Questions about this item
Will the 11.1 V output match the original Dell Precision M2400 power rail without BIOS changes?
The replacement is rated at 11.1 V and 4400 mAh, matching the factory specification for the Precision M2400, M4400 and M4500 workstations.
How can I confirm the smart control chip is balancing the 6 lithium-ion cells after the first charge?
A full charge should report roughly 49 Wh in the Dell Power Manager utility and the battery LED sequence will show a steady charge-complete pattern.
Does the package include the 312-7414 mounting screws or must I reuse the originals?
Only the 6-cell 11.1 V battery is supplied; all screws, brackets and the AC adapter are reused from the existing Dell Latitude or Precision chassis.
