Replacement battery for HP Elitebook

This 11.55 V lithium-ion pack replaces the original TT03XL unit in HP Elitebook 755 G5, Elitebook 850 G5, Zbook 15u G5 and Zbook 15u G6 laptops. It delivers 56 Whr from three cells rated at 4850 mAh. The black casing matches the OEM form factor for a direct swap.

Check your current battery part number before

Verify that the original battery carries one of these codes: TT03XL, 933322-855, 932824-2C1, HSTNN-DBBK, TT03056XL-PL or 932824-421. Confirm the laptop model matches the supported Elitebook or Zbook series listed. A mismatched part number or model will prevent proper fit and function.

Thermals noise and power draw in normal use

The three-cell lithium-ion design runs cool during typical office workloads and produces no audible noise. Power draw follows the 11.55 V 56 Whr rating, so battery life scales with the laptop's own consumption profile. No active cooling is required from the host system.

Questions about this item

Does the TT03XL battery pack include installation tools or a charger?

The replacement battery ships as a standalone 3-cell lithium-ion unit. No screwdrivers, cables or AC adapter are included; reuse the original charger that came with the laptop.

My EliteBook 850 G5 lists both 933322-855 and 932824-2C1 — which part number should I order?

Both numbers refer to the same 11.55 V 56 Whr 3-cell design. This GreenTech TT03XL replaces every OEM code listed — 933322-855, 932824-2C1, HSTNN-DBBK, TT03056XL-PL and 932824-421 — so one SKU covers all variants.

What runtime can I expect from the 56 Whr rating on a ZBook 15u G6 under typical office use?

The 56 Whr capacity matches the original factory specification. Actual hours depend on screen brightness, CPU load and battery health, but the cell count and voltage are identical to the OEM pack it replaces.
