Replacement battery for HP business laptops

This 6-cell lithium-ion pack restores mobility to compatible HP EliteBook and ProBook models including the 8440P, 6550B, 6930P, 6440B, 6450B, 6735B and 6545B. It suits professionals and students who need a reliable power source for daily work away from a desk. Buyers whose laptop uses a different form factor or voltage should look elsewhere.

Thermal behaviour and power draw

The battery operates at 10.8 volts with a rated capacity of 4400 mAh and 48 Wh, delivering consistent energy without active cooling. Built-in protection circuits guard against short circuit, overheat and overload during normal charging and discharging cycles. Grade A cells are tested to provide up to 500 charge cycles while maintaining stable output.

Fit and system impact

The pack fits directly into the existing battery bay of the listed HP models and uses the original latch mechanism, requiring no tools or adapter cables. Its 6-cell design keeps the laptop profile unchanged and leaves all ports, drives and expansion slots free. The 12-month warranty covers defects in materials and workmanship.
