Questions about this item

How long will the 4400 mAh capacity last before the voltage drops under heavy load?

The 6-cell lithium-ion pack delivers 11.1 V and 49 Wh, so runtime under sustained load depends on the laptop's power draw; higher draw shortens the usable window before voltage sag.

Does the pack run hot or loud during all-day operation?

The battery has no moving parts and produces no noise; heat rises with charge and discharge rates, but the built-in protection chip manages over-temperature conditions.

Which original Dell part numbers must match for this replacement to fit?

Compatible part numbers include FU274, FU439, NM631, KY265, PT434, W1193, 1M215, 312-0748, 312-0749, 312-0753, 312-0754 and 312-0910.
