Is your Dell Inspiron not holding a charge like it used to?

Grab this 5200mAh replacement battery and get back to untethered computing.

It's a 6-cell, 11.1V lithium-ion unit that fits a ton of models: Inspiron 15R 3521, 5521, 5537, and even some Latitude and Vostro lines.

We're talking part numbers like MR90Y, G35K4, N121Y, and a whole bunch more (check the full list—it's huge).

It's brand new, unbranded but built to spec, and ships from China.

The best part?

It comes with a 5-year warranty, so you're covered for the long haul.

Color is standard black, and it's a straightforward swap—just pop out the old one and slide this in.

Don't forget, it's got that California Prop 65 heads-up, but that's standard for these cells.

Reliable power for when you're on the move.
