Wide Temperature Batteries: Keeping Reliable Power in Extreme Cold and Heat

Wide temperature lithium batteries designed for reliable operation from -45°C to +85°C.

Why Do Batteries “Slow Down” in Cold Environments?

Have you ever experienced a device becoming slow or suddenly shutting down in cold weather?

The problem may not come from the device itself — it may come from the battery.

When the temperature drops, the chemical reactions inside a conventional lithium battery become less active. The internal resistance increases, reducing the battery’s ability to deliver power. As a result:

• Battery capacity decreases
• Discharge performance becomes unstable
• Voltage drops faster under load
• Equipment may shut down unexpectedly

In simple words, the battery starts to “take a rest” when the environment gets too cold.

For applications working outdoors or in harsh environments, standard batteries may not provide the reliability required.

The Challenge of Extreme Temperature Applications

Many industries require batteries that can operate reliably beyond normal temperature ranges, including:

• Outdoor monitoring systems
• Telematics and tracking devices
• Industrial equipment
• Mining sensors
• Emergency communication devices
• Smart lighting systems
• Military and aerospace-related applications

These devices are often installed in locations where temperature conditions cannot be controlled. From freezing cold winters to high-temperature outdoor environments, the battery must continue delivering stable power.

A standard lithium-ion battery usually works well around room temperature, but its performance can decline significantly in extreme conditions.

Our Wide Temperature Battery Solution: Designed for -40°C to +85°C

To solve these challenges, we developed a wide temperature lithium-ion battery designed for demanding environments.

Our wide temperature battery can operate from:

-40°C to +85°C

This allows equipment manufacturers to develop products that maintain reliable operation even under extreme temperature changes.

Key advantages include:

✅ Stable Performance at Low Temperatures

At temperatures as low as -40°C, our battery maintains improved discharge capability compared with conventional lithium-ion batteries.

This helps reduce risks such as:

• Sudden power failure
• Short operating time
• Unstable device performance

✅ Reliable Operation in High Temperatures

For outdoor applications exposed to heat, the battery can continue working at temperatures up to 85°C, providing greater flexibility for product design.

✅ Long-Term Reliability for Critical Applications

When battery failure can interrupt data collection, communication, or equipment operation, reliability becomes essential.

Our wide temperature batteries are designed to support continuous operation in challenging environments.

Real Application Experience: Supporting Harsh Environment Equipment

Our wide temperature battery technology has already been applied in practical projects.

One one example is a battery-powered camera installed inside retail freezers in the USA.

Application Case: Wide temperature 18650 lithium battery powering smart retail freezer cameras in cold environments.

The application required a battery solution capable of:

• Working at low temperatures
• Maintaining stable power supply
• Supporting long-term operation

Through customized battery design and temperature performance testing, our battery solution helped the customer improve product reliability in real-world conditions.
