Replacement battery for Pro Tablet x2 612 G2

This 41.58Wh lithium-ion pack replaces the original SE04XL cell in HP Pro Tablet x2 612 G2 devices. It matches the 7.7V specification and fits the full range of listed part numbers including HSTNN-DB7Q and 21CP4/65/81-2. The black finish matches the factory appearance.

41.58Wh capacity and 7.7V output

Rated at 41.58Wh, the battery restores the tablet’s original runtime for typical office workloads and mobile use. Capacity drops under sustained heavy loads or when the cell ages, so very long sessions away from power may need a spare or external charger.

The unit replaces part numbers SE04XL, 860708-855, 860724-2B1, 860724-2C1, HSTNN-DB7Q and 21CP4/65/81-2 without modification. It is not for tablets outside the Pro Tablet x2 612 G2 series or for users needing a higher-watt-hour alternative.

The package contains the SE04XL lithium-ion battery only; no tools, screws or cables are included, and none are required for the Pro Tablet x2 612 G2.
