It's a Dell part number, but there is no way to know if it's original to the system.  If it is, bear in mind that system is about four years old, so the battery is likely at or near the end of its expected lifespan.  In fact if it is original, and the battery still works - that's quite a good thing, since they generally last 2-3 years.

It looks like that battery was made in April 2016, so it's about six months old.

Hi KARTHICKG24,

Where have you purchased the battery from? 

If purchased from a 3rd party seller, there is no way to ascertain if the battery is new or refurbished. You could however, check if the battery health in BIOS - press f2 on startup - and also by determining the battery durability after a full charge. This should paint a picture of the current battery life.

Let us know if you have any other queries.

Thanks ejn63, Dell Rishi for a response.

Bought battery Amazon. from a seller.

I checked with BIOS - It Says "The Battery is functioning normally"

Durability.

It shows 3 - hours battery remaining for 80% in idle state (Without Wifi)

It shows 1 hours battery remaining for 60% with Wifi and Google Chrome(Full brightness

It varies rapidly in battery indicator

can you tell this is normal behaviour for original battery

It depends on the system configuration and on how you have the power management set - screen brightness, resolution and the GPU in the system.

If it's an i7 with a discrete GPU, you may see as little as an hour or two runtime from a new battery.  If it's a less power-hungry configuration, such as an i3 with integrated video, you may get 2-3 hours from it, but this is not a highly power-efficient system.

Hi KARTHICKG24,

Thank you for the update.

You could also maximize the battery health -> go to BIOS -> f2 on startup -> Advanced battery charge configuration -> enable advanced battery charge mode.

Let us know if you have any other queries.
