How do I connect a lead acid battery?

There are three ways to connect your lead acid batteries—parallel, series, and a combination known as series/parallel. We cover each of these battery configurations in greater detail in our Battery Basics tutorial section of the site should you want to delve in a little deeper or reinforce what you already know.

How to connect batteries in parallel?

Connecting batteries in Parallel is normally performed to increases capacity. This can be done by connecting the positive terminal of the first battery to the positive terminal of the second battery. Likewise, the negative terminal of the first battery is connected to the negative terminal of the second battery.

Should a lead acid battery be positive or negative?

Safety Rule #2 -- When Installing a Battery Start with the Positive There is a serious amount of stored potential energy available in a sealed lead acid battery. A shorted car battery, for example, can deliver several hundred amps in the blink of an eye. To put that in perspective that is more than an arc-welding machine.

How to connect a battery in series?

Connecting batteries in series means to connect the positive terminal of the first battery to the negative terminal of the second battery and so on down the string. The interconnecting cables must have equal lengths and resistance to equalize of the load.

Can a 12V battery be connected in series?

When creating a lead-acid battery bank with a higher voltage, like 24 or 48V you will need to connect multiple 12V batteries in series. But there is one problem with connecting batteries in series, and this is that batteries are not electrically identical. They have slight differences in internal resistance.

Why are batteries interconnected?

Batteries are interconnected to increase the battery voltage or to increase the battery capacity or both. Multiple interconnected batteries are called a battery bank. When batteries are connected in series, the voltage increases. When batteries are connected in parallel, the capacity increases.
