Six cell lithium ion 10.8V 4400mAh 48Wh pack
The battery uses six lithium ion cells rated at 10.8 volts and 4400 milliampere hours, delivering 48 watt hours of energy. A built in smart control chip manages charging and discharging while providing short circuit, overheat and overload protection. Runtime depends on the laptop power draw and workload; this capacity may not sustain high performance configurations for long periods. It is not for systems that require a higher watt hour rating or a different voltage.
Voltage and capacity must match original exactly
The single specification that decides fit is the 10.8V 4400mAh rating matching the original HP battery. If the original part shows a different voltage or capacity this unit will not work correctly. Verify the part number on the old battery against the list above before purchase. It is not for buyers who cannot confirm their original battery specifications.
