Thinking of going to 6v batteries

How tall are the 6v batteries from lowest point to highest point? I need to know if they will fit in my battery compartment.

I took a cutting torch to my compartment to fit 6 V batteries. I lowered the compartment base 2". It was worth it. While I was in there, I moved a steel support for a step and that gave me room for 4x6 volts instead of two. I also found a hidden area that I opened up and added a hinge to, and suddenly had another tiny compartment under the step for free!
