Dr. Battery SS03XL 25.4Wh replacement

This new Dr. Battery Professional Series lithium polymer battery replaces the original power source in compatible HP EliteBook and ZBook laptops. It is built for business professionals and mobile workstation users who need dependable runtime during office work and travel. OEM-grade cells deliver stable performance and long cycle life. Built-in protection guards against over-charging, over-discharging, overheating, and short-circuit conditions.

Capacity and voltage headroom

The battery provides 25.4 Wh at 11.55 V with a 2200 mAh rating, supplying enough energy for typical productivity tasks and meetings away from a desk. Runtime decreases under sustained heavy workloads such as rendering or large dataset processing. Users who require all-day operation without recharging will find the capacity limiting.

Lithium polymer cell constraints

Li-polymer chemistry offers a slim 8.0x1.5x0.8 cm form factor that fits the internal bay of the listed EliteBook and ZBook models. Capacity naturally diminishes over repeated charge cycles, eventually requiring another replacement. The pack is not compatible with laptops outside the specified part-number list, including other HP series or non-HP devices.

Questions about this item

Will the 11.55 V Dr. Battery SS03XL work alongside the original 45 W AC adapter I already use with my EliteBook 840 G5?

Yes — the replacement cell is rated at 11.55 V, matching the voltage your EliteBook 840 G5 expects, so the existing 45 W adapter will charge it normally.

How can I verify the new 2200 mAh pack is recognised correctly after I install it?

Power on the laptop, open the HP BIOS or Windows Battery Report, and confirm the reported design capacity shows 25.4 Wh and the part number reads SS03XL.

Does the box include a screwdriver or installation guide for the 8.0×1.5×0.8 cm battery?

The package contains only the battery itself; any Torx or Phillips drivers and the service manual for your specific EliteBook or ZBook must be sourced separately.
