These 1.5V lithium AA rechargeables stand out for devices that want alkaline-like voltage, especially Xbox controllers, Blink cameras, smart locks, and other power-hungry gear. The included holder doubles as the charger, which makes charging simpler, and the batteries are reported to hold 1.5V longer than NiMH cells. Runtime can be strong, with some setups lasting weeks or months. The main cautions are sudden drop-off with little warning, compatibility limits with the charger and chemistry, and occasional dead or failing cells. A practical option if you need full-voltage AAs and can handle the charging quirks.

Common Questions (5)

  • Reported runtime varies by device, from weeks in controllers to months in smart locks and several months in a Flume leak detector. They also maintain 1.5V longer than NiMH cells, but some users report steep drop-off at the end and occasional failures after a few cycles.

  • They work in Blink cameras, Xbox controllers, and smart locks, and the 1.5V output helps devices that prefer alkaline-like voltage. In smart locks and controllers they can last longer than NiMH cells, but they may shut off suddenly and some devices lose low-battery warnings.

  • The case is meant to be charged with a 5V/3A USB-C power supply, and a lower-amp charger will still work but can take all day. A charger with more than 3A is fine as long as the voltage matches, because the device draws only what it needs.

  • No. These are lithium-ion AA cells with built-in electronics, so they need a charger designed for 1.5V lithium batteries; charging them in a NiMH charger can damage the cells and create a fire risk.

  • Yes. The set includes a holder that also functions as the charger, so the batteries charge in the case instead of needing a separate charger. That makes it easier to store and recharge the pack together.

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. 🤣
