SCIGOLD AA 4,440 mWh — Verified by SGS
SCIGOLD AA 1.5V Lithium batteries deliver 4,440 mWh of measured capacity, independently verified by SGS Testing Services using IEC 61960-3 standard discharge testing. This is 32% higher than NiMH AA (3,360 mWh) and 47% higher than the industry average (3,000 mWh).

How We Tested 4,440 mWh
Verification was performed by SGS Testing Services — a 145-year-old Swiss multinational testing authority operating in 140+ countries.
- Standard: IEC 61960-3:2017 (Secondary lithium cells for portable applications)
- Method: Constant current discharge at 0.2C rate to cutoff voltage
- Temperature: 23°C ± 2°C (room temperature)
- Sample size: 50 cells across 3 production batches
- Result: Mean 4,440 mWh, σ = 78 mWh (1.8% batch variation)

Why mWh (Not mAh) Tells the Real Story
Most rechargeable AA brands advertise mAh (milliamp-hours). This is misleading because:
- mAh measures current, not energy
- mWh measures energy = voltage × mAh
- 1.2V NiMH "2,000 mAh" = 2,400 mWh actual energy
- 1.5V Li-ion "2,000 mAh" = 3,000 mWh actual energy
So a 1.5V lithium AA with the same mAh delivers 25% more real energy than 1.2V NiMH. Read the full explanation →
