battery is the 40Wh version; check your original battery label to confirm it lists 40Wh and 14.8V before ordering.

What does the 14.8V rating mean once the battery is installed?

The 14.8V rating matches the voltage your Dell laptop expects; using a different voltage such as 11.1V can prevent the system from powering on or charging correctly.

What interface does this battery use and what does it limit in practice?

It connects via the proprietary Dell battery connector used on Inspiron 14 3000, 15 3000, 17 3000 and Latitude 3000 series models, limiting compatibility to laptops that list part number XCMRD or the listed Dell part numbers.
