Cameron & Co 5.7 Ah HP EliteBook battery

This new Cameron & Co lithium-polymer battery replaces the original HP BE06XL unit in EliteBook 1040 G4 models. It delivers a 5.7 Ah capacity in a black housing and is built for owners who need a direct replacement for a worn or failed internal pack.

Installation fits the 1040 G4 chassis

The pack slots into the existing battery bay without tools or soldering; the connector aligns with the motherboard header used by part numbers 918180-855 and HSTNN-1B7V. Common issues arise when the old battery has swollen and distorted the bay, preventing the new pack from seating fully or causing the latch to misalign.

Verify your exact 1040 G4 sub-model

Check the product label on the base of the laptop for one of the listed part codes such as 1EM81EA, 1EP15EA, 2TL68EA or 2UL91UT before ordering. This battery is not suitable for other EliteBook series, Folio models outside the 1040 G4 line, or any device requiring a different voltage or connector layout.
