Compared with ordinary Ni-MH batteries, our high-temp series uses optimized cathode materials, low-temperature adapted electrolyte, and a fully sealed structure. This design helps reduce capacity loss in high heat, improves performance in low temperatures, and supports long-term standby operation for equipment that cannot be easily recharged or replaced.
1.Product Introduction
We are a professional manufacturer focused on the R&D and production of wide-temperature Ni-MH rechargeable batteries and custom battery packs. With more than 15 years of experience in the battery industry, we have developed a product line that covers standard cells, assembled packs, and custom solutions for industrial, commercial, and outdoor energy storage applications.
High-temp Ni-MH batteries are particularly suitable for equipment exposed to large temperature fluctuations. In many real-world scenarios, batteries must work under direct sunlight, desert heat, cold nights, high humidity, or long-term standby conditions. Ordinary Ni-MH cells may experience reduced voltage, lower capacity, shorter cycle life, or even failure after prolonged exposure to these environments.
Our wide temp NiMH batteries are built to minimize these risks. The product series supports standard sizes such as AAA, AA, SC, C, and D, and can be assembled into different voltage and capacity configurations according to customer requirements. This makes them suitable for both off-the-shelf projects and custom-designed industrial battery systems.
Typical product categories include:
- High-temperature AAA Ni-MH cells
- High-temperature AA Ni-MH cells
- High-temperature SC Ni-MH cells
- High-temperature C Ni-MH cells
- High-temperature D Ni-MH cells
- Custom Ni-MH battery packs
- Wide-temperature rechargeable battery modules

3. Key Features of High-Temp Ni-MH Batteries
1. Ultra-Wide Temperature Performance
One of the most important advantages of high-temp Ni-MH batteries is their wide operating temperature range. They can work from -40℃ in cold environments up to 85℃ in high-temperature conditions. This makes them suitable for desert areas, cold regions, outdoor installations, and equipment that operates under direct sunlight.
2. Long Cycle Life
These batteries are designed for repeated charging and discharging. With proper use, they can reach more than 500 cycles, which helps reduce battery replacement frequency and lowers long-term maintenance costs for industrial devices.
3. Low Self-Discharge
High-temp Ni-MH batteries maintain relatively low self-discharge during storage. After 28 days of storage at room temperature, the capacity loss is typically ≤30%. This feature is useful for backup power, emergency lighting, and equipment that remains in standby mode for long periods.
4. No Memory Effect
Users can recharge the battery at any remaining power level without worrying about capacity memory effect. This provides more flexible operation compared with some older rechargeable battery technologies that require full discharge before recharging.
5. High Safety Performance
The battery structure is designed with sealing and safety protection features. It has passed tests related to overcharge, over-discharge, short circuit, vibration, and drop, helping reduce risks such as leakage or explosion under normal operating conditions.
6. Eco-Friendly Composition
High-temp Ni-MH batteries are designed to reduce the use of harmful substances such as mercury, lead, and cadmium. They can be used in projects that require compliance with international environmental regulations.
7. Stable High-Rate Discharge
These batteries support continuous discharge up to 1C, which means they can deliver relatively stable current for devices that require instant or continuous power output. The voltage platform remains stable during discharge, helping avoid sudden power drops.
4. Detailed Feature Description and Application Scenarios
Wide Temperature Performance
The wide-temperature performance is achieved through material and structural optimization. The battery uses high-temperature stabilized positive electrode materials and low-temperature adapted electrolyte, which help maintain better capacity retention in extreme environments.
At 85℃ continuous discharge, the battery can still maintain over 80% capacity. At -40℃, it can release more than 70% of the rated capacity. This is critical for equipment installed in deserts, mountains, cold storage areas, outdoor farms, and remote monitoring stations.
Cycle Life and Cost Efficiency
For industrial equipment, battery replacement is not only a cost issue but also a maintenance issue. High-temp Ni-MH batteries support 500+ cycles under standard test conditions, which makes them suitable for devices that require long-term operation. This reduces the need for frequent battery changes and improves the reliability of unattended equipment.
Low Self-Discharge for Standby Equipment
Many industrial devices, emergency lights, and remote sensors are not always in active use. They may stay in standby mode for weeks or months. Low self-discharge helps preserve battery power during storage, so the equipment can still work when needed.
