Replacement battery for HP Omen 15

The POWER-FENG RR04 is a 15.2V 58Wh lithium-polymer battery built for HP Omen 15 models including the 15-5014TX and TPN-W111 chassis. It replaces original part numbers RR04, HSTNN-LB6N, 778951-421 and 778978-005. The unit is brand new and intended for owners who need a direct swap without adapter changes.

Thermals and power draw in daily use

The 3720mAh cell delivers steady 15.2V output for typical office work, web browsing and media playback. Lithium-polymer chemistry keeps self-discharge low during standby and the black casing matches the original aesthetic. No active cooling is required because the battery runs passively inside the laptop chassis.

Behaviour under sustained load

During extended gaming or rendering sessions the pack maintains voltage until the controller initiates a controlled shutdown at the firmware threshold. It is not designed for users who need hot-swap capability or a secondary battery bay. Capacity will follow the standard lithium-polymer ageing curve over repeated full cycles.

Questions about this item

How do I install the 58Wh RR04 battery in my HP Omen 15 and what step do people often miss?

Remove the bottom cover, disconnect the old battery cable, fit the new 15.2V Li-polymer unit, and reconnect the cable before refitting the cover; the step often missed is disconnecting the cable first.

What maintenance or replacement will the 58Wh RR04 battery need over time?

Li-polymer cells degrade with charge cycles; expect reduced runtime after several hundred cycles and plan to replace the 3720mAh pack when it no longer holds a useful charge.

What limit appears first when the 58Wh RR04 battery runs under sustained load?

The 15.2V output will sag as the 58Wh capacity depletes, so runtime is the first limit you hit during continuous use.
