Knowledge about watt-hours, volts and milliamp-hours of laptop battery

Many people may feel confused when comes to the watt-hours, volts and milliamp-hours in your laptop battery.Today we will tell you what are watt-hours, volts and milliamp-hours and take some examples to let you better understand.

watt-hours, volts and milliamp-hours are 3 ratings that each laptop battery has.

Watt Hours (wHr): is a unit of energy equal to the work done by one watt acting for one hour and equivalent to 3,600 joules. The wHr is a calculation of voltage and mAh. 

Milliamperes (mAh):  is a unit of measure electric power over time. It represents the total amount of energy store in your battery. The mAh rating is also a measure of the number of hours a battery may last. The higher a battery's amp hour rating is, the longer the battery's run-time will be. It is not uncommon for some of our batteries to have higher or lower amp ratings. This will not cause any incompatibilities.

Voltage (V): is the amount of electricity that is delivered to your computer. The amount of energy from your wall outlet is greater than what your laptop needs to operate. Therefore a power adapter contains a box like bar that will decrease the energy lowering the voltage rating. Each computer manufacturer designs their computers for the appropriate voltage requirement. Your battery pack will then be engineered to match the voltage of the power AC adapter. Laptop battery packs are composed of several battery cells that are wired together in series. While the voltage of the Hi-Capacity battery may not be identical to the original battery, the voltages must be within a reasonable range. Any replacement laptop battery should always be within +/- 1V. Anything above that range may cause incompatibilities.

Examples:

CLEVO P375SM Laptop Battery, P375SM batteries

 

 The capacity of CLEVO P375SM Laptop Battery is 5900 Milliamperes (mAh ),  which means

CLEVO P375SM Laptop Battery can store 5900 energy when fully charged.

The voltage of CLEVO P375SM Laptop Battery is 15.12V, which means
CLEVO P375SM Laptop Battery can deliver 15.12 electricityto your laptop.

The wHr ofCLEVO P375SM Laptop Battery is 89.21W, which is the a calculation of voltage and mAh of CLEVO P375SM Laptop Battery

LG SQU-1007 Laptop Battery, SQU-1007 batteries

 The capacity of LG SQU-1007 Laptop Battery is 4400mAh,which means LG SQU-1007 Laptop Battery can store 5900 energy when fully charged.

The voltage of LG SQU-1007 Laptop Battery is 11.1 V, which means LG SQU-1007 Laptop Battery  can deliver 11.1 electricityto your laptop.

The wHr of LG SQU-1007 Laptop Battery 49W, which is the a calculation of voltage and mAh of

LG SQU-1007 Laptop Battery .

Note: 

•  Higher capacity laptop batteries can work longer than the lower capacity ones, but they are bigger and  heavier accordingly.

• Capacity will not cause incompatibility problem.
