Rechargeable AA Batteries with LCD Charger, 1.5V 3400mWh High Capacity, Li ion Batteries, Lithium Rechargeable 4 Packs with 2H Fast Smart Charger 1500 Cycles

Got this for my blink doorbell camera and I’m tired of exchanging the batteries every two weeks

So far I am pleased with these batteries. I use alot of trail cameras and outdoor devices and these so far.. have held up. One thing that I feel is a marketing trick and I DONT LIKE is the new MWH labeling to make a battery look powerful. Being new this DECIEVES a customer. Batteries are commonly rated with MAH .. AMP hours not WATT. These are still strong, however to give you an idea, solar outdoor lights go from 300 to 800 amp hours where as a camera or nice toy goes from 2500 to 3200 amp hours. These particular batteries range around 2266 MAH which is still strong however the 3400 MWH is a play on marketing. Overall decent .. just know what your using them for and the requirements

I needed a strong set of AA batteries for a drone controller, these batteries fit the bill. They outlast the drones 23 minute charge so I never loose contact with the drone. They are easy to recharge with a standard USB charger. Thank you for a great battery. Don

I like using rechargeable batteries in some things, but unlike NiMH batteries that are only 1.2 volts, these lithium ion batteries are a full 1.5 volts. They came fully charged reading at 1.51 volts with a battery tester. There are restrictions on using only this charger for these batteries, and that the charger should not be used for any other batteries than these. I don't like the fact that they should be charged every 30 days to prolong their life, as if I'm going to remember with so many batteries in so many things, these days. So it will be best to put them into something that gets a lot of use and needs recharging, often.

I was full of excitement when I first acquired a rechargeable battery pack. Regrettably, my experience with it did not match my expectations. After using it only once, the battery pack failed to work, and when I tried to charge it, it didn't respond. This came as a disappointment to me. If I could return it I would but unfortunately, now I'm out of that money.

These lithium ion batteries charge up quickly and the charger shuts off automatically while not getting too warm. I am in the process of converting my staple of nickel metal hydride batteries to the new lithium technology. These registered 1.5 volts each and seem to be capable of powering almost any device. Took about 2 hours to recharge. I haven't yet tried other batteries in this charger, only the 4 AA's that were included. No issues yet after using them with my equipment for just a few weeks. We'll see how they hold up over the next few months. For now I'll rate these 4 stars, and will come back to update if anything changes.

These are some pretty rad rechargeable AA’s. I’m using them to fuel the controller for this RC toy car I enjoy playing with- these last 2-3 times longer than the disposables I was blowing through originally. Takes about 90 minutes to get them back to full. I’ve been draining and recharging them almost daily for a month; have not seen a difference in the longevity of the power :) The charging case is a good portable size/weight; holds the batteries snuggly so I don’t have to worry about everything falling apart when tossing this in my bag. There are light indicators that turn green with a full charge- uses a usb C making the recharge process pleasantly speedy (does not come with a block). Bottom line is, i spent about the same amount this pack costs on disposables in two weeks. It just makes sense to go with rechargeable. I have no complaints :)
