Dell HS04 14.6 V 38 Wh battery for HP Pavilion 15

This four-cell lithium-ion pack delivers 14.6 volts and 38 watt-hours of capacity. It replaces the original HP 807956-001 HS03 unit in compatible Pavilion 15-AC, 15-AF, 15-AY and 15-BA models. The battery fits HP 240 G4 through 256 G4 series notebooks as well. Buyers who need an 11.1 V version cannot use this pack.

Sustained output with built-in protection circuits

An intelligent power-management IC guards against overcharge, overvoltage, overcurrent, short-circuit and overtemperature conditions during long work sessions. The 2600 mAh rating supports steady discharge without sudden voltage drops. Cells maintain stable output while the protection logic monitors each parameter continuously. Users who require hot-swap capability will not find it here.

Direct fit replacement with voltage verification

Installation follows the standard battery-bay latch mechanism used across the listed Pavilion and G4 chassis. No tools are required beyond releasing the locking slider. The critical step is confirming the original battery shows 14.6 V (or 14.4 V/14.8 V) on its label before ordering. Buyers who skip this check often receive a pack that physically fits but will not charge.
