Everything Need To Know For High-Temperature Battery Technology

Are you looking for a reliable and long-lasting battery that can withstand extreme temperatures without diminishing battery lifespan? A high-temperature battery might be the ideal power source for you. In this blog post, we’ll discuss everything you need to know about high-temperature battery technology, including its pros and cons, how to choose the best battery for your needs, the different battery types available, and tips for care and maintenance. By the end of this article, you should have a better understanding of high-temperature battery technology and what it has to offer.

What is a High Temperature Battery?

High-temperature batteries are rechargeable batteries designed to withstand extreme temperatures. They are typically made of Li-ion or Ni-MH cells capable of delivering high levels of power and energy density. Generally, high temperature batteries can be divided into five levels: 100°C, 125°C, 150°C, 175°C, and 200°C and above.


Advantages of High-Temperature Batteries:

High-temperature batteries offer a number of benefits. They:

  • Perform well in extreme environments and are ideal for applications in temperatures over 60°C.
  • Offer higher energy density than conventional batteries, meaning they can deliver more power for longer periods of time.
  • Are more efficient than lead acid batteries and ordinary lithium-ion batteries, delivering more power for longer periods of time.
  • Have a long lifespan and are relatively low maintenance.

Disadvantages of High-Temperature Batteries:

Despite their many benefits, high temperature batteries also have a couple of drawbacks to consider. They:

  • Are more expensive, leading to prohibitive costs in some applications.
  • Require special care and maintenance to ensure they last as long as possible.

Different Types of High Temperature Batteries:

When selecting a high temperature lithium battery, it is important to consider the battery type, capacity, cost, and the environment in which the battery will be used. Each type of battery has its own advantages and disadvantages, so choosing the correct type for your application is important.

Lithium-Ion● Light weight
● High energy density
● Ability to deliver high levels of power
● Relatively low maintenance costs
● Long service life
● Expensive
NiMH● More affordable● Lower power density
● Not as powerful as lithium-ion batteries
● More difficult to replace
● Require special charging equipment
Lead-Acid● Very affordable
● Relatively low maintenance costs
● Long service life
● Very heavy
● Low energy density
● Not as powerful as other types of batteries

How to Choose the Right High-Temperature Battery?

  • Consider the temperature range in which the battery will need to operate, and select a battery that is designed to operate within that range.
  • Consider the voltage requirements of the application, and select a battery that can provide the required voltage.
  • Consider the application of the high temperature battery, and select a battery that is designed for that type of application.
  • Consider the brand of the battery, and choose a battery from a reputable brand.

Care and Maintenance of Rechargeable High Temperature Batteries

High temperature lithium batteries require regular care and maintenance. It’s important to keep them clean and free of debris and store them in a cool, dry place. It’s also important to charge them regularly and use the correct charging equipment when doing so.

10 Tips for Using High-Temperature Batteries

  1. Only use the compatible charger designed for your high temperature battery.
  2. Always read and follow the provided manual for your high temperature battery.
  3. Avoid short-circuiting the battery.
  4. Avoid exposing the battery to unnecessary extreme temperatures.
  5. Keep the battery clean and free of debris.
  6. Store the battery in a cool, dry place.
  7. Charge and discharge your high temperature lithium battery fully every three months.
  8. Make sure the battery is compatible with the equipment it will be used to power.
  9. Dispose of the battery properly.
  10. Troubleshoot any problems before replacing the battery.

Common Applications for High Temperature Batteries


Because they can withstand extreme temperatures while providing a high level of power and energy density, high temperature batteries are commonly used in SOS systems, GPS tracking systems, temperature sensors, and military equipment such as night vision goggles and communication devices.

CMB’s lithium high temperature batteries are also used in Telematics boxes (T-boxes) for such recognizable companies as Volvo and Continental.

Specifications and Advantages of CMB’s High Temperature Batteries

CMB’s high temperature lithium batteries have a charge temperature range of -20°C to 60°C and a discharge temperature range of -40°C to 85°C. Our high temperature lithium batteries can operate at 85 °C for 1,000 hours, while other typical lithium batteries would die or fail to work at that temperature. Even when CMB’s high temperature lithium batteries are operated at 85°C for 1,500 hours, they can still hold a 95% charge capacity.
