High Temperature Battery Pack Solution
CMB is experting in research and study rechargeble batteries capable of operating in a high temperature environment to power GPS car trackers ,high speed motors and drilling exploration equipment.The normal li ion batteries work temperature is -20°C~60°C.When the work temperature 60°C,it belongs to the high temperature and when the work temperature -20°C,it belongs to low temperature.But CMB’s high temperature battery packs work at -40°C ~85°C.It ‘s also called wide range temperature batteries.
CMB has been provided with battery packs for different industrial applications. We have expertise in crafting high temperature lithium ion batteries for a lot of outdoor IoT devices including but not limited to:
- GPS car trackers (For famous car or electric car companies)
- Outdoor sensor system for trucks
Hightlight Advantage of CMB’s High Temperature Lithium Batteries
- CMB’s engineering team own the experience on new battery technology such as heat insulation and heat diffusion layers to support the temperature over 85°C
- The warranty is 1~5 years according to your specific li ion battery packs solution.Besides,the warranty is 3 years for the GPS car trackers.
- Before the shipment.CMB will do the high temperature in CMB’s Lab.
The Features of High Temperature Lithium Batteries :
- The operating temperature of discharge: -40°C ~ 85°C/-40°F~185°F
- The operating temperature of charge:-20°C ~ 60°C/-4°F~140°F
- The high temperature lithium battery works at +85°C /185°F but the standard lithium ion battery pack works at 85°C damaged even fired.
- When your devices have high discharge power, the engineering team of CMB adopts the cooling ribs and the latest pack workcraft to reduce the temperature.
- The use of more advanced structure design, such as heat insulation and heat diffusion layers, can help reduce the risk of thermal runaway in high-temperature batteries in high-temperature environments.
3.7V 2600mAh High Temperature Batteries for IoT Devices

CMB’s 3.7V high-temperature lithium batteries are available in three capacities.
- 18650 2000mAh 5C discharge current
- 18650 2600mAh 15A discharge current
- 18650 3200mAh 15A discharge current
CMB uses the most advanced high-temperature battery technology and is designed for applications in specialized environments.
Our high-temperature rechargeable batteries are able to satisfy the need for their safety, puncture-proof, explosion-proof, water-proof, and fire-resistant characteristics, thus ensuring stable and long-lasting performance.
CMB’s high temperature 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.
