11.4 V 48 Wh replacement battery

This 3-cell lithium-polymer pack delivers 11.4 volts and 48 watt-hours for compatible HP EliteBook and ZBook models. It targets owners of G3 and G4 series laptops who need a fresh power source after the original cell has aged. The unit arrives new and includes two screwdrivers plus an instruction manual for immediate installation.

Fits EliteBook 840 850 745 755 G3 G4

The battery matches part numbers such as 800513-001, 854047-2C1, TA03XL and CS03046XL-PL, slotting directly into the existing bay without adapters. It frees the user from carrying a charger during typical workdays by restoring full mobile runtime. No additional hardware or firmware updates are required for the supported models listed.

Built-in protection circuits manage thermals

Over-charge, over-discharge and short-circuit safeguards keep the pack stable under normal loads, limiting heat build-up and preventing unexpected shutdowns. The low-power cell design reduces unnecessary drain, so the laptop runs cooler and quieter on battery alone. Steady voltage output supports consistent performance through everyday tasks.

Questions about this item

How long does the 48Wh capacity last before the battery needs recharging under continuous load?

The 48Wh rating measures total energy storage; actual runtime depends on the laptop's power draw and workload.

Does the 3-cell lithium-polymer pack run hot or make noise during all-day operation?

The battery has no moving parts and built-in circuit protection, so it operates silently and stays within normal temperature limits.

Which HP EliteBook or ZBook models accept the CS03XL part number without extra adapters?

It fits EliteBook 840 G3/G4, 850 G3/G4, 745 G3/G4, 755 G3/G4 and ZBook 15u G3/G4 when the original part matches the listed compatible numbers.
