New 11.4V 42Wh WY9DX Laptop Battery For Dell Latitude 5420 5520 - RJ40G 005R42 Compatible

If your Dell Latitude 5420 or 5520 isn't holding a charge like it used to, this new replacement battery is exactly what you need.

It's the WY9DX model, which is the direct fit for those laptops.

Brand new, never used, still in its packaging.

\n

Specs-wise, it's 11.4 volts, 42Wh (which is about 3500mAh), and it's a lithium-ion battery with 3 cells.

So you're getting the same capacity as the original.

It's black, made in China, and compatible with the Latitude 5420 and 5520 series.

If your original part numbers were RJ40G or 005R42, this one's got you covered.

\n

It's an unbranded generic battery, but hey, it does the same job for way less money than the official Dell one.

Comes with a 1-year warranty too, so you're not taking a huge risk.

Just pop out your old battery, slide this one in, and you're back to using your laptop unplugged again.

No more hunting for an outlet every 20 minutes.
