Use spare internal battery as external power bank?

Hello! I purchased a replacement battery for my old laptop right before it all-together died, so i’m stuck with a useless $100 battery. Does anyone know if someone makes a connector/adaptor to convert it to a portable power bank that I could use with my new laptop? The battery is the one sold by iFixit for the early 2011 15” MBP (unibody), part #IF161-107-1.
