POWXSRechargeable AA Lithium Batteries USB, 3300mWh Super Capacity 2H Fast Charging 1.5V Lithium Ion Double A Batteries with 2 in 1 Micro USB Cable

I go through charge cycles on my batteries using my Xbox Controller constantly. I've had bad experiences with the branded lithium packs made for the controllers, so I switched to NiMH AA and those had been working well.Due to advantages with Lithium (storage life, capacity) I'd been meaning to try them for some time, but I just had no reason to abandon my NiMH. Finally, I decided to simply order some and give them a shot.I now rely solely on these Lithium, and I've been using them for 1.5 years without issue. The capacity rating on Lithium differs slightly from that of NiMH so it can be hard to compare 1:1.These batteries seem to last longer than the 2700 mAh batteries I switched from. I haven't clocked it much, but I'd estimate around 40 hours of controller time. Maybe more.One thing I wasn't sure I would be fond of is the direct charging using USB. It's very convenient to simply plug in the harness and plug that into a USB port. You can also charge them individually, rather than in pairs like many dock style chargers.Another thing that was pleasantly surprising is the weight. 2700mAh NiMH AA weigh quite a bit. Considerably more than a basic 1500 you buy at a local store. These Lithium batteries weigh noticeably less than the 2700 while seeming to last longer.Lastly, is the shelf life. NiMH batteries drain considerably as they sit, even when not connected to a device. These Lithium do not. I know when I charge my back up pair, they will be fully ready when it comes time to use them. Then I just charge the pair I just used and place those away when fully charged.I can't speak on the endless number of brands that are on Amazon, but these batteries have treated me wonderfully. I highly recommend them.

So far I'm liking these battery's a lot! Recharge time is around 2 hours and I'm getting about 3000Mha or so out of them. I use them in my R3 scanner and it will run all day scanning on a charge!

I’ve had these batteries for a few months and recharge them about six times so far they seem to be holding up well no issues so farI’m using these in an outdoor application and they’re seeing some pretty wide temperature swings so I will come back and update this review if anything bad happensSo far, I’m pretty happy with the purchase

Saves money on batteries. The charging cord that comes with it is a good addition. Unless you want a longer cord, then get a longer one.

I bought these batteries for my Oculus Go controller. The controller is really finnicky with conventional alkaline batteries, and even worse with normal rechargeable ones because of the voltage. These are 1.5V and they work perfect for that application. The only downside is that they don’t give any discharge indication, they just stop abruptly. They have high capacity and the USB charging is a nice feature.

I got these for my blink doorbell so I don't have to keep buying lithium batteries. They last about a month with heavy traffic.

One of the batteries was defective when it arrive and the three that worked they discharge very fast. Not a good product at all. Very disappointed

The media could not be loaded. I've purchased about eight sets of these AA rechargeables, as they are lithium and can power my outdoor security cameras. (cameras only take lithium) Then I started using them on everything else as the throw-away batteries needed to be replaced. I love that there is no waste.But.....when you've purchased as many of these as I have, you are bound to get a bad one. The photo is of a battery that has been charged and used several times, so not brand new. I plugged a pair in to recharge, and after a couple of minutes, we began to smell a chemical smell in the air. I went over to the batteries and lifted them with my hand to discover this one was very hot and smoking. I immediately unplugged and took it outside. Upon examination, I am SO VERY glad that I did not plug it and leave the room, there could have been a fire. So, keep an eye on them when you first plug them in. And don't leave them unattended.
