I have a portable radio that uses 4 C" cells. Volume was getting low so I checked the voltage across all 4 batteries, it was 2.8V. Then I checked across 2 batteries and got 0.34V. Seemed odd, I checked across 1 battery and got 1.3v I checked the other and got 1.1v. Ya, I checked across both again! 0.34v. I pulled the 2 batteries out, one of them is 1.1v reverse direction. I have not seen this before, alkaline batteries. No charging involved. Anyone seen this before. Mikek
PS. I don't usually use alkalines, so maybe this happens, I just never saw it.
