I have 2 batteries in a double-get, both of which were completely empty. Supposedly by 2016 usable, actually worked the first battery for about 3 days, and the second I then measured only. She was completely empty. Comment of consignor: Either the device is defective and has damaged both batteries (even though I had only one used) or I made a mistake at the onset, which led to short-circuit. (Probably both at the same time or whatever - must logically such comments yes not necessarily, but only useful for the sender) What is odd is that the clock suddenly working again with a local (more expensive, of course) acquired battery. I guess yes, the clock has given the new battery easily repaired itself.
