Questions about this item
How long does the 4400 mAh capacity last before the voltage drops under continuous load?
The 6-cell lithium-ion pack delivers 4400 mAh at 11.1 V, rated at 49 Wh. Run time depends on the laptop's power draw; heavier workloads deplete the charge faster.
Does the battery run hot or make noise during all-day use?
The sealed lithium-ion design has no moving parts, so it produces no audible noise. Normal warmth occurs during charging or heavy discharge, but the built-in protection chip limits overheating.
Which original Dell part numbers must match for this replacement to fit?
Compatible Dell part numbers include 312-1163, 312-1164, 312-1165, 312-1310, 312-1311, 312-1324 and 312-1325. Match one of these to your original battery label.
