What this battery replaces

The CS03XL is a 11.4V 48Wh lithium-polymer pack built for HP EliteBook 840, 850, 745, 755 G3 and G4 models plus ZBook 15u G3 and G4. It matches part numbers including 800513-001, 800231-141, TA03XL and CS03046XL. Buyers needing a different voltage, capacity or form factor cannot use this unit.

Fitting it into the laptop

The battery slots into the internal bay of the listed EliteBook and ZBook chassis and the package supplies a screwdriver set for the job. No extra cabling or adapter is required. Systems outside the named model list will not accept this pack mechanically or electrically.

Heat, noise and power in use

The three-cell polymer design runs silently and the built-in protection circuit manages charge current for stability. The supplier rates the pack for up to 500 recharge cycles. Thermal behaviour depends on the host laptop’s cooling; the battery itself adds no moving parts or audible noise.

Questions about this item

How long will the 48Wh capacity last before the 3-cell lithium polymer pack drops below useful runtime?

The battery is rated for up to 500 recharge cycles over its life; actual runtime per charge depends on the laptop model and workload.

Does the 11.4V lithium polymer battery run hot or make noise during all-day use?

Lithium polymer cells generate no audible noise; heat output is low under normal loads and the built-in circuit protection limits temperature rise.

Which HP EliteBook or ZBook models must I already own for this CS03XL battery to fit?

Compatible models include EliteBook 840 G3/G4, 850 G3/G4, 745 G3/G4, 755 G3/G4 and ZBook 15u G3/G4.
