Offered is a nice clean pair of MAXELL 9-Volt Batteries from the 1960's. The batteries are very clean and both appear unused. They are very similar, but one is by Maxell Electric and the other is by Nitto Electric. Both batteries bear pat. no. 228142 and part no. 006P-9V.  The Nitto Electric battery has some crazing on one side, otherwise, it is very nice. The Maxell Electric battery is in excellent condition. DMM voltage measurements are as follows:  218mV and 290mV. Pick up the vintage seldom-offered 9-Volt batteries for your own collection. MAXELL Dry Battery for Transistor Radios. The Maxell and Nitto logos are nearly identical-visible in photos. Mouse over the photo images to zoom in.  NO RESERVE!! Thanks for looking.
