Green Cell F3YGT 7.6V 6800mAh Battery for Dell Latitude 7280 / 7290 / 7380 / 7390 / 7480 / 7490

Description

The Green Cell F3YGT compatible replacement battery is a high-performance power solution intended for maintenance technicians, refurbishers, and corporate IT departments. Designed to restore the original battery life of professional ultrabooks in the Dell Latitude 7000 range (12.5", 13.3", and 14"), this internal battery helps resolve critical power failures, rapid charge loss, and malfunctions linked to the premature wear of original cells.

This model relies on a high-density 4-cell Lithium-Ion Polymer chemistry, delivering a nominal voltage of 7.6 Volts for a capacity of 6800 mAh (approximately 52 Watt-hours). Its integrated BMS (Battery Management System) electronic controller ensures perfect backward compatibility with Dell motherboard power protocols, guaranteeing immediate recognition by the BIOS/UEFI and avoiding the display of warning messages at startup. The internal architecture incorporates hardware protections against overcharging, excessive discharging, thermal rises, and short circuits.

The high-density ABS polymer casing is moulded to the exact dimensions of the original chassis to ensure perfect alignment of the mounting points and the connection ribbon cable. As the F3YGT reference corresponds to the large 4-cell format, it occupies the entire lower battery compartment across the width of the laptop, offering maximum energy capacity for mobile users with high battery life requirements.

Workshop Advice & Usage

Before performing the replacement on the chassis, you must disconnect the mains power supply and hold the power button down for 5 seconds to discharge residual static electricity from the circuit board. Check the space available in the battery compartment: as the 4-cell F3YGT model occupies the entire width, ensure that no 2.5-inch hard drive is present in the adjacent bay (the use of an M.2 SSD is required with this format). When connecting the ribbon cable to the motherboard connector, insert it perfectly straight without forcing the pins to prevent any poor contact of the battery management SMBus. To optimize cell life and calibrate the operating system's charge indicator, perform an initial uninterrupted charge to 100%, leave the device plugged in for an additional hour, then let it discharge during continuous use until it shuts down before a full recharge.
