Certified to CE, FCC and UL standards, it is built for users who need a dependable drop-in replacement.

Fits multiple HP and Compaq models

The battery matches a long list of compatible part numbers including 462889-121, 462890-542, 482186-003, 484171-001, 485041-001, 487296-001 and 487354-001.

Thermals, noise and power draw

As a solid-state chemical cell the unit produces no fan noise and adds no active heat beyond normal discharge warmth. Fast-charging support lets it replenish quickly from the laptop’s stock adapter, while the rated 1000 recharge cycles indicate a long service life. In daily use it simply supplies power until the system signals low charge.
