MacBook Pro 15 inch 2010 battery replacemet

Hi,

I would like to know if there is any other way i could buy a macbook pro 15 inch 2010 battery. My Mac battery has been removed as it had buldged and not working anymore. Last I visited to store and told Apple pushed this to vintage model and no longer service is available.

Could someone help me finding the battery for my Mac, Is there anyway I could get the original battery or compatible. If its a compatible how long will be the life for this.

Thanks in advance.
