Positive and negative electrode identification of button battery holder
Usually button batteries have a “+” mark for the positive terminal, the back is a negative terminal.
Button battery shell edge is positive, so most of the button battery holder load button batteries are the positive upward, because the button battery holder metal shrapnel stuck button battery in the side to prevent out, this is the positive electrode metal shrapnel, shrapnel will cling to the positive edge button battery, due to the positive electrode metal shrapnel large-area electrode contact, Effectively improve the stability of electrode contact; If the button battery positive and negative switch, can also jam the battery, but the battery short circuit.
