This battery replaces part numbers CS03XL, HSTNN-IB6Y, HSTNN-UB6S, 800513-001 and 800231-1C1 across the listed HP models. Buyers whose laptop uses a different part number or voltage should look elsewhere. The 12-month replacement offer and 60-day refund are handled by the seller, not the product itself.

48Wh capacity at 11.4V

The 48Wh capacity at 11.4V is the single figure that determines whether this pack matches the original specification. Verify your device's required watt-hour rating and voltage before ordering. A mismatch in either value means the battery will not work correctly.

Questions about this item

Which HP laptop models accept the CS03XL 48WH 11.4V battery?

This battery fits HP EliteBook 745 G3, 745 G4, 755 G3, 755 G4, 840 G3, 840 G4, 850 G3, ZBook 15u G3 and ZBook 15u G4.

Will the original HP charger still charge the replacement 4-cell Li-polymer pack?

Yes, the 11.4V 48WH specification matches the original CS03XL so the existing AC adapter charges it normally.

How can I confirm the new battery is delivering its rated 48WH capacity after installation?

Run a full charge cycle in the BIOS battery test or HP Support Assistant; a healthy pack should report close to 48WH and reach 100% without error.
