Dell Latitude Green Cell Battery 5800mAh (Li-Po 7.6V) - Ref. J60J5 / MC34Y (Refurbished)

Description

The Green Cell 5800 mAh internal replacement battery (part numbers J60J5 / MC34Y / 245RR) is a refurbished spare part specially selected for the maintenance, refurbishment, and renovation of superior professional Dell Latitude E7270 and Latitude E7470 laptops. Intended for computer repair workshops, B2B IT fleet managers, and resellers specialized in refurbished hardware, this battery under a 3-month warranty restores the full original autonomy of Dell professional ultrabooks at a perfectly controlled workshop 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 5800 mAh at a nominal voltage of 7.6V for a stored energy of 55 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 Latitude 7000 series 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 on the palm rest or hand rest.

Workshop Tip & Usage

Before replacing the battery on a Dell Latitude E7270 or E7470, confirm the exact reference of the original part: the J60J5 reference corresponds to the 4-cell model (55 Wh). It is physically incompatible with earlier (Latitude E7450) or later (Latitude 7480/7490) generations. During the intervention, turn off the device, unplug the mains power supply, and remove the aluminum back cover. Disconnect the interconnection cable of the old battery with a plastic spudger without pulling on the wires 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.
