Notebook Battery Replacement?

[directorjewels]

My laptop has been repeatedly shutting itself off with no indication the battery is low. Upon restart, it displays an error message that the internal battery may need to be replaced. 

Is this the regular battery replacement part that I can purchase from the parts store, or something else? 

Thanks for any help.
