AA Rechargeable Batteries with Charger Kit,4 Pack 3300mWh Rechargeable Double AA Lithium Battery 1.5V,Smart Battery Charger AA AAA of Lithium/Ni-mh/Ni-cd

I’ve stopped buying alkaline batteries, they’re single use and all too quickly end up in the landfill. These high capacity lithium batteries are a great upgrade from disposable batteries! The included smart charger is a great bonus in this package. It instantly recognizes and appropriately charges all types and most sizes of rechargeable batteries. Although the ad doesn’t mention it does charge 18650 lithium batteries too. Recommended!

I love that these rechargeable batteries are done with a USB cord instead of putting them into a wall. This makes perfect for travel, for people who are on the go or for charging in a car.So far, they seem pretty good. They hold a charge well, and for the uses I have had to them, such as putting them in flashlights and LED candles, they seem to hold charges very wellI will try my best to test how long they last and how long they take to recharge.When recharging, you do have to make sure that they are all recharging at the same time so that they can complete the circuit.Additionally, I want to see if they do continue to hold a charge over lots of time. I have had sets of rechargeable batteries in the past that lose their charge over a few months or years, and I would like to see how long these hold up. I will do my best to update this review.The color of them is fine and it’s really nice that you can easily identify these rechargeable batteries versus the regular disposable ones. I’m hoping that this is going to be a much more eco-friendly way to power items that constantly drain battery power.

I'm so glad I decided to get this lithium battery charger. I have Blink security cameras in my home that go through so many AA lithium batteries. For me, this was a wonderful value. I can also not be shy with my camera settings now as I was trying to save the battery life. So glad they make chargers for lithium, I literally had no idea this product existed.

Only two of the batteries could take a charge. The other two batteries would not charge at all. The product still works.

Ordered this for my Ring cameras that take the lithium ion batteries. Figured it would be better to rotate them out than to purchase new ones every time. These should hold up.

This works well. The display is easy to read and provides lotsa good info on what is being charged, and how much charge it has. I took one star mainly because the housing for this feels a bit cheap. Long term, I’m not sure how durable this will be. I’m going to be careful not to drop it and to take good care of it—I don’t think it would handle a drop at all. It works well though. We’ve used it for several months with several different kinds of batteries—all of them charging great!

Included AA batteries charged with no problems.Battery case is a nice touch.Charger will also charge AAA batteries.

First, it's important to note that these are 1.5V batteries. Most rechargeable AA batteries are 1.2V, which is fine for most small devices, but my powered blinds take 8 of these connected in series to create a 12V supply to the motor. If I try to use standard rechargeable AAs (1.2V), I will only be providing 9.6V...not enough.These batteries charged fine...although slowly. The included charger will charge other battery sizes as well, and detects them appropriately.
