Rechargeable AAA Batteries USB C 1200 mWh Triple AAA Rechargeable Battery 1.5V AAA Lithium Batteries with 4-in-1 Charging Cable and LED Charge Indicator, 4-Pack

These rechargeable batteries are a total game-changer! No more buying disposables—they charge super fast (about an hour) right from my laptop or car charger. They last way longer in my flashlight, remote, and kid’s toys compared to regular batteries. The charging lights make it foolproof, and knowing I can reuse them for years saves money and hassle. Perfect for anyone tired of dead batteries!

Great, they work, awkward to charge but not so bad, I am using these in the 3 remotes now to test them, before I buy 4 more packs of these. I only use these in low power usage devices like remote controls and some of my medical metabolic measuring devices, still that's 16 rechargeable lithium-ion batteries I need plus an extra 4 for charged standby so I don't have to wait on charge cycles when they run low. The FireTV remote seems bad to drain batteries fast, it must be the Alexa stuff and the constant comms they do with the TV / FireTV Box.

After trying this brand’s AAs for my Meta Quest controllers, I came looking for the AAAs to power our battery-hungry TV remote, and a few other gadgets around the house. Same handy USB-C charging, no bulky charger, and they work perfectly with the charging block I use all the time. Can’t say yet how the total lifespan compares to other rechargeables, but they already beat disposables by a long shot! :-)

Cheap and easy to use. Last a long time. Charges fast with included cord. Use in any device. Perfect voltage. Charges 4 at a time.

Supera lo esperado. Las compre para los controles de la casa y termine reemplazando todas las baterías de todo en la casa, al igual de mis herramientas electeonicas

These batteries accurately provide 1.5v for the full length of their endurance - a definite improvement over standard batteries that produce decreasing voltage over time. However, the endurance of a full charge is very short - about six hours for a string of LED fairy lights. Charging is easy enough, though the angle of the charging port is a bit odd - it is NOT straight in towards the center of the battery, so be cautious inserting it until you get used to it. The indicator light on the + end of the batteries is very handy both for making sure you have the cable inserted right and for knowing when the batteries are charged.

The batteries don’t connect to the usb-c without force. This is my second purchase. I thought I might have just caught a bad one. I used the cable that comes with them. One of the batteries broke while trying to connect to the usb-c. There shouldn’t be any resistance when installing. They all have to be forced into the charging slot.

These are so awesome! Cheap, neat little gadgets. I'm using them in only a very low power TV remote right now, so I can't say how long they will last, but so far it's been a month or 2 and I haven't had to recharge them. It's so cool how the USB c just plugs directly in so there is no need for any sort of bulky battery charger. USBC is the future.
