Replacement battery for HP ProBook

This 6-cell lithium-ion pack replaces original HP part numbers 718754-001, 718755-001, 718756-001 and 718757-001. It fits ProBook 640, 645, 650 and 655 series models including G0 and G1 revisions. The unit delivers 10.8V and 4400mAh for 48Wh of capacity.

Thermals noise and power draw

The internal smart control chip manages charging current to reduce heat during normal operation. Built-in protections guard against short circuit, overheat and overload conditions. Lower power consumption during charge cycles helps keep the laptop running cooler. No moving parts mean silent operation at all times.

Sustained load behaviour

The 6-cell design supports extended discharge time for long work sessions away from mains power. Cell chemistry maintains stable voltage output under continuous load without sudden drops. The 1-year warranty covers capacity retention under regular daily cycling. Buyers who need higher capacity than 4400mAh should verify alternative options.

Questions about this item

How do I install the MPL08273P-02 battery in my HP ProBook 650 G1, and what step is often missed?

Power off the laptop, unplug the AC adapter, slide the release latch to remove the old pack, insert the new 6-cell unit until it clicks, then charge it fully before first use; the step often missed is that initial full charge.

What maintenance or replacement will this 4400 mAh lithium-ion pack need later?

The 6-cell lithium-ion battery will gradually lose capacity over hundreds of charge cycles; plan to replace it when run-time drops below your needs, typically after one to two years of daily use.

What limit appears first during sustained use of this 10.8 V 48 Wh battery?

Under continuous load the pack will hit its 4400 mAh capacity limit first, after which the smart control chip triggers overload protection and shuts down output until recharged.
