paleblue USB Rechargeable AAA Lithium Batteries, 1 Hour Charge Time, Recharge Over 1000 Times, 600 mAh, 4-in-1 USB-A to USB-C Charging Cable, 12 Pack

Quick charging and easy to use

The best batteries ever made. They last longer than regular batteries. They are easy to recharge and they come with their own usb charging cable. Recharging takes only a few hours. Highly recommend them.

UPDATE! Pale Blue contacted me, and I have received their latest generation of battery with a lifetime warranty. The new batteries are the correct size for my flashlights and are correctly retaining their charge. I am updating my review to five stars.OK, I will be honest. I bought these in 2022. I think that Pale Blue has discontinued the Micro USB version.Now the problem I have had. The outer diameter of the battery is too large to fit my flashlights. Other brands of Lithium rechargeable batteries work just fine. So I use these in my blood pressure monitor. They lose charge in a couple of months. Even after a charge, the monitor says the voltage is low. Two different brands of monitors report the same problem. I've used alkaline batteries without this problem. So the big question? Has Pale Blue fixed this problem with the latest versions? To recap.1. Outer diameter is too large to fit in a space designed for for a standard AAA2. Charge retention time is substandard compared to their competion.3. Something is wrong with the amperage or voltage. Devices report the battery charge is low even after charging.Honestly, I rarely report a negative review. In this case it's warranted.

Bought these for remotes and electric door locks around the house. It's nice to be able to recharge batteries in low energy devices. Works as described and after a period of use I don't see a reduction of voltage output.

I am a commercial pilot and I use the AA rechargeable batteries in my Aviation headset and my headset is usually on for several hours out of the day and I’ve been averaging about 4 to 5 days before I need to recharge the batteries and they only take an hour and a half to recharge definitely saving myself quite a bit of money versus buying traditional batteries

I like these batteries. You can easily recharge them via usb

These batteries are awesome! Just as advertised! Will definitely be getting the AA package as well! I won't go back to disposable batteries ever!

I am using the batteries in a tap led light that takes 3 AAA's.First the batteries are NOT USB C rechargeable!! That's a USB C shaped port on the battery but if you connect it to a USB C charger, the battery will NOT CHARGE! You have to connect the battery to a USB A port. You can use a single USB A to USB C cable or their USB A to 4 USB C cables.Second I put 3 batteries that were drained until the tap light shut off onto their USB A to 4 USB C ports cable. The 3 batteries took a total of 829mAh to recharge the 3 batteries. (See attached photo of the meter) That's less than 300 mAh EACH! They are supposed to have a capacity of TWICE that!!Third the batteries have an extremely high self discharge rate! Simply put they don't hold a charge for very long! If I use alkaline batteries in my tap light, the batteries will last for MANY MONTHS of use! I put the Pale Blue AAA's in the tap light and even though I used the tap light just a few times for less than 2 minutes TOTAL, the batteries were going into their almost empty low power mode in less than 1 MONTH! I expected the batteries to hold a charge when not being used!Fourth is something I just noticed on the packaging while writing this review. Their math is clearly off or they are flat out lying! The packaging says 1 hour recharge time. The packaging also says 600mA capacity and a maximum input power of 200mA. Shouldn't it take 3 hours to charge the batteries? 200mA x 3 hours = 600mA? My batteries took almost 1.5 hours to recharge. 1.5 hours x 200mA = 300mA and considering the meter says 829mAh for recharging 3 batteries, this makes sense.If you want batteries that last, look elsewhere!!!
