40Wh 14.6V Li-ion replacement for HP Pavilion

This 40 watt-hour lithium-ion battery operates at 14.6 volts and delivers 2800mAh capacity. It fits HP Pavilion 14, 15 and 17 series notebooks including 15-ac, 15-af, 15-ay, 15-ba, 14-ac, 14-af and 17-x models. The pack replaces original part numbers HS03, HS04, 807956-001 and HSTNN-LB6U among others. It is built new and carries CE, FCC and RoHS certifications.

Voltage matching is the only hard limit

The cell chemistry requires a 14.6V nominal input; 14.4V and 14.8V original batteries are also compatible. Versions rated at 11.1V or 10.85V will not work and must be avoided. No other electrical or mechanical constraints are specified by the supplier. Protection circuits guard against short circuit, overcharge, over-discharge and over-voltage conditions.

Upgrades 2200mAh originals in supported chassis

Users replacing a 2200mAh pack gain a measurable capacity increase without changing form factor. The improvement applies only to laptops listed in the compatibility table that originally shipped with a 14.4V, 14.6V or 14.8V battery. Owners of 11.1V or 10.85V systems cannot use this unit and should seek the correct voltage variant instead.

Questions about this item

How do I know whether the 40Wh 14.6V HS03 is the correct version for my HP Pavilion?

Match the original battery voltage — this unit is 14.6V and also works with 14.4V or 14.8V originals, but it will not fit 11.1V or 10.85V versions.

What runtime can I expect from the 40Wh 2800mAh capacity in daily use?

The 40Wh rating means the pack can deliver 40 watts for one hour; actual runtime varies with screen brightness, CPU load and Wi-Fi use, but it is higher than the older 2200mAh packs.

Does the HS03 use a standard HP connector that fits the Pavilion 15-ac and 15-af chassis?

Yes — the replacement is built to the HS03/HS04 form factor and matches part numbers such as 807956-001, HSTNN-LB6U and N2L85AA used across those series.
