The Science
Don't trust specs.
Trust tests.
Most rechargeable AA brands inflate their specs by 30-40%. We commissioned SGS Testing Services — a 145-year-old independent authority — to verify our 4,440 mWh capacity under IEC 61960-3 standard.
The SCIGOLD Standard
Smart Charging Is GOLD.
Four standards every SCIGOLD cell meets before it leaves the lab.
Genuine
What we print is what the lab measures.
4,440 mWh per AA, SGS-verified under IEC 61960-3. 50 cells, 3 batches, σ = 1.8%. No marketing inflation.
Optimized
Built for USB-C, not 1980s docks.
USB-C direct on every cell. Smart BMS. Regulated 1.5V flat. LCD case. 2-hour full charge from any 5V/3A source.
Long-lasting
One cell. 1,600 charges. ~500 alkalines.
1,600+ cycles to 80% capacity. 5+ year service life. $0.005 per use vs alkaline's $0.40 — 80× cheaper.
Dependable
Tested by the labs your insurer trusts.
IEC 62133-2 · UN 38.3 · FCC · CE · RoHS. Overcharge, short-circuit, thermal protection. Carry-on safe.
