Direct replacement battery for HP EliteBook

This Dr. Battery Professional Series unit replaces original HP batteries including part numbers 933321-855, 932823-1C1 and HSTNN-IB8C. It fits EliteBook 830 G5, 840 G5, 836 G5, 846 G5 and ZBook 14u G5 laptops. The lithium-polymer pack is built with OEM-grade cells for stable voltage and long cycle life. Confirm your original part number and voltage before ordering.

25.4 Wh capacity at 11.55 V decides runtime

The pack stores 25.4 Wh of energy at a nominal 11.55 V, delivered by a 2200 mAh lithium-polymer cell array. This capacity figure is the single specification that determines whether the battery will meet your daily unplugged workload. Match it against the Wh rating printed on your factory battery to ensure the correct replacement.

Sustained output with built-in protection circuits

Under continuous load the internal protection logic guards against over-charging, over-discharging, overheating and short-circuit conditions. The OEM-grade cells maintain steady voltage through a full workday rather than sagging after a short burst. The slim 8.0×1.5×0.8 cm form factor fits the original bay without modification.

Questions about this item

How long will the 25.4 Wh rating actually run my EliteBook 840 G5?

The 25.4 Wh capacity translates to roughly 2.2 Ah at 11.55 V; real-world runtime depends on your workload, screen brightness and power settings, but it restores the original factory battery life for this model.

Does the 11.55 V output match the original HP SS03XL specification?

Yes, the battery delivers 11.55 V, which is the exact voltage used by the HP SS03XL and all listed part numbers such as 933321-855 and HSTNN-IB8C.

Will the 8.0 x 1.5 x 0.8 cm form factor fit inside my EliteBook 836 G5 without modification?

The dimensions match the OEM battery cavity for the EliteBook 836 G5 and the wider 840/846 series, so it installs directly using the existing screws and latches.
