The SCIGOLD Standard
Smart Charging Is GOLD.
Four standards behind every SCIGOLD 1.5V AA Li-ion cell.
What we print is what SGS measured.
Measured by SGS under IEC 61960-3, across 50 cells from 3 production batches. Other brands self-report their capacity.
4,440 mWh per AA
USB-C in. Steady 1.5V out.
The Pocket Case charges four cells from one USB-C cable and shows each slot's charging status on its LCD. A built-in regulator holds the output at 1.5V.
Full charge in about 2.5 hours
Made to recharge.
Our published test summary reports at least 70% capacity retention after 1,600 full charge and discharge cycles under standardized test conditions. Actual battery life varies with use, charging and storage.
1,600 test cycles
Protection built into every cell.
A BMS in every cell guards against over-charge, over-discharge, over-current, short circuit and heat. Fine for carry-on bags under FAA spare-battery rules.
