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)

Why this kit

The kit in four numbers.

01

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.

02

Regulated 1.5V

A built-in regulator holds 1.5V, with 3.5A peak and 2A continuous output per cell.

03

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.

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

Frequently Asked

Quick answers, before you buy.

What is the actual capacity of the SCIGOLD AA Li-ion Kit?

Each cell delivers 4,440 mWh — SGS-verified under the IEC 61960-3 standard. That makes it the highest capacity rechargeable AA we have found, and the only one whose capacity is SGS-measured. It is 32% more than the best NiMH AA (3,360 mWh). The kit ships with 4 such cells plus the Pocket Case, a 4-slot battery charger.

How long does it take to fully charge the case from empty?

About 2.5 hours from a 5V/3A USB-C source. The Pocket Case charges all 4 cells in parallel at under 450 mA per slot. A standard phone charger, MacBook, power bank, or USB-C wall plug all work. The cells have no charging port of their own; they charge only in the case.

Can I use SCIGOLD AA Li-ion in any AA-powered device?

In most, but not all. The output is a regulated 1.5V (not the 1.2V of NiMH), which suits devices made for alkaline AAs: game controllers, camera flashes, remotes, wireless mice and keyboards, flashlights and toys. Some makers advise against rechargeable AAs: Schlage, August, Yale and Kwikset for their smart locks, and Blink, whose battery cameras take non-rechargeable lithium AAs. We don't recommend SCIGOLD for those. For Xbox controllers, Microsoft lists alkaline (LR6) AAs and recommends rechargeable NiMH (HR6) for best performance; it does not list lithium, and it says the battery indicator's accuracy can vary with battery type and brand. Check your device's manual first.

How many charge cycles does each cell support?

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.

Is the Pocket Case TSA carry-on safe for flights?

Yes. FAA rules allow spare lithium-ion batteries under 100 Wh in carry-on bags, not checked bags; each SCIGOLD AA is about 4.4 Wh. The cells have UN 38.3 test summaries. The kit fits easily in a coat pocket or carry-on side pouch.

What's in the box?

1 × Pocket Charging Case (CW505, 4-slot, black ABS), 4 × SCIGOLD AA 1.5V Li-ion cells (4,440 mWh each), 1 × USB-C cable (braided), and 1 × printed quick-start guide. No USB-C wall adapter is included — bring your own (any 5V phone charger works).

How does SCIGOLD compare to Eneloop Pro?

Eneloop Pro is NiMH at 1.2V with ~2,600 mAh (~3,120 mWh) capacity. SCIGOLD is Li-ion at a regulated 1.5V with 4,440 mWh — that's 42% more energy, at the voltage alkaline AA devices expect for most of the charge. Eneloop is fine for low-drain devices; SCIGOLD suits high-drain gear such as game controllers and camera flashes.

Why is the verified capacity (4,440 mWh) better than competitors who advertise higher mAh numbers?

Capacity for rechargeable AA must be measured in mWh, not mAh, because voltage differs by chemistry. mWh = mAh × voltage. A NiMH cell rated '2,600 mAh' at 1.2V delivers 3,120 mWh of energy. SCIGOLD's 4,440 mWh at 1.5V works out to about 2,960 mAh — more total energy. Always compare in mWh for apples-to-apples.
