Rechargeable AA Lithium Batteries 1.5V AA Battery 2200mWh High Capacity USB-C Charge, 1 Hour Quick Charge Double A Batteries 4 Packs

Good battery

I was so impressed with these batteries that I immediately bought a second set for use in a power-hungry deadbolt that has been devouring AAs of both the NiMh rechargeable and alkaline variety.These batteries don't take much more than an hour to charge, and they deliver reliable over a longer period of time without noticeable drain. The two-headed USB-C cable is a nice addition, but you're going to get a faster charge if you use a single cable for each battery.I see these as being ideal for travel (because you can use a regular USB-C charger) and would be perfect for high-drain devices like camera flashes.I highly recommend these. Two thumbs up!

I charged for hours, the light was on the battery to show charging. Put in device and nothing. Stay away from these batteries. Returning immediately for refund.

I got tired of buying regular batteries because I have so many things that use them. I had constantly been rummaging for a good battery when a TV remote or mouse would stop working. Well I finally turned the page and got a battery charger and about 24 rechargeable batteries. Now I always have good batteries to use. These particular batteries are great because they don't need a charger, you just plug them into a USB power supply and presto - they charge. It was thoughtful to include a charging cable that does two at a time. there are four batteries so maybe another cable would have been good, though I am not complaining. I charged two up and I am currently using one in my wireless mouse. Works great and I am sure it will be a while before it needs charging again. I like this concept of portable batteries. Plus the plastic case that holds all the batteries and charging cable is awesome for portability reasons.

I have lights stuck in places where I need to see and was going thru batteries until I found product.Quite happy with this.

Work great!!!!

The media could not be loaded. These are actually rated at 1200mAh, not the 1400 printed on the case, which is confirmed on my tester which is about half the capacity of an alkaline AA battery.The benefit of these batteries is they will provide a steady 1.5 volts until dead, unlike an alkaline battery which will decrease it's voltage steadily over its lifetime.I've deducted 2 stars because right out the box brand new, one battery is already defective. 3 of the batteries charge up to 1.52 volts, and the bad one only up to 1.48. hopefully this will not be the fate of all of the batteries within a short period of time which would be very bad.Considering how the price of alkaline batteries has skyrocketed recently, these seem like a good alternative and will help keep batteries out of landfills.

Batteries dont work. Flat out. Just dont work.
