Replacement Battery for HP 11.4V Systems

This 11.4 V lithium-ion pack delivers 46 Wh across three premium cells and matches part numbers HSTNN-I66C-5H, HSTNN-I67C-4, HSTNN-I67C-5, 801517-221 and 801517-222. It is built for HP laptop owners who need a direct, CE- and RoHS-certified replacement that restores original run-time without modification.

Upgrading from a Depleted Original Pack

The battery replaces an aged or failing factory unit that no longer holds a useful charge, eliminating sudden shutdowns and short unplugged sessions. The jump is worth it when the original cell chemistry has degraded below 100 % health and the laptop cannot complete a typical work period on battery power alone.

Sustained Output Under Continuous Load

Premium lithium-ion cells maintain stable voltage through extended discharge cycles, so the laptop runs at full speed during long meetings, media playback or compile jobs without throttling caused by voltage sag. Rigorous testing targets consistent capacity retention over many charge cycles, reducing the frequency of future replacements.
