Replacement Battery for Dell Inspiron and Latitude

This 65Wh lithium-polymer pack operates at 11.1V and replaces Dell part numbers such as MR90Y, 0MF69, 49VTP and 312-1390. It fits Inspiron 14, 15 and 17 models including the 3421, 3521, 3721, 5421, 5521 and 5721 series as well as Latitude E3440 and E3540 units. The cell chemistry is rated for about 500 recharge cycles.

Suitable for owners of listed Dell notebooks

Buyers whose laptop model does not appear in the compatibility list should look elsewhere. The battery is not intended for ultrabooks or gaming chassis that require a different form factor or voltage. Systems needing a higher or lower capacity than 65Wh will not be served by this unit.

Built-in protection circuits

Overcharge and over-discharge safeguards are integrated into the pack, and the unit carries CE, FCC and RoHS marks. No extra cables, tools or software are included in the package. The certifications and circuitry changes mean the battery can be installed and used immediately without additional configuration.

Questions about this item

Which Dell laptop models must I already own for this 65Wh 11.1V battery to fit?

It fits Dell Inspiron 14 3421 3437 5421 5437, Inspiron 15 3521 3531 3537 3542 5521 5537, Inspiron 17 3721 3737 5721 5737 M731R-5735 M531R-5535, Latitude E3440 E3540 and Vostro 2421 2521.

Will this MR90Y replacement work alongside the original Dell AC adapter I still use?

Yes, the 11.1V Li-Polymer pack charges normally from the factory Dell charger; the built-in over-charge and deep-discharge protection circuits handle the same voltage range as the original 0MF69 49VTP 68DTP packs.

How can I confirm the battery is healthy after the first few charge cycles?

Expect roughly 500 full recharge cycles over its life; after initial calibration the OS should report near 65Wh design capacity and hold charge without sudden shutdowns.
