A 15.4V 70Wh lithium-ion replacement battery compatible with HP ZBook X2 G4 detachable workstations

  • Battery TypeLithium-Ion
  • Extended runtime from 70Wh 4355mAh capacity
  • Stable 15.4V output for consistent performance

Genuine replacement for HP ZBook X2 G4

This lithium-ion battery is built as a direct replacement for the HP ZBook X2 G4 detachable workstation series. It matches the original 15.4V voltage and 70Wh capacity to restore factory runtime. Compatible part numbers include DN04XL, 856301-2C1 and HSTNN-DB7P. Buyers needing a battery for a different laptop model should look elsewhere.

Steady output through a full workday

The 4355mAh cell delivers consistent voltage under sustained professional workloads such as rendering or CAD. Lithium-ion chemistry maintains stable discharge without the sharp drops seen in aged packs. Capacity is rated at 70Wh for the complete charge cycle. Users who require hot-swap capability or a second battery for continuous operation will not find that feature here.

Low heat and silent operation

Normal use produces minimal warmth because the pack has no moving parts and draws power only during charging. Acoustic signature is zero in daily operation. Power draw at the wall equals the 70Wh capacity divided by charger efficiency. Systems needing active cooling for the battery itself are not supported by this design.

Questions about this item

Does the 15.4 V lithium-ion cell generate noticeable heat during extended use?

Lithium-ion chemistry at 15.4 V runs cool under normal loads; the pack is designed to match the thermal envelope of the original ZBook X2 G4 battery.

Must the laptop be a ZBook X2 G4 with a DN04XL or 856301-2C1 part number for this pack to fit?

Yes — the battery is built for ZBook X2 G4 models that originally shipped with DN04XL, 856301-2C1, HSTNN-DB7P, 856843-850, 856843-855, 856543-855, HSN-Q01C, DNO4XL, 4ICP6/60/72, DN04070XL or DN04070XL-PL.

Will the 70 Wh capacity work with the original charger supplied with the ZBook X2 G4?

The 70 Wh rating matches the factory specification, so the existing charger will charge the pack normally.
