Dell Latitude / Precision Green Cell Battery 6000mAh (Li-Po 7.6V) - Ref. GJKNX (Refurbished)

Description

The Green Cell 6000 mAh internal replacement battery (part number GJKNX / 0GJKNX) is a refurbished spare part specially selected for the maintenance, refurbishment, and renovation of a very wide range of professional Dell Latitude laptops (5280, 5290, 5480, 5490, 5491, 5495, 5580, 5590, 5591 series) and Dell Precision mobile workstations (3520, 3530). Intended for computer repair workshops, corporate IT fleet management services, and B2B resellers specializing in refurbished hardware, this battery, covered by a 3-month warranty, restores the original battery life of professional Dell computers at a controlled equipment cost.

Electrochemicaly, this refurbished module integrates an assembly of 4 high-density Lithium-ion Polymer (Li-Po) cells of the Green Cell brand, delivering a capacity of 6000 mAh at a nominal voltage of 7.6V for a stored energy of 68 Wh. This configuration provides a perfectly regulated electrical power supply to the motherboard and supports up to 500 complete charge and discharge cycles. The whole unit is managed by an intelligent electronic management circuit (BMS - Battery Management System) responsible for the continuous control of the charging current. This controller protects the component and the computer against overvoltages, deep discharges, short circuits, and thermal runaway risks.

The ultra-flat external casing is molded in a heat-resistant high-density insulating polymer, rigorously adapted to the internal footprint of Dell chassis. Integration is carried out under the bottom cover of the computer and interfaces with the motherboard via a secure flat ribbon connector. The location of the metal fixing eyelets faithfully respects the original assembly points to guarantee rigid fastening without exerting mechanical stress under the palm rest.

Workshop Tip & Usage

Before installing this battery, you must check the storage configuration of the client's PC: the 68 Wh version (4 cells, Ref. GJKNX) occupies an extended internal surface. On 15-inch chassis (Latitude 5580/5590/5591 and Precision 3520/3530), its dimensions require the exclusive use of an M.2 SSD storage format and block the physical slot reserved for 2.5-inch SATA hard drives. Before intervention, turn off the device, unplug the mains power supply, and remove the bottom cover. Disconnect the power ribbon cable of the old battery with a plastic spudger so as not to damage the motherboard connector. During initial workshop commissioning, perform a complete calibration cycle: charge the refurbished battery to 100% under mains power, then let the device discharge gradually to about 10-15% before performing an uninterrupted recharge.
