Sub-C (SC) is a cylindrical battery form factor with 22.5mm diameter and 43mm height, smaller than C size and larger than AA. It is widely used for high-drain power tools and RC models due to its balanced capacity and discharge performance.
Our standard SC NiMH cells support 1C continuous discharge. For high-drain demands, we also provide 5C high-rate SC NiMH cells for power tools and RC off-road vehicles.
Yes. We support custom nickel tab size, spot welding position, shrink tube printing and battery pack assembly. Free technical drawing support is available for bulk OEM orders.

All Weijiang NiMH cells are 100% tested for capacity, internal resistance and voltage before shipment. Below are representative performance curves and quality parameters for our standard NiMH cells.
Cycle Life: 80%+ capacity after 1000 cycles
Self-Discharge: 84% retention after 6 months @ 20°C
Discharge Voltage: Stable plateau at 0.2C–2C (D-cell representative)
