Battery Contacts: Their Construction and Different Types

A battery contact is something that helps you to connect the battery to the circuit. The battery contact comes in various shapes and sizes depending upon the type of battery; for a 9V PP3 battery, the type of contact used would be a press stud. There are typically two connections in a battery that are positive and negative. A proper battery contact will always have two terminals. Battery contacts have now developed a lot and become some of the most convenient and important electrical components. 

When there is no battery contact, the circuit or the load will not work with the battery. How a bridge connects two places, this battery contact here acts as a bridge between the battery and the circuit or other things that the battery is connected to as a source of power. Both the positive and negative terminals of the battery are required to create stable contact with the circuit.  

Construction of Battery Contact

While constructing a battery contact, you must consider the following things:

Size of The Battery

Remote batteries are smaller. It makes the distinction from batteries for computer systems. Therefore, a larger battery will need a larger battery contact. If a least tiny battery touch becomes of use, there is certain to be an unfastened touch.

The Type of Load

The type of load that the battery powers heavily influence which type of battery contact will be used. For example, in a TV remote, the batteries used are of small size because the remote only needs little power to operate. Therefore, smaller battery contacts are used. In contrast, the large device or load that uses larger batteries, like the 9V PP3 battery, needs larger battery contacts. Also, in the case of larger loads, better battery connectivity is needed.

Battery Position

Batteries come in two forms that are surface-mounted or built-in. It will affect the approach of production of the battery contacts. Battery contacts are not interchangeable. That is why the mounting function is a necessary part of layout-making plans.

Note Positive and Negative Sides of the Battery

When the placement of both terminals is not proper, then damage can occur.

Therefore, you should always choose the right shape and size of the battery contact suiting the battery.

After that, you can choose a material you like. Durability will depend upon the type of material that you choose. The material will also determine whether or not you will face corrosion at a later time. 

After choosing the material, you can make metal stampings.

At this point., take care to make certain you have concluded in your design sample. The stamping manner is irreversible. The process entails reducing the metals to the preferred shapes and sizes. Thus, you will now not need to waste resources in case of a failed design pattern.

After the stamping process is done comes the turn for plating the selected materials. Plating is a process in which other materials are added to enhance performance.

Types of Battery Contacts

Following are the four main types of battery contacts:

Surface Mounted Battery Contacts

This type of battery contact fits in less space and is present on the outer part of the device. It also provides the opportunity for easy installation for repair and maintenance purposes. 

Cylindrical and Spring Battery Contacts

This form of battery contact, like in a 9V PP3 battery Tesco, is inside the gadget or device body. It offers a delegated compartment for the batteries and saves space too. Examples include TV remotes and walkie-talkies.These sorts of contracts permit tremendous versatility to clients. They provide firmness for batteries.

PC Battery Contacts

As apparent from the name, these types of battery contacts are designed for personal computers. The design of these contacts may differ depending on the computer’s brand. Such types of contacts contain battery compartments dedicated to the computer. The 9V PP3 battery contact Screwfix is some of the best quality contacts available out there. 

Enclosure Battery Contacts

Enclosure battery contacts are advanc and better versions of spring battery contacts. They occupy less space and are easier to install as compared to other contacts. They are use for remote hand controls because of their compact nature. Enclosure battery contacts are use in almost everything used today, like wristwatches, digital timers, cars, remote control, and many others. The best 9V battery contacts are provided by manufacturers such as Screwfix, Tesco, Wilko, Asda, Sainsbury’s, etc. 


In the above sections, we discussed the construction of battery contacts and how important they are in electronics. The material and the type of battery contacts you choose will highly impact the durability and efficiency of performance. Therefore, always be careful in your selection to make sure you purchase the right battery contacts
