What kind of battery does a heated jacket use?
Jan 07, 2026
Hey there! As a heated jacket supplier, I often get asked about the kind of batteries that power these amazing pieces of clothing. So, let's dive right into it and explore the different battery types used in heated jackets.
First off, one of the most common battery types for heated jackets is the lithium - ion battery. These batteries are super popular, and for good reason. Lithium - ion batteries are lightweight, which is a huge plus when you're wearing a heated jacket. You don't want a bulky battery weighing you down, right? They also have a high energy density. This means they can store a lot of energy in a relatively small space. So, you can get a good amount of heat from your jacket without having to carry around a massive battery pack.
Another great thing about lithium - ion batteries is their long lifespan. They can handle a lot of charge - discharge cycles before their performance starts to decline. This is important because you don't want to be replacing your battery every few months. Most lithium - ion batteries used in heated jackets can last for several years with proper use and care.
Now, there are different voltages available for lithium - ion batteries in heated jackets. The most common ones are 7.4V and 12V. A 7.4V battery is usually a bit more compact and lighter, making it a good choice for jackets that you want to be as lightweight as possible. However, it might not provide as much heat as a 12V battery. A 12V battery, on the other hand, can deliver more power, which means your jacket can get hotter and stay warm for a longer time. But it's also a bit heavier and bulkier.
Some of our thermal hunting jacket models come with a 7.4V lithium - ion battery. These jackets are perfect for those who are on the go and need a lightweight option. Whether you're hiking, camping, or just running errands on a cold day, these jackets will keep you warm without weighing you down.

When you're out in the cold for long periods, you need all the heat you can get. The 12V battery ensures that your jacket stays warm throughout your hunting trip.


Another type of battery that's sometimes used in heated jackets is the lithium - polymer battery. Lithium - polymer batteries are even more flexible in shape compared to lithium - ion batteries. This allows for more innovative designs in the jacketing. For example, the battery pack can be made thinner and more contoured to fit better under your jacket.
They also have a lower risk of swelling or leaking compared to some other battery types. This is an important safety feature. You don't want to be worried about your battery malfunctioning while you're wearing your heated jacket. However, lithium - polymer batteries are generally a bit more expensive than lithium - ion batteries.
When it comes to charging these batteries, it's pretty straightforward. Most heated jacket batteries come with a charger that you can plug into a standard wall outlet. Some of our jackets also support USB charging. This is really convenient because you can charge your battery using a power bank or even your car's USB port.

Now, let's talk about battery life. The battery life of a heated jacket depends on a few factors. The first is the battery's capacity, which is usually measured in milliamp - hours (mAh). A higher - capacity battery will generally last longer. The second factor is the heat setting you're using. If you have your jacket on the highest heat setting, the battery will drain faster than if you're using a lower setting.
For example, if you have a 5000mAh battery and you're using the lowest heat setting, you might get 6 - 8 hours of heat. But if you switch to the highest heat setting, that time could drop to 2 - 3 hours. It's important to consider your needs when choosing a jacket and its battery. If you're going to be out in the cold for long periods, you might want a jacket with a higher - capacity battery or a model that allows you to easily swap out the battery.
As a heated jacket supplier, we're always looking for ways to improve the battery technology. We're working on developing batteries that are even more efficient, lighter, and have a longer lifespan. We also want to make the charging process even more convenient for our customers.
