Rechargeable Battery AA, 8 Pack 1.5V 1200mAh/ 1800mWh Lithium AA Battery with Charging Cable, Double AA Batteries for Blink Camera, Toy, Remote, Xbox Controller

This review will be updated in due course however from first impression of using just 2 of the batteries I am impressed. I used these in a portable "discman" CD player which playback often lasts less than 50 minutes on standard zinc carbon batteries however with 2 of these direct from box they seemed to last much longer, possibly over double the timespan of the ZC cells. Once depleted, I charged them using a USB port on my laptop and was surprised how quickly they actually charged up! The green charging indicator lights are great to avoid over charging.Given these cost only a few pounds more than NiMh rechargeable cells I would rather pay for these for their ease of use, charging time and overall functionality.

I accidentally ordered AA instead of AAA but I’m genuinely pleased with how these turned out, they charge well were reasonably priced, hold their power reliably and feel like good quality, I kept two as spares for my VR controllers (already have bought rechargeable AAs from another seller before) and donated the other two to my college so they wouldn’t go to waste.My only suggestion would be a simple charge indicator design such as a orange light for partially charged and green for mostly or fully charged which would make it easier to use.

Works well

First use and the battery terminal fell off. Appears to be manufacturing defect. Amazon doesn’t appear to have a process to replace or refund as I ordered over a month ago

Seem good so far, charging is fast with the supplied 4 way USB-A to USB-C cable. Charge lasts a long time with a stable output that drops very quickly when it runs out unlike standard Ni-Cad or Ni-MH cells that drop slowly, with these you get full power until the end. They work very well in devices that need the full 1.5V and standard rechargeable batteries struggle (as most are only around 1.25V). About half the price of others so seemingly good value too.

Good

These were purchased as replacements to my AA batteries that I'm recycling too many of these days. These batteries charged reasonably quickly and ran them for more than 6 hours a day for more than a week, powering some LED Christmas tree lights, and they were still running when I took the tree down.Needless to say, I'm very impressed so far. The longevity of these batteries has proven decent so far. If I had to make one criticism, I would have liked a second 4 in 1 USB-C charging cable with the purchase of 8 batteries.For devices that have a relatively low draw on the juice, I have no reservations in recommending these.

This is my first use of Lithium Batteries and didn't know what to expect. I have battery powered "fairy" lights to brighten a dark end of a room and have been using assorted NiMh batteries - many of them over 10 years old. Some of them were lasting just a couple of days before needing recharging. Unfortunately, these Lithium batteries last even less than that. Maybe higher power batteries would last longer but as they are just used for basic fairy lights I thought lower power would be ok. They come with their own USB charging lead which is good and recharge quickly. I don't know whether to get more powerful batteries (which are expensive) or stick to NiMh's.

These were at an excellent price and they were worth it. The have a long battery life when used in devices. Very convenient with USB C snap in and out. The money I will save is really wonderful!

I wanted cheap usbc batteries.I got batteries with a usbc port. Very happy with my new batteries haha.

So far these AA lithium rechargeable batteries have worked just fine. I say so far because I can't speak about their longevity just yet, but so far my experience has been positive. I am using these in a high powered LED flashlight without issue. They last a long time and recharge quickly. I like that they have the charging ports built in so you don't need a separate charger, and they come with a four place charging cord so you can charge them all at once. My only complaint is that it's a bit hard to see the charging light, especially in a bright room. It's inside the port and isn't very visible, but I'll get used to it. I like these so far and I will update my review if they don't hold up.

I like to use rechargeable whenever I can but certain devices like my electronic door lock requires a full 1.5v or it just won’t work. So far this set works fine in my lock.This set comes with a case that holds 8 cells so there’s always some place to store the 4-in 1 charger to recharge these batteries.One issue I’ve had is that the charge indicator light is small and dim so it’s hard to see if the indicator is on or off. Not a huge deal but there are others that have a much more apparent indicator.

I’ve tried rechargeable AA batteries that use wall units to juice up and I’ve come away disappointed with the heat, the functionality, the difficulty of using them, etc. That’s why I’m much more impressed with AA batteries that recharge via USB-C. You just plug them in and that’s all. There’s no extra wall unit to haul around with you – if it works properly to begin with.These don’t provide an exceptionally high amount of power (my EBL batteries are 2,800mAh and my Eneloop are 2,000 mAh), but these do give more juice than other USB-charging AAs I have that are 1733 mAh.Of all the rechargeables I’ve tested, these have the lowest number of advertised recharge cycles (1,000+) compared to 1,200 or 2,100 with other batteries. So either they’re on the low-end of recharge cycles, or the company is just being modest and we’ll get better results. We’ll see; 1,000 cycles is a long time anyway.These look good and have worked well for me so far. I like the hard-plastic battery carry case, but if you latch it shut it’s difficult to pry open without a sharp edge.
