When talking about heated jackets, we often see the question like "How long will it last?" "Is the heating time long enough for my working hours?" To answer this question, you need a better understanding of the features determine the working time of the battery heated jackets- Battery, Heating Elements, and the proper way of Maintenance.

Battery
The power of the heated jacket comes from the battery, of course. As a part of the heating system, the battery's capacity plays an essential role, as it determines the working time of the jacket. At the same time, the battery’s working time will also be affected by other factors like temperature, and temperature, and humidity.

-Battery Capacity
The battery is expected to provide enough power when you are working or attending activities outside. Please take a look at the battery before you buy the heated jacket, and you can see the mAh (milliamp hours) marked on it. Most of the batteries on the markets are 5200 mAh /6700 mAh and can work for about 8 hours. And some batteries have a larger capacity, such as Venustas', which can provide power for 8-10 hours at low level.

-Material
The battery material is also an important factor. Lithium-ion batteries, for example, are widely adopted in the heated apparel industry, as they have a higher energy density, voltage capacity, and lower self-discharge rate than other rechargeable batteries. They are more stable and can be recharged hundreds of times. Compared to other types of batteries, lithium-ion batteries feature better power efficiency as the single-cell has longer charge retention.

-Other Factors
Outside factors such as temperature and weather will influence the heating time. Working in a cold environment may affect the battery's performance, as it can speed up the power consumption. Although all types of batteries will be affected by low temperature, lithium-ion batteries are the least affected ones on the market thanks to their stability. So if your heated apparel is equipped with lithium-ion batteries, it can last for a longer time than others when working outdoors during winter.

Heating Elements
The heating element is used to conduct heat. The thermal conductivity, which is determined by the material, affects the thermal efficiency of the heating element. Carbon fiber is an excellent material and the best choice for the heat-conducting part of battery heated jacket.

-The Number of the Heating Zones
Obviously, the more heating zones your jacket is equipped with, the more heat you get. But more heating zones means more power consumption. So if you need additional zones to provide heat, you may need to compromise the longer battery working time.

-Locations of the Heating Zones
Putting it in the core area of the body can ensure the efficient use of thermal energy and reduce the waste of power to extend the working time of the battery heated jacket. For the jacket, 5 heating panels are built in the left & right shoulders and abdomen and the mid-back to provide the exceptional warmth without wasting heat.

Maintenance
A heating system can be divided into 2 parts: a battery and the heating panels (in the apparel). In order to extend the lives of the products, the proper maintenance of the battery and the apparel is necessary.

-For the Battery

• Fully Charge before first use.
• Fully Charge every 3 months.
• Recommended operating temperate: 14°F to 86°F (-10°c to 30°C).
• Store the battery where the temperature is 77±2°F (25±2°C).
• Always remember to unplug the battery if long time no use.

-For the Apparel
Correctly store your heated apparel can prolong its life. When the days are getting warmer if you are going to store your heated apparel, keep it in a dry and clean place. Plus, the right way of washing can extend its life too.

Go out fearlessly this winter. A well-made and long-lasting heated jacket can keep you warm and toasty till you are home.
