Batteries are a crucial component of any TENS Unit. Without a battery, the device has no power and can’t function. However, there are various types of batteries that you can buy for your TENS Unit – or that might come with it when you purchase it – and they all have different properties that make them suitable for particular needs.
Types of Batteries for Tens Units
Mains Powered Batteries
The most common type of battery used in TENS Units is a mains-powered battery. These are known as ordinary batteries or ordinary alkaline batteries. Mains-powered batteries are the easiest to find, and they are the most common type of battery that comes with TENS Units. However, they can cause problems when used with an electrotherapy device like a TENS Unit. They can overheat and leak acid when using them with an electric current.
Rechargeable Batteries
Rechargeable batteries are also standard in TENS Units due to their cost-effectiveness and eco-friendliness. The three most common rechargeable battery types with TENS Units are Nickel Cadmium, Nickel Metal Hydride, and Lithium-ion. Rechargeable batteries are helpful for those who want to save money on the cost of operating their TENS Unit, but make sure that you only use rechargeable batteries if your TENS Unit is made to be compatible with them. Compatible rechargeable batteries tend to have a slightly different design, with a small connector at the end of the battery fits securely into the TENS Unit’s unit. Make sure that your TENS Unit is made to be compatible with the batteries you are using.
9v Batteries
9V batteries are standard in TENS Units and can be used as mains-powered batteries in some circumstances. However, many 9V TENS Units don’t come with their 9V battery and instead require a separate 9V battery. In general, it is best to get a separate rechargeable or mains-powered battery to use with your TENS Unit instead.
Alkaline Batteries
Alkaline batteries are the most common type of battery used in TENS Units. However, they can leak acid and require special care to prevent this from occurring. If you do not wish to use alkaline batteries, then you should look for a TENS unit that is made to be compatible with an energizer or Duracell batteries.
D-Cell Batteries
Duracell, Eveready, Energiser, and other standard D-cell batteries are the most common battery used in TENS Units. However, these can leak acid and can be dangerous to use. Also, due to the need for special care with D-cell batteries, it is not recommended that they are used in TENS Units.
Lithium Batteries
Lithium batteries are relatively new on the market. They are also sometimes known as lithium-ion batteries, and they are ubiquitous in TENS Units that come with rechargeable batteries or can be used with rechargeable batteries. When buying lithium batteries, try to get the highest quality ones you can find to ensure optimal performance.
Nickel Zinc Batteries
Alkaline zinc-carbon batteries are relatively standard in TENS Units. They are also known as alkaline batteries, and they tend to be more potent than standard alkaline batteries. Any alkaline zinc-carbon battery will do if you want a higher power battery for your TENS unit. Make sure that you don’t get zinc-air batteries. However – these pose a danger to users of electrotherapy devices and should not be used.
Nickel Cadmium Batteries
Nickel-cadmium batteries are pretty standard in TENS Units. They are also known as rechargeable or NiCd batteries, and they can be recharged to be used again, making them relatively cost-effective. They also don’t suffer from the same problems that alkaline batteries do when used with TENS Units. However, it is still recommended that you use rechargeable lithium-ion batteries with your TENS unit instead if possible.
Nickel Metal Hydride Batteries
Nickel metal hydride batteries are relatively new on the market. They have a small connector at the end of the battery that fits securely into the TENS unit – so you will need to buy a new TENS Unit with its battery if you decide to use this type of battery. This type of battery is also not recommended for use with electrotherapy devices.
Which Is the Most Suitable Battery Among Them?
If you are looking for a TENS Unit, make sure that it is compatible with rechargeable batteries. If you plan to use rechargeable batteries, make sure that your TENS Unit is compatible with the type of rechargeable battery you want to use.
If you want to save money on the cost of operating your TENS Unit, and especially if you will be using it often and for long periods, then consider getting a unit with rechargeable batteries included. This will save you money in the long run. However, make sure that your TENS Unit is compatible with the type of rechargeable battery you plan to use. If you are looking for an eco-friendly device, then look for one compatible with lithium-based batteries. These do not pose the same danger when used with TENS Units as alkaline or nickel-metal hydride batteries.
Overall, it is best to look at the different features of each unit to find the one that suits your needs best.
Battery Life
The amount of time that a particular type of battery will last vary. The rechargeable types tend to have significantly longer battery life than the mains-powered ones, but some exceptions exist. For the most part, it is essential to make sure that you are using a battery with the same capacity as your TENS Unit’s battery. This is especially important if you have a TENS Unit with low battery life, as the battery may quickly drain to near-empty.
Compatibility
It is worth noting that most TENS Units are only compatible with the batteries initially designed to use. Be sure to check which type of battery your TENS Unit comes with and not use a battery from another product. Some TENS units are compatible with ordinary batteries, while others are specified for a rechargeable battery.
