# Question: How do you connect 3 12-volt batteries together?

Contents

To join batteries in parallel, use a jumper wire to connect both the positive terminals, and another jumper wire to connect both the negative terminals of both batteries to each other. Negative to negative and positive to positive. You CAN connect your load to ONE of the batteries, and it will drain both equally.

## Will batteries in parallel last longer?

In a parallel circuit every load receives the same voltage. When batteries are hooked up in parallel, the voltage remains the same, but the power (or available current) is increased. This means that the batteries would last longer.
