Battery holder drop voltages?
Recently my wireless mouse stop working, so I open it to inspect around, and I found out that at the connecting terminal between the battery holder and the mouse PCB, the voltage is only 1V (unplugged from the mouse itself) , but when I take the battery out to measure, each of the battery got 1.5V. And when I measure on the 2 metal ends (of the holder), my multimeter read 1.7V. So, what's wrong with it? Can anyone help me with this? It's really the first time I have a situation like this
