Welding Thickness: Since you will be making welding connections on small batteries, your spot welds are also going to be quite small in size or thickness. Generally, this ranges between 0.05 mm to 0.2 mm which is a decent enough range for most users. Welding Current: For properly welding and creating electrical connections with a battery, it is quite important to use a powerful battery spot welder. Thankfully, most battery spot welders offer a welding current range of 50A to 800A which is quite high for welding connections with a battery. Controls: Just like any other welding machine, it is highly important to set your battery spot welder to the right settings. Hence, most of them come with multiple dials, screens, and even foot paddles in some cases that you should check out before buying one.
Surely these factors can come in quite handy while picking the best battery spot welder for you. Although, if you want to buy the right one, you should also go through the features and specifications as well as the detailed “Buying Guide” regarding battery spot welders present down below so that you can choose the right one at the end.

Buying Guide for the Best Battery Spot Welders
Those of you who work on a lot of electrical circuits are also most likely soldering and welding a lot of connections together. And while most of them are quite easy to do, the same cannot be said about welding electrical connections with batteries. In that case, you will need to use something like the best battery spot welders present above. To help you out in picking the right one, we have explained all the features and details of these various battery spot welders. Now, we also have the following complete buying guide regarding battery spot welders in this listicle for helping you in your buying decision:
Welding Thickness
Since some batteries are quite small and others are large, you also need to change your spot welding size respectively. However, this is only possible when your battery spot welder also supports variable welding sizes or thickness ratings. As a result, most of them support a welding thickness range of 0.05 mm to 0.2 mm which should be fairly decent in most cases. You should be able to use the same for a large number of battery types and wire types with ease.
Welding Current
Whether you are using your battery spot welder for thinner connections or thicker ones, you would want it to make secure connections that stay intact for a long time. To ensure this, it is highly important to use a powerful enough battery spot welder that can properly spot weld all kinds of wires on all kinds of batteries. One easy way to check this is to look at the welding current offered by your machine. Generally, this will be given as 50A to 800A which is much higher than what you will need in most cases for making spot weld connections for your electrical circuit batteries.
Temperature Range
Even though not all battery spot welders have a temperature range mentioned, a few of them do which can be a great way to get an idea of its performance. This includes temperature ranges like 100 to 400 degree Celcius or 150 to 500 degree Celcius where a higher range is always considered to be better. With higher temperatures, you can easily work with most batteries and solder metals.
Work Cycle
All welding machines also have a rating known as work cycle which tells you about the time for which they can work at a given time. Usually, battery spot welders offer a work cycle of about 20 pulses within a minute. With this, you can easily spot weld a lot of batteries before waiting for the work cycle to refresh which is always great.
Supported Batteries
Before you go ahead and start using a battery spot welder, it is highly important to ensure that your welder is compatible with the batteries that you want to weld in a circuit. While there are a lot of battery types available out there, two of the most popular ones used in circuits include 18650 and 14500 batteries. As a result, almost all battery spot welders support welding these batteries along with a few others.
Controls
Even if you have a powerful battery spot welder, you will not be able to use it to the fullest if you do not have the right controls at your disposal. Hence, it is quite important to check the control options offered by a given battery spot welder. Other than standard dials and switches, a few models also offer display modules for ensuring that you are running your battery spot welder at the right power output. As for using the welder, most of them allow you to do this by either pushing the welding head upwards or by using an included foot pedal for ease of use.
Accessories
Similar to most other welding machines, to use your battery spot welder, you are going to need a lot of other tools and accessories along with it. Fortunately, almost all battery spot welders include a wide range of accessories in the box. This includes things like spot welder, foot pedal, battery holder, welding needles, wrenches and screwdrivers, fuse tubes, and nickel platings. If your battery spot welder also comes with all these, not only do you get a better value for money, but it also allows you to start using your battery spot welder right away.
Warranty
As spot welders and other welding machines do not come in cheap, you would want your battery spot welder to stay functional for as long as possible. Therefore, it is always a great idea to check the included warranty of your battery spot welder before buying one. Usually, you will find most of them to include a 1-year warranty which is quite decent.
