4GVMP 7.6V 68Wh laptop battery for Dell Latitude 5400 5500 Precision 3540 Inspiron 7590 7591 7791 2-in-1

Compatible Dell 2-in-1 Replacement

The 4GVMP lithium-ion battery replaces the original pack in Dell Latitude 5400, Latitude 5500, Precision 3540, Inspiron 7590 2-in-1, Inspiron 7591 2-in-1 and Inspiron 7791 2-in-1 models. It is not compatible with the standard Inspiron 7590, 7591 or 7791 series. The pack uses four cells and delivers 7.6 volts at 68 watt-hours. Installation is supported by the included screwdrivers and instruction sheet.

Sustained Capacity Behaviour

Rated at 68 watt-hours and 8500 milliamp-hours, the battery supplies power for approximately three to six hours per charge depending on workload. Under continuous load the voltage remains stable at 7.6 volts until the protection circuit triggers shutdown. The lithium-cobalt chemistry maintains consistent output across the discharge curve without sudden voltage sag.

Thermals and Power Draw

Multi-protection circuitry guards against short circuits, overheating and overload during normal operation. The pack weighs 78 grams and fits the existing chassis without modification. Power consumption matches the original specification so the laptop's thermal profile and fan behaviour remain unchanged. No external adapter is required beyond the standard 20 volt 11.8 ampere unit.
