SCIGOLD AA Li-ion Kit · 4 cells + Pocket Case
Power, reimagined.
Four 4,440 mWh AA cells at a steady 1.5V, and the case that charges them over USB-C in about 2.5 hours.
Inside the kit
More energy in every AA.
SGS-measured capacity, a regulated 1.5V output, 1,600 test cycles in our published summary, and one case that charges and carries all four cells.
SGS-measured
4,440 mWh a cell. Measured by SGS.
Each cell holds 4,440 mWh, about 2,960 mAh at 1.5V. SGS, founded in 1878, measured it under the IEC 61960-3 method at 23 °C ± 2 °C. Other brands self-report their capacity, so the competitor figures below are manufacturer-reported.
The 4-page SGS test summary is on our lab report page, linked under the buy button. The notarized SGS report is available on request from info@scigoldpower.com.
- The highest capacity rechargeable AA we have found, and the only one whose capacity is SGS-measured
- 32% more than the best NiMH AA (2,800 mAh, about 3,360 mWh)
- 42% more than Panasonic Eneloop Pro (about 3,120 mWh)
Steady 1.5V
A steady 1.5V, not a sagging 1.2V.
A built-in regulator holds the output at about 1.5V, the voltage devices made for alkaline AAs expect, for most of the charge. Near empty it drops to about 1V. NiMH cells run at 1.2V and sag as they drain.
So your devices get a steady voltage for most of the charge.
- 3.5A peak, 2A continuous per cell
- Protection against over-charge, over-discharge, over-current, short circuit and over-temperature
- Replaces alkaline and NiMH AAs in most devices; check the manual
1,600 test cycles
1,600 test cycles. At least 70% retained.
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.
- Cells certified to UN 38.3 and IEC 62133-2
Pocket Case
Charges in the case. About 2.5 hours.
The cells have no charging port of their own; they charge only in a SCIGOLD case: this Pocket Case or the 8-slot Home Case (CW508). Connect the case to a 5V/3A USB-C source and four empty cells are full in about 2.5 hours.
Each slot charges its cell on its own and stops when it is full, and the LCD shows every slot's charging status. Close the flip lid and the case carries the cells, too.
- USB-C input: a wall charger, laptop, power bank or car adapter
- Under 450 mA per slot, all four slots at once
- Made for SCIGOLD 1.5V Li-ion AA cells, not NiMH or alkaline
Where it's used
Gaming. Photography. Home. Travel.
3.5A peak (2A continuous) per cell drives high-drain devices such as camera flashes and game controllers, and the steady 1.5V suits remotes, wireless mice and kitchen scales too.
One kit for game controllers, camera flashes, and the headlamp, GPS and radio in a travel kit. Smart locks and battery cameras are the exception: most of their makers specify alkaline or disposable lithium AAs, so use what the manual says.
Why this kit
The kit in four numbers.
4,440 mWh, SGS-measured
About 2,960 mAh at 1.5V per cell, measured under IEC 61960-3. The highest capacity rechargeable AA we have found, and the only one whose capacity is SGS-measured.
Regulated 1.5V
A built-in regulator holds 1.5V, with 3.5A peak and 2A continuous output per cell.
1,600 test cycles
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.
Charges in the case
The Pocket Case fills four cells in about 2.5 hours from a 5V/3A USB-C source, with an LCD showing each slot's status.
Compatibility
Works with what you already own.
- Gaming
- Xbox wireless controllers and Meta Quest 2, 3 and 3S controllers.
- Home and office
- Remote controls, wireless mice and keyboards.
- Photo and audio
- DSLR and mirrorless camera flashes, and wireless microphones.
- Outdoor and travel
- Headlamps, flashlights, GPS units and weather radios.
- Around the house
- RC vehicles, kids' toys and kitchen scales.
- Not for
- Smart locks and Blink cameras. Schlage, August, Yale and Kwikset advise against rechargeable AAs in their locks, and Blink specifies non-rechargeable lithium AAs. For any other device, check its manual.
Good to know
- The cells have no charging port. They charge only in the Pocket Case or the 8-slot Home Case (CW508), and both cases take USB-C.
- No wall adapter in the box: any 5V USB-C phone charger works. The about-2.5-hour charge time assumes a 5V/3A source.
- In the box: 4 cells, the Pocket Charging Case, a braided USB-C cable and a quick-start card.
- FAA rules allow spare lithium-ion batteries under 100 Wh in carry-on bags, not checked bags; each cell is about 4.4 Wh.
- Competitor capacity figures on this page are manufacturer-reported; only SCIGOLD's are SGS-measured.
Specs & details
Every number, in one place.
Power Reimagined.
Not “4 batteries in a box.” The next generation of rechargeable AA — the highest capacity rechargeable AA we have found, and the only one whose capacity is SGS-measured, paired with the Pocket Case, a 4-slot battery charger that charges all four cells in parallel from one USB-C cable.
4,440 mWh per cell. Regulated 1.5V output. 1,600 cycles in standardized testing. A full case in about 2.5 hours over USB-C.
Key features
① 4,440 mWh Ultra Capacity + Steady 1.5V Output
SCIGOLD’s AA Li-ion uses next-generation lithium-ion technology to deliver 4,440 mWh per cell with a regulated 1.5V output that holds for most of the charge and drops to about 1V near empty. Compared with traditional 1.2V NiMH batteries, that is more energy per cell at the voltage alkaline AA devices expect: game controllers, VR controllers, DSLR cameras and external flashes.
② Cycle Testing — 1,600 Full Cycles
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.
③ A Full Case in About 2.5 Hours
With 5V/3A USB-C input, the case fills 1–4 cells in about 2.5 hours. Power the case from anything that charges your phone — laptop, power bank, car adapter, USB-C wall charger. The cells have no charging port of their own; they charge only in the case, and the case needs nothing but one USB-C cable. No proprietary power adapter, no AC brick.
④ Pocket Case — 4 Independent Charging Slots
The Pocket Case is the differentiator. Charger and travel container in one, slim flip-lid design that closes into a clean rectangle. Independent per-slot charging — each cell terminates at its own optimal voltage. Each slot checks its own cell and flags one that is faulty or not supported. The LCD shows each slot’s charging status: charging, FULL or error. The case’s protection covers over-charge, over-current and short circuits and detects faulty batteries, and each cell has its own BMS on top.
⑤ Built for High-Drain Devices
With 3.5A peak discharge (2A continuous) per cell, SCIGOLD AA Li-ion reliably powers high-current devices: Xbox controllers, Meta Quest 2/3/3S controllers, DSLR cameras, wireless microphones, flashlights, RC vehicles, electric toothbrushes, kids’ toys, remote controls, kitchen scales, wireless mice, outdoor gear. Smart locks and battery cameras are the exception: most of their makers specify alkaline or disposable lithium AAs, so check the manual.

How It Works
Full in about 2.5 hours. Four steps.
-
Drop the cells into the charger
Place your SCIGOLD AA 1.5V Li-ion cells into the 4-slot Pocket Case (CW505) or the 8-slot Home Case (CW508), matching the + and − terminals shown in each slot.
-
Connect a 5V/3A USB-C source
Plug a USB-C cable into the case and connect it to a 5V/3A USB-C source — a phone wall charger, laptop USB-C port, GaN brick, power bank, or car charger. No proprietary adapter needed.
-
Watch the per-cell status display
The Pocket Case's LCD or the Home Case's per-slot LED shows each cell charging independently. A nearly empty cell and a half-full one each charge on their own and stop when full.
-
Done in about 2.5 hours
A full case of cells goes from empty to full in about 2.5 hours from a 5V/3A source. Charging stops automatically when each cell is full. Unplug the case once charging is done; the cells can stay in it for storage and travel.
