Replacement Battery for EliteBook Folio G1

This 38Wh lithium-polymer pack is built for the HP EliteBook Folio G1 series. It matches the original 7.7V specification and 4935mAh capacity so the notebook runs for the same length of time on a full charge. The black finish matches the chassis colour. Buyers who need a higher-capacity cell or a different voltage should look elsewhere.

Direct Fit for Part Numbers EO04XL and HSTNN-IB7I

The cell replaces OEM part numbers EO04XL, HSTNN-IB7I, 827927-1B1 and 828226-005 without adapters or cable changes. No extra software, drivers or calibration utilities are bundled in the package. The laptop’s own firmware handles charge management exactly as it did with the factory battery.

Simple Internal Swap with Common Screws

Installation requires opening the bottom case and disconnecting the old pack, usually with a small Phillips screwdriver. The connector keying prevents reversed insertion. The most frequent issue is forgetting to detach the internal cable before lifting the motherboard, which can strain the socket.

Questions about this item

How long will the 38Wh Li-polymer cells last before they need replacement?

Li-polymer cells in this 38Wh pack are rated for typical cycle life; expect service life to vary with charge depth and temperature.

What limits runtime first when the EliteBook Folio G1 runs a sustained load on this 7.7V battery?

The 4935mAh capacity at 7.7V sets the energy ceiling, so runtime under heavy draw is bounded by the 38Wh rating.

How much heat does the EO04XL produce when the laptop runs all day on battery?

Internal resistance in the Li-polymer cells generates modest heat during continuous discharge; the pack has no active cooling.
