How Do You Connect 9V Batteries In A Series?
Connecting a battery in series doubles the voltage output while keeping the same capacity rating as one battery. In the case of a 9V battery, this means the output of two batteries connected in series will be 18V. This can be useful for devices that do not run on a voltage that equates directly to a standard battery size, and for devices that need more power at a rate similar to a smaller battery. Connecting in series does not have to end at two batteries, and you could potentially chain together as many batteries as you needed in this way. To make a series connection between two 9V batteries you only need a few 9V battery clips. Connect the positive terminal to the positive 9V clip of the device you wish to power, but leave the negative terminal disconnected. Take a second battery clip and jump the connections running from the positive and negative clips by twisting the ends of the lead wires. This will allow this clip to act as a bridge between two separate batteries. Connect the neg
