Questions about this item

How long will the 42Wh capacity last under continuous load before the battery hits its discharge limit?

The 3-cell 11.4V 42Wh pack delivers its rated capacity until the built-in protection circuit cuts off at the cell's minimum voltage threshold.

What temperature or fan noise should I expect when this battery powers a Latitude 5480 all day?

The battery itself produces no audible noise and minimal heat; any warmth or fan activity comes from the laptop's own thermal system under load.

Which Dell part numbers must already be in my laptop for this replacement to connect and charge?

It replaces Dell part numbers 3DDDG, 080JT9, 80JT9, 03VC9Y and 3VC9Y used across the Latitude 5280, 5480, 5580, 5490, 5590, 5491, 5591, 5495, 5488 and Precision 3520, 3530 series.
