For sale is a battery harness adapter for vintage 9 volt round and cube batteries. This will adapt a modern, rectangular 9 volt battery to be compatible with the larger snap clips found on round and cube 9 volts of the past. Compatible with 9 VOLT systems only.
I fell down the rabbit hole fixing up old geiger counters from the 50's. As you are reading this, you know all to well the availability of functioning batteries is problematic for vintage electronics. Modern remakes are exceedingly expensive and likely have been on a shelf for some time and have lost some of the power. This harness allows you to use inexpensive modern batteries, so you can actually use and enjoy your device.
Other sizes and styles of batteries are in the works,412-22.5volt, 455-45volt, 467-67.5volt and possibly others as I find devices that need power. This sale is for the 9 volt, modern to round or cube harness only.
The batteries in the second and last photo are for reference only and not included in the sale, nor are the
412-22.5volt, 455-45volt, 467-67.5volt batteries.
Please ask any question before purchase.
