Many outdoor devices installed in Middle East, Africa and southern areas will stay exposed to direct sunlight all year round. Ordinary rechargeable batteries will decay rapidly under long-term high temperature, leading to frequent replacement and increased project operating costs.

Our core model H-AAA600 3.6V high-temperature NiMH pack adopts special high-temperature resistant cathode material, strictly tested per IEC 61951-2 standards. It can keep stable capacity output under continuous 85℃ working environment, and still maintain over 70% capacity after long-time standby. We supply standard 3-string AAA finished packs and support various series-parallel customized battery modules.

85℃ High Heat Stability

Specially optimized positive powder slows electrolyte volatilization under long-time high temperature, capacity retention above 80% at 85℃ continuous discharge.

500+ Service Cycles

Internal electrode anti-attenuation design reduces capacity decay during repeated charge and discharge cycles.

Low Monthly Self-Discharge

Only less than 30% capacity lost after 28 days room temperature storage, fit standby monitoring equipment.

Full Sealed Anti-Leak

Pass overcharge, short circuit, vibration and drop safety test, no leakage risk in hot outdoor environment.

No Memory Effect

Users can recharge at any remaining power without complete discharge in advance.

1C Stable Discharge

Support continuous 600mA discharge, voltage platform stable without sudden drop.

Global Compliance

RoHS, REACH, UN38.3, CE, UL certified for all country import.
