Compatible Laptop Battery

This 56Wh lithium-polymer replacement battery fits HP EliteBook 755 G5, EliteBook 850 G5 and G6, plus ZBook 15U G5 and G6 models. It replaces original part numbers including TT03XL, HSTNN-DB8K and HSTNN-LB8H. The unit ships new in black with an 11.55V output rating. Buyers needing a different form factor or higher capacity should look elsewhere.

Thermals and Power Draw

The 4850mAh cell delivers standard run-time for supported ultrabooks under typical office workloads. Lithium-polymer chemistry helps maintain stable voltage during discharge without excessive heat buildup. No active cooling is required as the pack sits inside the chassis. Users running sustained heavy compute loads will see shorter battery life.

Included Parts and Fit

The package contains only the battery itself; no tools, screws or installation guides are supplied. Compatibility covers the listed EliteBook and ZBook 15U generations using part numbers 932824-141, 932824-2C1 and 933322-855. It does not fit other HP series or non-listed chassis. Professional installation is recommended if the service manual calls for adhesive removal.

Questions about this item

How do I install the TT03XL battery in my EliteBook 755 G5, and what step is often missed?

Power off the laptop, remove the bottom cover screws, disconnect the old battery connector before lifting it out, then connect the new battery before refitting the cover.

What replacement will the 56Wh Li-polymer battery need over time?

The battery itself will need replacing once its capacity drops below a useful level; Li-polymer cells are not user-serviceable.

What limit appears first during sustained use of the 11.55V 4850mAh pack?

Thermal limits throttle performance before the voltage cut-off is reached, especially under heavy multi-core loads.
