A large number of industrial equipment installed outdoors faces extreme temperature changes all year round. Ordinary rechargeable NiMH batteries will rapidly lose capacity or even shut down when exposed to long-term high temperature or freezing environment, which brings frequent replacement and high maintenance costs to factory and project owners.
Our wide-temperature Ni-MH series solves this practical pain point by adjusting cathode raw materials and low-temperature resistant electrolyte formula. After years of mass production verification, these cells and assembled packs can maintain stable power output in both high-temperature desert areas and sub-zero cold mountain areas. We produce AAA, AA, SC, C, D standard cells, and accept customized combination packs according to customers’ equipment size and voltage needs.

| AAA | 500mAh - 1100mAh | 1.2V / 3.6V / 4.8V |
| AA | 1300mAh - 2900mAh | 1.2V / 2.4V / 3.6V |
| SC | 2500mAh - 3300mAh | 1.2V / 6V / 9V |
| C / D | 4000mAh - 10000mAh | 1.2V / 12V / 24V |
| Custom Packs | Customized | Custom combination |
Special anti-freeze electrolyte and high-temperature stable cathode ensure stable discharge in extremely hot and cold environments, no sharp voltage drop under long-time operation.
After 500 standard charging and discharging cycles, the battery still retains more than 80% capacity, cutting equipment maintenance expenses for long-term unattended devices.
Only less than 30% capacity loss after 28 days of room temperature storage, suitable for standby emergency equipment that rarely charges.
Pass overcharge, over-discharge, short circuit, vibration and drop tests, no liquid leakage or explosion risk under normal use.
Users can recharge at any remaining power without draining power completely in advance, greatly improving daily operation flexibility.
No mercury, lead or cadmium inside, fully meet RoHS and REACH environmental import standards of European countries.

Different regions have different climate characteristics and equipment demands, and our wide-temperature NiMH can match the project demands of buyers in all major global markets:
All batches of wide-temperature NiMH cells are equipped with complete certification documents to support customs clearance of various countries: ISO9001, ISO14001, CE, UL, RoHS, REACH, UN38.3 transport report, MSDS, IEC test report. We can provide scanned copies together with bulk shipment files.
If standard single cells cannot match your equipment size, voltage and wiring requirements, our engineering team provides one-stop customized service. We can adjust cell combination, plastic shell, wire length, terminal type, and add NTC temperature protection components as required. Small sample orders are supported for performance testing before mass production.
Q: What temperature can these batteries withstand when charging?
A: Charging environment needs to be controlled within 0℃ ~ 70℃, discharge range can reach -40℃ ~ 85℃.
Q: Can I use these batteries for solar street lights?
A: Yes, a large number of solar project customers from Middle East and Africa place stable orders for this series every month.
