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, 8 Pack

Great Batteries, recharges faster than my old Ni-Cad's. Love the Light indicators at the top of the batteries so no guesswork to when they are done charging. Small carrying case fits in your pocket.

These are the only rechargeable AA and AAA batteries I've run across that actually provide 1.5 volts. Their total amp hours are lower than a disposable but since they charge quickly you simply buy a spare set and keep it charged. Being able to charge four at a time with the included USB-A to USB-C connector is a serious improvement over having to carry around a bulky battery charger.One word of warning - devices that warn you of depleted batteries generally do so by monitoring the drop in amperage delivered. Lithium Ion batteries, include Pale Blue batteries, don't have a gradual drop off in amperage. They run until their exhausted so there's no warning the battery is nearing depletion. Therefore, these aren't recommended for door bells, fire alarms, etc. However they work perfectly in everything else.

I recommend this item to anyone who wants a rechargeable battery. They are extremely easy to charge just connect them to any wall usb wall charger and bam the batteries are charging, no extra equipment just the batteries and the cable. They also keep the charge for a very long time. Since I bought them I’ve only charged them the day they’ve arrived. I have tried them on two different products remote control for the tv and also my smart scale which uses 3 triple aaa. 5/5 starts for everything.

They have long lasting battery life and very unique design, I love these things and the fact they charge with usb-c let's you charge multiple at the same time! Eventually want to get me more of their other types.

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.

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 have purchased AA, AAA, and 9 Volt Pale Blue batteries for several years. I have never had any issues at all with their batteries and thus they are the only manufacturer that I buy on my quest to replace all disposable batteries in my electronics. I love the way they last so long between charges. The USB-C port makes them so simple to plug in and charge. The bright color status light makes it easy to see when they are full. Outstanding quality and brilliant design. Pale Blue for the win!

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.
