These 1.5V rechargeable lithium AA batteries are best for devices that want alkaline-like voltage, especially Xbox controllers, Blink cameras, smart locks, and other higher-draw gear. The built-in holder doubles as the charger, which makes the set convenient, and several reports say runtime is strong, with some devices lasting weeks or months and holding 1.5V better than NiMH cells. The main cautions are the sudden drop-off at end of charge, limited warning before shutdown, and the need for the right lithium-compatible charger and charging habits. A few packs also arrived dead or failed after a short time.

Common Questions (5)

  • They can last much longer than NiMH cells in higher-voltage devices, with reports of weeks to months of use in Xbox controllers and smart locks, and several months in a Flume leak detector. In Blink cameras, they work well for some setups but may still last less than disposable Energizers in harder-to-reach cameras.

  • Yes, the case is meant to be powered by USB-C and the listing calls for a 5V/3A supply. A lower-amp charger will still work but can take all day, while a charger above 3A is generally fine because the device only draws what it needs.

  • Yes. They hold a steady 1.5V until the internal cell is depleted, then can shut off abruptly, so devices may give little or no low-battery warning. That makes them great for devices that want full voltage, but less predictable for gear that depends on gradual voltage decline.

  • No. They need a charger designed for 1.5V lithium cells, and using a NiMH charger can overcharge the wrong chemistry and create a fire risk. A proper smart charger or the included charging case is the safe option.

  • A test with an XTAR VX2 Pro measured about 2000-2100 mAh, or roughly 2800-2900 mWh, at a 300mA discharge rate. That is below the headline 3000mWh claim, but still enough to outperform many NiMH AAs in devices that need a full 1.5V output.

Holder/charger with batteries is a great deal. Good pricepoint, but no experience with this brand.

Coupert Chrome extension auto-filled a few coupon codes. I don't know which it was, but one still worked for $10 off.

I'm interested in how much self discharge they have? I get Low Self Discharge (LSD) NiMh batteries like Duraloops, etc. so they can sit. I'd get these easily if they can sit for extended periods before losing much charge.
The buck converter will always be putting a drain on the cells.

Except mah is a bogus unit. It only makes sense when the voltage is the same. By itself It's not unit of energy nor power Not sure why people even using it. Except to make your number look bigger.
WH is it an actual unit of power.
Watt is an unit of power, Watt*hour is an unit of energy. Just saying.

Can anyone say how these work in Xbox controllers?
I've been using lithium AA recharables on my Xbox controllers for about 4 years now. One warning for mine is that i usually get no warning, and it dies mid game so something you should be aware of. Definitely a YMMV situation as I've never gotten a low voltage warning then a sudden controller death. Only has happened maybe 3x in the 4 years as all the other times I rotate them out to charge before that situation occurs. It usually goes a few weeks to a few months based on my amount of playing before I actually run out of juice.

The descriptions states: The Mupoer Rechargeable AA Lithium Batteries comes with 8 AA batteries included (3000mWh) plus the charging storage box
Why the down vote? Read the item description, it says included... Some people have no common sense in here.

I used these in my kwikset electronic door deadbolt and the batteries last much much longer. No error messages about battery type. Full power all the time and so far lasting 2x as long as regular batteries.
Just be mindful to replace them before they run out of juice. There's not much warning of when they will run out.

Because he was saying that this battery was not in the YouTube video, don't know what you're talking about with the description. 🤣
