Wanna check whether my new battery is Genuine or not?

Hi Priyank,

Thank you for writing to the Dell Community Forum.

The part number from the battery tells that it is a genuine Dell battery. It is a 48Whr, 6 Cell battery. 

Battery backup depends on the environment and usage of the computer.

Here are the few factors which may affect battery performance:

• Processor speed - Enabling features such as Intel Speed Step or AMD Power Now! Extends battery life by automatically adjusting the processor speed to meet system demands. These features are typically enabled by default on computers that support them.

• CD, DVD, CD-RW and hard drive access frequency - Moving files and programs directly to the hard drive, when possible, reduces the number of devices requiring battery power. Adding more memory can also help by reducing the need to use a swap file on the hard drive.

• Programs - Running only the programs that are necessary reduces demands on the system processor and memory. Programs that cause intensive use of the processor and drives (such as playing a DVD movie or 3D games) can more than halve the amount of time that the computer can be used on battery power.

• LCD brightness - Lowering the brightness of the LCD screen reduces the amount of power required by the screen. To adjust the brightness of the LCD screen, press + to increase the brightness or + to decrease the brightness on the LCD display panel.

• Backlit keyboard - Turning off or halfing the brightness of your backlit keyboard can conserve battery power for when you are using your computer. Typically to adjust the brightness of the backlit keyboard, press + to cycle through two brightness settings and the offsetting.

• Power management - Set the computer to enter suspend or hibernate when idle to conserve battery power when the computer is not being used.

• Battery age - A battery's average life expectancy is 1 year. After this time, it is normal to experience a decrease in battery life.

• Battery age/life is in no way shortened, when the portable computer is directly connected to AC Power (power outlet) and continuously used for long period of time. The reason is that the system motherboard automatically stops power flow to battery, as soon the battery is fully charged.

I recommend to update BIOS from the below mentioned link:
