Can a lead acid battery be connected in parallel?

In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.

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.

Can a lead acid battery be voltage charged?

Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage.

Why do I need a parallel battery configuration?

Connecting batteries that are different can lead to trouble. The goal of parallel battery configurations is to increase your systems overall capacity. This is used when you want your application to run longer between charging. The voltage will not increase using this connection method.

Do you need a fuse for a lead acid battery?

In actual practice, people put lead acid batteries in parallel and cycle them that way frequently. Just look at RV's and boats and off-grid installations. A fuse for each battery would not be a bad idea. If you are charging them all anyway then what does it matter if one discharges into another?
