Ensure the laptop chassis matches one of the listed EliteBook or ZBook series. The supplier advises contacting them if the model is uncertain.

Questions about this item

How do I choose the right part number among CS03XL, 800513-001, HSTNN-IB6Y and the other codes listed?

Match the part number printed on your original battery to any code in the replacement list — CS03XL, 800513-001, HSTNN-IB6Y, HSTNN-UB6S, 3ICP6/65/79, 800231-141 or the other listed P/Ns — to confirm fit.

What does the 48 Wh rating mean for daily runtime on an EliteBook 840 G4?

The 48 Wh capacity at 11.4 V supplies roughly 4.2 Ah; actual runtime depends on your workload, screen brightness and power settings, but it restores the original factory capacity for the compatible models.

Does the battery use a proprietary connector or a standard interface, and what does that limit?

It uses the original HP internal connector for the EliteBook 745, 755, 840, 850 G3/G4 and ZBook 15u G3/G4 series, so it fits only those chassis and cannot be swapped into other laptop lines.
