  • Battery TypeLaptop Batteries
  • Extended runtime from 65WH 6-cell Li-ion design
  • Reliable power at 11.1V for compatible Dell Inspiron models

65 Wh replacement battery

This 65 Wh lithium-ion pack uses six Grade A cells at 11.1 V to replace the Dell XCMRD MR90Y unit. It fits a wide range of Inspiron 14, 15 and 17 models as well as Latitude 14 3000 and 3540 series laptops. Built-in circuit protection and CE, FCC and RoHS certification support safe, stable operation. The battery is new and ready for immediate installation.

Suits owners of listed Dell models

Buyers with an Inspiron 3421, 3521, 3721, 5421, 5521, 5721 or the 3437, 3537, 5537, 5737 variants can use this pack as a direct swap. It also matches Latitude 14 3000 and 3540 units that call for the MR90Y part number. Users of other Dell lines or non-Dell notebooks should verify their exact part number before ordering.

65 Wh capacity and six-cell headroom

The 65 Wh rating delivers a full day of typical office work, web browsing and video playback on compatible hardware. Heavier loads such as sustained gaming, rendering or virtual machines will drain the pack more quickly and may require a mid-day recharge. The six-cell layout provides consistent voltage under moderate demand but cannot extend runtime beyond the rated capacity.

Questions about this item

My Dell Inspiron 3521 still has its original 11.1 V connector — will this 65WH 6-cell battery plug straight in?

Yes, the MR90Y replaces Dell part numbers such as 0MF69, 312-1390 and XCMRD, so the existing 11.1 V connector on your Inspiron 3521 mates directly.

I plan to keep my older Dell Inspiron 14 3421 as a spare machine — does this battery support that model too?

The compatible list covers Inspiron 14 3421, 14R 5421, 15 3521, 17 3721 and Latitude 14 3000 3540, so the same pack works across those older systems.

After fitting the battery, how can I confirm the 65WH capacity is being recognised?

Check the BIOS or Windows battery report — it should show a design capacity of 65WH at 11.1V with six cells and no error flags from the built-in protection circuit.
