Only a few people ever seen “Bigfoot”. “Littlefeet” is not that shy. The Sony Energytec 17670, measured 2.2 volts after not being use for many years. The Panasonic 17670 came in kicking with 3.9 volts. These batteries was a rare find for me but no matter what the size or how old I put them to work immediately.
