Why This Series
Four things every cell in this series gets right.
SGS-verified under IEC 61960-3. The highest capacity rechargeable AA we have found, and 32% more than the best NiMH AA (BONAI / EBL class, 3,360 mWh).
Regulated 1.5V for most of the charge, dropping to about 1V near empty. NiMH spends most of its discharge near 1.2V, which some devices read as low.
Each slot's status on one screen: charging, FULL or error. See at a glance which cells are done.
About 2.5 hours from a 5V/3A USB-C source, all 4 cells in parallel. Any USB-C phone or laptop charger powers the case.
The Story
Power Reimagined.
Five ways the SCIGOLD AA 1.5V platform changes what a rechargeable AA can be.
01 · Massive Power Output
4,440 mWh
Longer runtime. Stronger performance. Built for high-drain devices.
SGS-verified under IEC 61960-3. The highest capacity rechargeable AA we have found, and the only one whose capacity is SGS-measured. 32% above the best NiMH AA (3,360 mWh).
02 · Steady 1.5V Output
Steady 1.5V.
For Most of the Charge.
NiMH starts near 1.4V, then spends most of its discharge around 1.2V. SCIGOLD holds a steady 1.5V for most of the charge, then drops to about 1V near empty.
Devices built for alkaline AAs get about 1.5V instead of NiMH's 1.2V. Battery gauges still vary: Microsoft notes that the accuracy of the Xbox controller's battery indicator can vary with battery type and brand.
SCIGOLD 1.5V Li-ion
A built-in regulator holds the output at about 1.5V for most of the charge; near empty it drops to about 1V. A device's low-battery warning may come late, so recharge on a schedule.
Alkaline
Voltage declines gradually from first use. High-drain devices see the biggest sag — flash recycle slows, motors weaken, brightness fades.
NiMH
A fresh cell starts around 1.4V, then spends most of its discharge near 1.2V. Some devices tuned for alkaline read 1.2V as low and warn early, while the cell still has charge left.

03 · Slim Pocket Charging Case
Charge & Store
Anywhere You Go.
About the size of a deck of cards. A flip lid closes over the cells. Charger and storage in one object.
Each slot checks its own cell and flags one that is faulty or not supported. The LCD shows every slot's status: charging, FULL or error. Fits a coat pocket — and your travel kit.
04 · USB-C Case Charging
Optimized. Protected. Full in About 2.5 Hours.
USB-C 5V/3A refills 1–4 cells in about 2.5 hours. From laptop, power bank, car charger, or USB-C wall plug.
Charger protection: over-charge, over-current and short-circuit protection, plus faulty-battery detection. Each cell also has its own BMS.
05 · Powers Everyday Devices
Gaming. Photography.
Home. Travel.
3.5 A peak discharge per cell (2 A continuous), for game controllers, camera flashes, headlamps, remotes and toys. For a smart lock or security camera, check its manual first.

SCIGOLD capacity measured by SGS under IEC 61960-3 at 23°C ± 2°C. Competitor figures are manufacturer-reported and were not tested by SGS. imuto's 1,600 cycles is the figure on its own store for its 3,600 mWh AA. imuto's 4,200 mWh AA and its 2,500+ cycles are from its Amazon listing (B0GFDPLGF8, checked September 2026). Energizer gives no mWh figure for its Ultimate Lithium AA: its L91 datasheet's constant-power chart shows roughly 4,200 mWh at a 1 W draw and 5,000 mWh at 0.1 W, and we use about 4,500 mWh.
