AA Batteries Rechargeable AA Lithium Battery, 1.5V 3000mWh High Capacity AA Lithium ion Batteries, USB Type C 2 Hours Quick Charge Double A Rechargeable Batteries 4 Packs

THIS... Is the Rechargeable Lithium AAA Batteries with Charger and something that I am really happy to have bought. I have a few small house items left that require AAA batteries, but mainly my front door lock needs them too... and because I really never use AAA batteries I never have them on hand! However, Now it is easy for me to swap them out for two on the charger without worrying. Battery life is good, and I still expect these to wear out over time...but they have saved me so much money in being rechargeable that they have already paid themselves off and the next ones off! Peace of mind and easy on the wallet, in a small platform! Deal!

it's pretty simple. you charge them up, they power your stuff for a while and then need charged again. no problems from me.

Got them in December and charged them. Used them in pairs to power two low draw EL wire devices (similar to LED light) for a couple of hours. So 10% of their capacity used? Removed them from the devices. Definitely not stored fully charged nor fully discharged. 9 months later 3 of 4 will take a charge. The charger makes a nice night light for a room.

I have a couple dozen NiMH stay-charged, rechargeable batteries (Amazon brand, Duracells, etc). They are great and I have used them for years. Unfortunately, the NiMH batteries only charge to 1.2V and takes 5-6 hours to recharge. Several of my devices need 1.5V to work, so the NiMH batteries won't do. These lithium batteries are amazing. They charge to 1.5V in less than 2 hours! Works just like AA alkaline batteries in my devices that require 1.5V batteries. Bonus is the super cool looking charger that allows the batteries to not get too warm while charging. My first set of AA lithium rechargeable batteries, and they impressive.

These batteries were exactly what I was looking for! I have a device that will alert me when the batteries get low, so that I have advance warning that they need replacement. Most rechargeable lithium batteries would not support that feature because they output a constant voltage until they are depleted. These genius batteries will slowly decrease the voltage to simulate what a normal alkaline battery would do. They also start at a higher voltage than rechargeable NiMH batteries do when full. This way the device has a way of knowing the percentage of battery life left. They also charge very quickly, and I love that they simply need a USB type c charger, or use the included cable to connect them to a USB Type A plug.

Looks impressive but the fact is one of the batteries was doa and will not charge but other wise the other three works ok too much of a hassle to return

I use these in a medical device every day. They last longer than a set of alkalines. Instead of throwing away 4 batteries every day, I just recharge these. They have saved me so much money. I’d guess that these have about twice the capacity of the alkaline cell replaced.The USB-C charging is easy and fast.Very satisfied

I have had these for a 2 months and finally decided to recharge them and now they don’t charge. When I put them in a control or my blink camera it shows red and that the batteries are dead even after charging for 12 hours
