PostSubject: What is the run time of HP Compaq laptop battery   Mon Nov 07, 2011 3:16 pm






HP Compaq Notebook Battery have two main ratings on them: Volts and Amperes. Because size and weight of it is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Mill amperes. One thousand Mill amperes equals 1 Ampere. When buying a battery, select batteries with the most Mill amperes (or Ah). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all.This is found by multiplying the Volts and the Amperes together.For example: 14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).14.4 x 4.0 = 57.60 Watt-Hours Watt-Hours signifies the energy needed to power one watt for one hour. This HP Compaq Laptop Battery can power 57.60 watts for one hour. If your laptop runs at 20.50 watts, as an example,this Battery could power your laptop for 2.8 hours. 133 Watt External Laptop Battery Charger Runtime Up to 10Hrs Upgrade my HP Compaq Laptop Battery from Ni-MH to Li-ionNi-Cd, Ni-MH and Li-ion HP Compaq Notebook Battery http://www.lapbattery.com/ are all fundamentally different from one another and cannot be substituted unless the notebook has been pre-configured from the manufacturer to accept more than one type of battery chemistry. Please refer to your manual to find out which rechargeable battery types the laptop device supports or use our HP Compaq Notebook Battery Finder above to find all the compatible Laptop Battery for your device. It will automatically list all of the battery chemistries supported by your specific device. If your device does allow you to upgrade the battery from Ni-MH to Li-ion, you will typically get longer run times. For example, if your laptop uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion laptop battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the Li-ion battery.Example.Li-ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt HoursNi-MH: 9.6 Volts x 4 Amperes = 38.4 Watt HoursThe Li-ion is stronger and has longer run time.Any question please feel free to contact with me.http://www.lapbattery.com/
