- The charger's LED indicator only shows charging status (flashing green, static green, flashing red), not a specific charge percentage.
Dimension Scores
Batteries do not possess detection accuracy features; this dimension is not applicable to the product itself.
Batteries do not have connectivity or range capabilities; this dimension is not applicable to the product itself.
Batteries do not feature app control or integration with smart platforms; this dimension is not applicable to the product itself.
The batteries feature a 'smart protect chip' and 'explosion-proof module' for safety, and are rated for 2000+ cycles, indicating a durable build for repeated use.
Best For
- Xbox controllers and other gaming peripherals requiring stable 1.5V output.
- Video doorbells and smart locks that benefit from high capacity and consistent voltage.
- Flashlights and digital cameras needing sustained power for extended periods.

Not Recommended For
- Devices where precise, real-time battery level reporting is critical.
- Users who only have 5V/1A USB adapters available for charging.
- Applications where extreme cold weather performance is a primary concern, as lithium battery performance can degrade in low temperatures.
Watch Out For
- A user reported that the batteries did not hold their charge after about four months of use in a smart lock, requiring recharging before use.
- Devices powered by these batteries may not display accurate battery life, often showing full until the battery is almost completely drained, which is common for 1.5V lithium AAs.
- The 3-hour fast charging time is dependent on using a 5V/3A adapter; slower adapters will extend charging duration.

What Buyers Say
Despite a 4.3/5 rating from over 2,200 reviews, specific user feedback indicates potential issues with charge retention over time. The product boasts a high 3600mWh capacity and a consistent 1.5V output, which is a key advantage for many devices. The included Type-C charger is a plus, promising to fully charge 8 batteries in 3 hours. However, users should be aware that lithium AAs generally don't provide accurate battery level readings in devices.
“Ugh, these batteries worked okay for a bit in my smart lock, but after like four months, they just wouldn't hold a charge, had to keep recharging them. So annoying!”
Common Praise
- Consistent 1.5V output helps high-drain devices perform without voltage drops.
- 3600mWh capacity provides noticeably longer device runtimes.
- Type-C charging for 8 batteries simultaneously is convenient and fast.
- The charger also functions as a storage case, which is handy for travel.
- Low self-discharge rate means batteries are ready even after months of not being used.
Common Complaints
- One user reported that the batteries stopped holding a charge after about four months in a smart lock.
- Devices do not accurately display the remaining battery life, often showing full until nearly empty.
- The 3-hour fast charge requires a 5V/3A adapter, which might not be included or commonly owned.
- The LED indicators on the charger only show general status (charging/full/error), not specific charge percentages.
Ownership Tips
- The 80% charge retention claim after months of storage seems to hold up for initial readiness, but long-term capacity retention might be an issue for some users.
- The constant 1.5V output means devices will perform at peak until the battery is almost completely drained, which can be a sudden cutoff.
- The Type-C charging port is a modern convenience, but ensure you have a compatible high-wattage adapter for optimal speed.
- The charger's compact design makes it genuinely useful for keeping batteries organized and portable.
Frequently Asked Questions
Do these batteries have a memory effect?
No, as lithium-ion batteries, they do not suffer from the memory effect that can plague older NiCd rechargeable batteries. You can recharge them at any charge level without degrading their capacity.
Can I use these batteries in any device that takes AA batteries?
Yes, these batteries provide a constant 1.5V output, making them suitable for most devices designed for standard AA batteries, including high-drain electronics like gaming controllers and smart home devices.
How long do these batteries last on a single charge?
With a 3600mWh capacity, these batteries are designed for long running times. Actual duration will vary significantly based on the power demands of the specific device they are powering.
What kind of charger do I need for these batteries?
The package includes a dedicated Type-C charger. For the advertised 3-hour fast charging, you'll need a 5V/3A power adapter; a 5V/1A adapter will result in slower charging times.
Will these batteries show the correct charge level on my device?
No, 1.5V lithium AA batteries typically maintain a constant 1.5V until they are nearly depleted, so devices may show a full battery icon until close to the end of their charge.
Buying Guide
When you're looking at rechargeable AA batteries, you need to think about how much power they hold, how long they'll last, and how fast you can get them ready again. Lithium AA batteries like these offer a big advantage with their consistent 1.5V output, which is different from traditional NiMH batteries that start at 1.4V and drop quickly. This constant voltage can make a real difference for devices that are sensitive to power fluctuations.
3600mWh Capacity
This is how much energy the battery can store. A higher mWh (milliwatt-hour) means the battery will power your devices for a longer time before needing a recharge, similar to how a bigger gas tank in a car means more miles.
1.5V Constant Output
Unlike many rechargeable AAs that start at 1.4V and drop, these maintain a steady 1.5V. This is important for devices that perform poorly or stop working prematurely with lower voltage, ensuring consistent performance until the battery is nearly empty.
2000+ Cycles
This number tells you how many times the battery can be fully charged and discharged before its capacity significantly degrades. A higher cycle count means the batteries will last longer overall, saving you money and reducing waste in the long run.
Type-C 3H Fast Charging
This refers to the charging speed and connection type. Type-C is a modern, reversible connector, and '3H Fast Charging' means you can quickly replenish the batteries, getting them back into action without a long wait.
Alternatives
If you need more accurate battery level reporting in your devices, look for NiMH rechargeable AA batteries. If you require even higher capacity for extremely demanding applications, search for batteries with a higher mWh rating, potentially in different form factors.
