Let’s be real—regular AA batteries are so last century. These 4255mWh Rechargeable Lithium AA batteries are the ultimate upgrade, and I may never go back to old-school disposables again!First off, USB-C charging—finally! No more hunting for weird proprietary chargers; just plug in and juice them up fast. The constant 1.5V output means my gadgets stay powered without that slow, sad battery drain halfway through use.I’ve been using them in remotes, flashlights, and even my Blink doorbell cameras, and they’re performing like champs. Plus, with 2000+ recharge cycles, these things will probably last longer than my will to keep up with the latest iPhone models.If you’re tired of constantly buying batteries that just end up in a landfill, do yourself (and the planet) a favor—get these high-tech powerhouses. Your gadgets will thank you!

I needed some batteries for my rc controllers, and these work great especially since they are lithium they run at the same voltage as regular Duracell or energizer batteries. Most rechargeable batteries are 1.2 volt instead of 1.5 so it shows battery percentage low on devices when using nickel rechargeable batteries. The case charges the batteries and let's you know when each battery is fully charged. The money you save using these over regular batteries adds up over time also which is a the main reason I try to keep rechargeables on hand.

I read other reviews that mentioned these were compatible with Blink cameras, so I decided to grab some to try. Figured if they didn't work, AA batteries are always useful around the house. I put them in my Blink doorbell camera, and 2 outdoor cameras and they work perfectly! No low battery warning. Not sure how long they'll last, but now I set those outside cameras to highest sensitivity, and maximum recording time, and so far it's been a week and a half. Even if I have to change them out once every month, it's still better than paying $24 every 2-3 months for the disposables they recommend. Super happy with them.

These are solid alternative to disposable batteries, especially for high-drain devices like flashlights, remote controls, and security cameras. The inclusion of a USB-C fast charger makes recharging easy. One of the best things about these batteries is the 1.5V constant output, which ensures stable performance across different devices. Unlike traditional NiMH rechargeable batteries that gradually lose voltage as they discharge, these maintain consistent power, making them ideal for electronics that require a steady voltage supply. I used them in a Blink doorbell camera, and they performed well without the typical low-battery warnings that often happen with other rechargeables.The fast charging is another strong point. They recharge much quicker than standard rechargeable AAs, which is great when you need fresh batteries in a hurry. The claimed 2000+ charge cycles sound promising for long-term use, though only time will tell how they hold up after repeated recharging. Overall, these are a great investment for those who frequently go through AA batteries and want a reliable, rechargeable alternative. They work well, charge fast, and provide consistent power, making them a worthwhile choice for everyday use.

The manual says 0v refresh. However the charger does not support that feature, it’s not the sellers fault that the instructions are falsely written. One battery arrived 0.1V. The charger kept showing red meaning the battery is incompatible, bad or otherwise. I put it in another charger and the same thing happened. So I had to jump start it by using a low voltage Dc Power Supply (set to 3v) and it worked. Now it’s charging up fine. Overall as far as life span on all the batteries that’s to be determined. I needed these for a high power flashlight and so far so good.
