This 9v battery contained six cells stacked like a layer cake

Picture of a disassembled Duracell 9v battery. Below the terminal assembly is a clear plastic case where you can see six sets of stacked rectangular terminals and fillings.
About a decade ago I told my spouse I wanted to customise my PC with a perspex case and some lighting inside. He was all bleurgh, why would you want to do that?! His current PC has a glass side and rainbow lights inside.
I also stand by this claim and have since the 90s. Thank you and good day, sir.
Congratulations! We are increasing our numbers!
