HP Battery 3C 51Wh 4.68Ah LI (M64307-171)

This HP battery replaces the original power source in select Pavilion and Envy x360 laptops, restoring full runtime with a 51 Wh lithium-ion pack. Unlike generic replacements, it matches the exact electrical profile of the original 3-cell unit, so the laptop charges and reports remaining capacity correctly.

Highlights

• 51 Wh energy capacity keeps compatible notebooks running through a full work session.
• 3-cell lithium-ion design with 4.68 Ah charge for stable voltage delivery.
• 11.55 V nominal voltage aligns with HP's power management circuitry.
• Black housing matches the laptop's internal colour scheme.

In daily use

Installation is internal, as with the original battery. The pack fits HP Pavilion 15-eg, 15-eh, 14-dv, 14-eh series and HP Envy x360 15-eu, 15-es series, among others. Once seated, the system recognises the battery and resumes normal charge/discharge cycles without driver changes.
