FAQ About TENS Unit Pads

Due to the technical nature of TENS units and the amount of information surrounding them, it’s easy to get confused. Remembering all the connection types and maintenance directions can quickly become overwhelming.

In order to clear up some of this confusion, we’ll answer some of the most common questions people have about TENS unit replacement pads. By the end of this section, you’ll be able to confidently make a decision about which pads are right for you.

What are electrodes?

Electrodes are the pads that connect to the TENS unit via wires. The pads are what transfers the electrical current from the machine to your body. The pads have a sticky gel on them to help them stick to your skin. Reusable electrodes for TENS units are a way to save money on an otherwise costly recurring purchase.

What should you expect from a quality tens pad?

High-quality TENS pads will have the following qualities.

  • The pads should provide good conductivity from the machine to your skin.
  • They should also be able to be used multiple times; this saves you money over the long term. The pads should use a high-quality adhesive glue that doesn’t stick to your fingers, which will allow you to place them more easily.
  • Some TENS pads cause skin irritation, however, a quality TENS pad will not. Additionally, they should have a cloth backing to provide comfort and flexibility.
  • Finally, you should look for resealable packaging. Resealing your pads will allow you to extend their life far more than if you left them out in the open.

What are common connection types for electrode pads?

Electrode pads come in three different connection types. There are button / snap-on, pre-wire / pigtail, and pin connection.

  • Snap-on connections have a snap-on button that connects to the lead wire of the TENS unit.
  • Pig tail connections have a small length of wire attached that makes it easier to attach to the TENS unit.
  • With a pin connection, the lead wire of the TENS unit is directly inserted into the electrode.

However, pin connections are not very common so you shouldn’t have to worry about them. Most pads will be either snap-on or pigtail.

The type of pads you buy will depend on the connection type supported by your TENS unit. Look at your machine’s documentation to find out which type it supports. If you’re still unsure, try contacting the TENS unit’s manufacturer.

What are common sizes for electrode pads?

In addition to the different connection types, pads also come in different shapes and sizes. Here is a list of the most sizes, in inches.

  • 2 x 2
  • 2 x 4
  • 2.75 Round
  • 4.5 x 6 Butterfly
  • 1.5 x 1.5
  • 1.5 x 1.3

What are common leadwire connection types?

TENS units typically have one of the three common pad connector types. They are 2mm pins, snaps, or alligator clips. The other end plugs directly into the TENS unit with a 2.5mm or 3mm jack.

Can you give examples of tens unit products or brands for each connection type?

TENS pads use three types of connections: snap-on, pigtail, and pin. The pin connection type is very uncommon, and you will have limited replacement pad options if you buy a TENS unit that uses the pin connection.

Button / Snap connections

  • Most HealthmateForever products use this connection type.
  • KEDSUM 16 Modes TENS Unit.

Pigtail / Prewire

Pin Connection

The pin connection type is not very common. In fact, it is difficult to even find an example of this type of connection.

Where can I buy replacement pads for tens units?

The best place to buy electrodes for TENS units is online. Online stores like Amazon, Walmart, Walgreens, CVS, and Rite Aid all offer a wide selection of TENS pads. You can also find them locally at a brick and mortar store, but the selection will be limited. To get the best selection at the best possible prices, you should purchase online.

How long do tens unit pads last?

The length of time your pads will last depends on several factors. Your skin type, climate, and how you use them will all affect their lifespan. All things considered, the typical lifespan of pads should be somewhere between 15 – 25 uses. You can slightly increase their lifespan with proper maintenance such as replacing the plastic film and resealing them after each use, however, you will eventually have to replace the pads no matter what you do.

How to care for pads?

In addition to the steps mentioned above, you can also extend their lifespan by applying a drop of rubbing alcohol and rubbing the pads against each other. If you’re looking for more information on getting the most out of your TENS pads, we have an excellent article on how to make TENS unit pads sticky again.

Will the pads work with my device?

Before buying pads, check your device to see what type of connection type it takes. For example, is it pigtail or snap-on? When looking at pads on Amazon, the seller will say what connection type it is. Just find pads that have the same connection type as your TENS unit. If you’re still unsure, most Amazon sellers have a list of compatible TENS units on the product page. You can always contact the seller directly if you need additional information, they will be glad to help you.

Can I extend the life of pads with gels?

Yes, gels are known to extend the life of pads and are trusted by many users. In addition to extending the life of the pads, gels also increase the conductivity of the pads which will improve the overall quality of the TENS treatment. Some good gels are the Parker Laboratories Spectra 360 Electrode Gel and the Tensive Park Labs Conductive Adhesive Gel, both of which have good reviews.

Should I use the TENS machine pads that came with my machine or a 3rd party brand?

TENS units themselves are fairly cheap, some being as low as $20. The majority of the cost of using a TENS unit comes from replacing the pads. If you are using the machine often, the cost of the pads can quickly add up. Brand specific pads can cost as much as $2 per pad, in comparison to 3rd party pads which will usually only cost about 40 – 50 cents per pad. For this reason, you may want to use 3rd party pads.

Where to place electrotherapy pads?

Where you place the pads depends on what you are suffering from and where the pain is occurring. For your convenience, we have a dedicated page for TENS pad placement with charts for each condition. This page will help you get the best possible relief by placing the electrode pads in the ideal position.

What is the best tens machine?

Rather than rack up credit card debt, it is better to buy a TENS unit that is within your means. We have a page that compares different TENS units by price, features, and technical specifications.
