Replacement battery for Dell Inspiron laptops

This 65 Wh lithium-ion battery replaces the original 40 Wh Dell XCMRD unit in compatible Inspiron 15 and 17 models. It operates at 11.1 V and uses six cells to extend runtime between charges. The pack is sold new and carries UL, CE, FCC and RoHS safety certifications.

Check your current battery part number

Before ordering, confirm that the original battery label shows one of the listed part numbers such as MR90Y, XCMRD, 0MF69 or any of the other codes supplied. Verify that your laptop model appears in the supported list, which covers various Inspiron 15 and 17 series units. Ensure the voltage printed on your existing pack reads 11.1 V to match this replacement.

Fits directly into the existing battery bay

The battery slots into the standard compartment without adapters or cable changes. Its black finish matches the original chassis colour. Built-in protection circuits guard against overcharge, overdischarge, overheating and short circuits. The cell chemistry is rated for up to 1000 recharge cycles over the life of the pack.

Questions about this item

Does the PISKEKAT MR90Y 65Wh battery ship with any cables, tools or installation hardware?

The listing describes only the 6-cell Li-ion battery itself; no cables, screwdrivers or mounting brackets are mentioned, so plan to reuse the fasteners and connectors from your existing Dell battery.

How do I know whether the 65Wh 11.1V version or the older 40Wh 14.8V XCMRD is correct for my Inspiron?

Match the part number on your current battery — if it reads MR90Y, XCMRD, 0MF69, 49VTP or any of the other listed codes, this 65Wh 11.1V pack is the direct replacement; the 40Wh 14.8V unit is a different voltage and not interchangeable.

What does the 65Wh 11.1V rating mean for daily runtime on an Inspiron 17 5000 series?

At 65 watt-hours the pack stores roughly 60 percent more energy than the original 40Wh Dell XCMRD, so under the same workload you can expect proportionally longer unplugged use before recharge.
