How to Choose the Right Battery Connectors

When it comes to achieving a higher level of efficiency, having the right battery connector can go a long way. You will find these components in a variety of settings, generally “modular” connectors that can be tailored to meet certain specifications.

All of this leads to one conclusion: choosing the right battery connector. Choosing incorrectly can hinder performance and ultimately bring entire systems to a halt. For industrial settings, that can wind up being quite costly to the bottom line.

Current Capability

Before you go looking for battery connectors from a quality vendor like RS, there are a few specs that you should be keeping under consideration. For starters, each battery connector you find will have a rating that tells you just how much current it is capable of withstanding. This is vital for safety reasons and for preventing damage to the connector.

Given the various technological advancements in the industrial sector, having the right battery connector can pay dividends. Check current capacity as well as voltage rating (more below) in order to find out what size, as well as the spacing and number of contacts required. This will impact the material and design of the connector that you end up going with.



When choosing a component of any kind, durability is going to be one of the most critical factors. After all, you don’t want to have to endure the installation process any sooner than necessary. When it comes to choosing the right battery connector for your given application, durability is going to be near the top of the list when it comes to determining factors.

That said, outside factors can play a part in the overall durability of the battery connector that you choose. Life span, material, and the conditions it is exposed to can all cut the usage of a battery connector short. Keep in mind what external conditions will be at play when making your choice. After all, using a battery connector that isn’t meant for a particular usage will ultimately result in greater corrosion and the need to replace the connector before long. Save yourself the time, money, and frustration by checking out the durability ratings on the battery connector first.

Voltage Capability

Another major factor in choosing a battery connector is knowing what the maximum operating voltage is. Choosing the wrong connector means potentially exceeding the voltage limit, which can be dangerous for both the connector and the technician. Make sure that you have the right connector is used with the proper required voltage.

The good news is that battery connectors come with different color coding to make choosing the right connector easy. Make sure that you are only using like-for-like colors to avoid the potential misconnection of components. They can even be rotated 180 degrees so that similar parts are able to be plugged into one another.

Termination Type

Terminations are what bring the connectors together to their respective conductors. Terminations can also be achieved in a few different ways depending on the terminal type. Those include soldered, press-fit, wire-wrap, and crimped connections, with the latter being the most commonly used connection.

Crimping is gas-tight, preventing moisture and oxygen from getting in to make contact with the metals. They are also mechanically stronger than the soldered connections, plus they use no alloy. That’s not even mentioning the multi-purpose use of crimped connections, perfect for both small and large cross-sections whereas wire wrap is only good for small cross-sections. Finally, installing crimped connections is less time-consuming and ultimately safer than the others.
