Replacement Battery for HP EliteBook and ZBook 14U

This 50Wh lithium-ion battery replaces part numbers including SS03XL, 933321-855, HSTNN-LB8G and HSN-I13C-4. It fits HP EliteBook 840 G5 G6, 730 735 740 745 830 846 G5, 735 745 830 G6, ZBook 14U G5 G6 and MT44 Mobile Thin Client models. The 3-cell pack delivers 11.55V and 4330mAh capacity.

Upgrade from degraded original cells

When an original pack no longer holds a useful charge this unit restores full runtime without modifying the chassis. The jump is worth it when the laptop shuts down early, reports a capacity warning or physically swells. Certified to UL CE FCC RoHS standards, it includes overheat, short-circuit and overload protection for safe operation.

50Wh capacity for typical business workloads

The 4330mAh rating comfortably handles office applications, web browsing and video playback through a standard workday. Heavy multi-core rendering, sustained GPU compute or maximum screen brightness will drain the pack faster. Users needing multi-day autonomy or hot-swap capability should consider a secondary power source.

Questions about this item

Will the SS03XL 933321-855 fit the battery bay of my HP EliteBook 840 G5 without modification?

Yes — the battery is built to the original SS03XL form factor and matches the 11.55 V, 50 Wh specification used in the EliteBook 840 G5, 840 G6, 730 G5, 735 G5, 740 G5, 745 G5, 836 G5, 846 G5, 735 G6, 745 G6, 830 G6, ZBook 14U G5, ZBook 14U G6 and MT44 Mobile Thin Client.

What is the most common installation mistake with the SS03XL 933321-855?

Forgetting to disconnect the old battery connector from the motherboard before removing the bottom cover screws; the service manual requires the connector to be unplugged first to avoid a short circuit.

How long will the 3-cell 50 Wh Li-ion pack last before it needs replacing?

Capacity gradually declines with each charge cycle; when run-time no longer meets your daily workload, swap in a new SS03XL-compatible pack.
