This NiCad battery pack is for a very old AV-7600 portable transceiver. It was special order when I decided to get a replacement (I was using Lithium AA cells in 2 spare battery packs that I had that came with the unit 25 years ago). It took a few months to get it, but it works great & I’m pleased it’s still available. I tried repairing the original, but that proved difficult. Not really repairable. A replacement set of batteries is available, but at Spruce price it only saves $10 & good luck trying to open the case to solder them in.
