CS03XL 48Wh replacement battery

The Batianda CS03XL is a 48Wh three-cell notebook battery built for HP EliteBook 840, 850, 745, 755 and ZBook 15u models from the G3 and G4 generations. It replaces original part numbers such as 800513-001, 800231-141, TA03XL and HSTNN-DB6U. The pack arrives new in black with two screwdrivers and an instruction manual included.

Internal circuit protection and tool kit

Integrated circuitry guards against over-charge, over-discharge and short-circuit conditions for steady daily operation. The bundled screwdrivers let you open the service hatch and swap the module without hunting for tools, while the printed manual walks through the removal and reinstallation steps.

Fixed 11.4V chemistry limits upgrade scope

The 11.4V lithium-ion layout is locked to the original platform power rails, so runtime cannot be extended beyond the 48Wh rating without a chassis redesign. Users needing higher capacity or a different voltage must look to a newer laptop platform rather than a drop-in cell swap.
