Green Cell 3DDDG 11.4V 2900mAh battery for Dell Latitude 5280 / 5290 / 5480 / 5490 / 5495 / 5580 / 5590

Description

The Green Cell compatible 3DDDG replacement battery is a reliable and cost-effective refurbishment solution for IT repairers, refurbishers, and IT support services. Specially developed to fit into 12 to 15-inch Dell Latitude series professional laptops, this battery offers a direct alternative to original parts, allowing you to eliminate power failures, unexpected shutdowns, or loss of autonomy caused by the natural wear of Lithium-Ion cells.

Designed by the specialist manufacturer Green Cell, this battery incorporates high-density Lithium-Ion polymer cells delivering a nominal voltage of 11.4 Volts for a capacity of 2900 mAh (33 Wh). Its BMS (Battery Management System) control electronics ensure smooth communication with the power controller (EC) and the motherboard's BIOS/UEFI, avoiding startup warning messages regarding unrecognised batteries. The battery also incorporates advanced electronic protections against overvoltage, deep discharge, overcharging, and overheating, thus preserving the integrity of the laptop's internal components.

The "short" 3-cell physical format specific to the 3DDDG reference provides a decisive mechanical advantage for 14 and 15-inch chassis (Dell Latitude 5480, 5490, 5580, 5590): it does not extend across the entire width of the lower bay. This design leaves the necessary space for the installation or retention of a 2.5-inch SATA hard drive or SSD, offering superior storage flexibility compared to large-format 4-cell batteries (GJKNX type) which block this slot.

Workshop Advice & Usage

Before working on the device, you must unplug the mains charger and press the power button for 5 seconds to discharge residual static electricity from the circuit board. When positioning the battery, gently insert the ribbon connector into the motherboard's keyway without forcing it to avoid damaging the BMS data transmission pins. After reassembly, it is recommended to perform a full calibration cycle: charge the battery to 100% without interruption, leave the computer plugged in for about an additional hour, then let it discharge on battery until automatic shutdown before performing a new full recharge.
