Dell Battery 3C 11,4V 4250mAh 51Wh

Dell D4CMT is a rechargeable lithium-ion replacement battery for compatible Dell notebooks. Its three-cell design and 51 Wh energy capacity provide notebook power for mobile work when a replacement battery is needed.

Dell specifies a charge capacity of 4254 mAh and an output voltage of 11.4 V DC. These ratings identify this D4CMT variant for notebook use; it is not a general-purpose external battery.

Dell lists the Latitude 5280, 5480, 5580, 5488, 5290, 5490, 5491, 5495, 5590 and 5591, plus the Precision 3520 and 3530, as compatible systems. In these models, the D4CMT can replace the battery to support notebook use away from a fixed power connection.
