Replacement battery for HP ProBook series

This 6-cell lithium-ion pack replaces the original battery in compatible HP ProBook, EliteBook and Compaq models including the 6440b, 6450b, 6545b, 6550b, 6730b and 8440p. It delivers 10.8V and 4400mAh capacity to restore mobile runtime for professionals who rely on these laptops daily.

Thermal and power behaviour in use

The lithium-ion chemistry operates at the rated 10.8V without generating excessive heat during normal charging and discharging cycles. A built-in smart control chip manages power flow to reduce consumption and extend discharge time while protecting against short circuit, overheat and overload conditions.

Fit and system integration

The pack fits directly into the existing battery bay of the listed notebooks, requiring no adapter or cable changes. It frees the user from tethered outlet dependency and restores full portability for travel or meeting-room work where mains power is unavailable.

Questions about this item

How do I install this 6-cell 10.8V battery in my ProBook 6545b, and which step do people often miss?

Slide the pack into the battery bay until both latches click, then let the smart chip calibrate through one full charge cycle before relying on the gauge.

What maintenance will this 4400mAh lithium-ion pack need over its life?

Run a full discharge and recharge every 30 to 40 cycles to keep the built-in gauge accurate; no other user service is required.

What limit appears first when I push this 48Wh battery hard for long periods?

The overheat protection trips before the overload or short-circuit limits, throttling output until the cells cool.
