Do battery cables need to be the same length?

Choosing the correct size (diameter) and length of cable is important for overall efficiency. Cables that are too small or unnecessarily long will result in power loss and increased resistance. When connecting batteries in series, parallel or series/parallel the cables between each battery should be of equal length.

Does revving the engine charge the battery?

The battery will charge faster if you rev the engine faster. Why? Because the faster the crankshaft turns, the faster it turns the belt that runs the alternator. And the faster the alternator turns, the more electricity it produces to run all the electrical stuff in the car — and recharge the battery.

Two or more 12-volt batteries wired in series—the positive terminal of one battery connected to the negative terminal of a second battery—develops 24 volts, but amperage doesn’t change.

How do you connect batteries in parallel to extend runtime?

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.

Can positive and negative wires be different lengths?

Most of the time, it doesn’t really matter for a DC circuit. If one wire is excessively long, its resistance may become a problem. If your circuit is susceptible to electromagnetic interference, then using short wires, run close to each other, may help. In other cases, it makes no difference at all.
