A Replacement for Impossible to Find Mercury Batteries
I bought this product to power an old, but still very useful photographer's light meter.  It used a mercury battery that is no longer made because of the environmental damage waste mercury can cause.<br /><br />This battery is a close match to the outline of the PX13 battery I needed to replace.  It's either not perfect, or my meter's battery compartment has gotten flexed too much - the new battery isn't quite as tall as the compartment needs it to be.  I had to (gently!) tweak on the contacts to make it work, which it now does.<br /><br />This battery is a good choice to power old devices.  However, if fit is a problem, I might suggest looking into other options.
