Compatible HP EliteBook and ZBook series

This replacement battery fits HP EliteBook 755 G5, 850 G5 and 850 G6 models as well as ZBook 15U G5 and 15U G6 units. It matches the original part numbers including TT03XL, 933322-855 and several HSTNN codes. Buyers needing a different form factor or voltage should verify their service tag before ordering.

Thermal behaviour and power draw

The lithium-ion pack operates at 11.55V with a 56Wh capacity and 4850mAh rating. Grade A cells and the integrated smart chip manage charge cycles to limit heat build-up during normal workloads. Built-in circuit protection guards against over-voltage, over-current and short-circuit conditions for stable daily use.

Included accessories and software impact

The package contains only the battery itself; no tools, screws or installation software are supplied. The smart chip communicates with the laptop firmware to report accurate capacity data without extra drivers. Users who require a multi-bay charger or diagnostic utility will need to source those separately.

Questions about this item

How do I install the TT03XL battery in my EliteBook 850 G6, and what step is often missed?

Power off the laptop, unplug the AC adapter, remove the base screws, disconnect the old battery cable before lifting it out, connect the new TT03XL cable firmly, then reassemble; the step often missed is disconnecting the battery cable before removing the old pack.

What maintenance will the 56Wh Li-ion pack need later?

No scheduled maintenance is required; calibrate once by charging to 100%, discharging to shutdown, then charging fully again, and repeat only if the fuel gauge becomes inaccurate.

What limit appears first during sustained heavy use of the 11.55V battery?

The pack will hit its thermal throttle point before voltage sag becomes critical; the built-in protection circuit shuts down output if cell temperature exceeds the safety threshold.
