Replacement battery for HP G4 series

This lithium-ion battery replaces original HP part numbers 807956-001, 807957-001, HS03 and HS04. It fits HP 240 G4, 245 G4, 246 G4, 250 G4, 255 G4 and 256 G4 notebooks. The unit is new from the manufacturer and rated for up to 500 recharge cycles over its lifespan.

Upgrade from a depleted or swollen original

The jump is worth it when the factory pack no longer holds a charge, runs hot or shows physical swelling. It also restores mobility for machines still used daily on battery power. Buyers who need higher capacity than the standard cell count cannot be served by this direct replacement.

Straightforward swap with basic precautions

Installation requires removing the bottom case screws, disconnecting the old pack and connecting the new one in the same orientation. Common issues include forgetting to disable the internal battery in BIOS before starting, stripping small case screws or pinching the ribbon cable during reassembly.

Questions about this item

Will the HS03 HS04 battery fit my HP 250 G4 without any chassis modifications?

Yes, the battery is built to match the original HS03 and HS04 form factor used in the HP 240 G4, 245 G4, 246 G4, 250 G4, 255 G4 and 256 G4 series, so it slides into the existing bay without modification.

What is the correct order to install the replacement battery so the laptop recognises it immediately?

Power off the notebook, disconnect the AC adapter, remove the old pack, insert the new HS03 HS04 unit until the latch clicks, reconnect the adapter and let it charge to 100 percent before first use.

After roughly how many charge cycles should I plan to replace this lithium-ion pack?

The manufacturer rates the cell for up to 500 recharge cycles over its lifespan; after that capacity will drop noticeably and a fresh battery will be needed.
