I have run the battery in a wireless doorbell. the first held about half a year, which is not particularly long is now in view of the fact that the bell at home rarely used. but for the transmitter hanging outside in the winter, that's still ok. as I then used the second battery, unfortunately, there was no reaction to the bell. Voltmeter out and lo and behold. 11.2 V under load. shame because on the package was stable until 2017th
