TEMIBATTBatteries AA Size 8 Pack, 1.5V 2600mwh Rechargeable Lithium lon AA Battery, Longer Lasting Li-ion USB AA for Toys, Remote Control，Blink Outdoor Camera

I have purchased these before and totally trust them. Fast charging as well.

Great product light weight and very powerful

These have a c style charging port built in

Good

Thought these would be great for my blink security cameras but I was sadly disappointed. They don't keep a charge long at all. On my cameras that go off alot I had to change them and recharge daily. For me it's a waste of money.

1.5v great power, the direct usb cable charging, very convenient.

We have long been users of both traditional non-rechargeable alkaline batteries and rechargeable Ni-MH batteries, with varying degrees of success depending on the particular application and task.That said, a few years ago, we began replacing our existing AA and AAA battery stock with lithiums (Li-ion) batteries of both the traditional (non-rechargeable) and the rechargeable type, the end result of which has been an overall better-than-expected experience.The above notwithstanding, thus far, these TEMIBATT AA lithium batteries have met our expectations and offer a fair value at their current $13.99/4 (about $3.50 each) price point.

I have a few things that take AAs but got tired of always having to change them when they died. And everything I charge is USB-C now, so I found these rechargeable batteries. They charge fairly quick and last a decent amount of time, longer than the alkalines I replaced. And the split USB-C cable is handy to recharge them all at once. Because they were used in low-draw electronics, I only charged thm a few times while I had them.However, about a year and a half later, one will not take a charge. The status LED flashes quickly and will change to solid if I wiggle the cable plug in the little socket. So, I guess that one is dead and there's no warranty to speak of. Sorry cannot recommend even at a Cyber MOnday price.
