Do these? The answer is yes and no! yes if you just put this in any equipment right away. No if you first check the voltage, if too high then just put a small 4 volt DC light to it for a minute or so, then check the voltage again with a dc voltage meeter. If the 2032 battery voltage is around 0.1 - 0.2 dc volts from 3.6v then it wont hurt nothing.
