Replacement battery for HP Pavilion 15 series

This 14.6V lithium-ion pack replaces worn original batteries in HP Pavilion 15-ac, 15-af, 15-ay and 15-ba models. It delivers 38Wh capacity across four cells and matches OEM specifications for stable daily runtime. The unit is brand new and ready for immediate installation.

Thermals noise and power draw in normal use

Built-in protection circuits guard against overcharge, overvoltage, overcurrent, short-circuit and overtemperature events during charging and discharge. The battery operates at 14.6V, compatible with 14.4V and 14.8V labels, and draws power within the limits of the original laptop charging system. No active cooling or fan noise is involved.

Upgrade from depleted original packs

This battery replaces part numbers HS03, HS04, 807956-001, 807957-001, TPN-W121, TPN-L119, HSTNN-LB6U, HSTNN-LB6V, HSTNN-DB7J and several 807611 and 807612 variants. The jump is worth it when the original pack no longer holds sufficient charge for mobile use. It is not suitable for 11.1V or 10.85V systems even if the physical shape appears identical.

Questions about this item

How do I install the HS04 battery and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the bottom case screws, unplug the old battery connector, fit the new 14.6V 38Wh pack, reconnect the cable, replace the case and screws, then charge fully before first use.

What maintenance or replacement will the 4-cell Li-ion pack need later?

The 2600mAh cells degrade over time; expect reduced runtime after several hundred charge cycles and plan to replace the pack when it no longer holds enough charge for your workload.

What limit appears first during sustained use of this 14.6V battery?

The built-in protection IC will cut power if the pack overheats, hits overcurrent or overvoltage thresholds, so thermal limits trigger before the 38Wh capacity is fully drained.
