Compatible replacement battery

The POWER-FENG DB5D is a 42Wh lithium-polymer battery rated at 11.1V and 3700mAh. It replaces original part numbers including BL06XL, HSTNN-DB5D, HSTNN-IB5D, 722236-1C1, 722236-2C1 and 722297-001. Designed for HP EliteBook Folio 1040 G1 and G2 models.

Direct OEM swap

The unit fits the listed EliteBook Folio models without adapters or cable changes. No driver installation or firmware update is required; the system recognises the battery immediately. It restores mobile operation for units whose original packs no longer hold charge.

Proprietary form-factor limit

The pack uses a model-specific connector and chassis shape that only matches the named Folio 1040 generations. It cannot be used in other HP series, newer EliteBooks or third-party laptops. Buyers needing a different voltage, capacity or physical layout must source the correct part for their device.

Questions about this item

Does the 42Wh Li-polymer pack require any periodic maintenance or scheduled replacement beyond normal charging?

The battery is a sealed Li-polymer unit with no user-serviceable parts; it only needs replacement when run-time no longer meets your needs.

What limits continuous use of the 11.1V 3700mAh cell — thermal throttling, voltage sag, or firmware cut-off?

Under sustained load the pack will hit its firmware voltage cut-off first, ending the session to protect the cells.

How much heat or fan noise does the DB5D replacement generate when the EliteBook Folio 1040 runs all day on battery?

The battery itself produces minimal heat and no noise; any warmth or fan activity comes from the laptop’s own components.
