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, 4 Pack

Excellent. Charges fast, works reliably, and charges last a long time. Connectivity is easy, and the compact cord is so much more portable than the bigger plastic recharger units.

These are great.. recharge quickly.. instead of looking for where the batteries have gotten too.. or buying more and disposing of old.

I bought a pack of AAA and AA's from paleblue to test them out to see if they'd be a viable replacement for my devices. I've since replaced all the batteries in my everyday devices with paleblues. Wireless mice and keyboards, TV remotes, flashlights, Xbox Controllers, and so forth. They put out a true 1.5V from start to finish, which is both a good thing, aaaand a bad thing that's worth pointing out. A lot of battery life detection systems use the voltage to tell when the battery is low or dead. In a typical alkaline battery, the battery will start a little above 1.5V, and then drop down as it goes, so when the device detects about 1.2V or lower, it can tell the battery is drained and will notify you. These don't do that, they just die without warning. I can easily excuse that side effect with the longevity of these batteries, however. They last forever, and I can charge a pack of 4 in under an hour. I just keep a pack fully charged on shelf so if any die, I can quickly swap them out, just like I would with typical batteries, but now I don't have to keep buying the huge Costco packs to just throw them away. Save your wallet, and save the planet. Buy paleblue.

Good item with quick recharging. I use it for my game controllers and remotes and I am happy. One caveat, when these drop to a low enough voltage they simply stop outputting power so I would not use them for anything really critical

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 AAA 2. 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 own a business and personally use these batteries. They are the best thing in the world. They recharge in less than an hour. They run for days upon days months upon months. Depending on the application. In my mouth, it lasts two or three or four months. In something that has a higher demand it might last 30 days. So I buy backups and we just swap them out and charge them and have the others ready. They sit charged very well. We’ve had some that sat for 60 days and still had a full charge when we needed them.

Work amazing and easy to charge

These are by far the best rechargeable batteries I've ever owned! The design alone sets these above the rest - no need for a charging case or cradle, just plug the batteries themselves in with the included cable (which can charge all 4 simultaneously). Indicator lights on the batteries let you know when they're fully charged. Full charge appears to last as long as regular batteries. I've bought a few set of these to rotate out as other sets charge. I also like that they are USB-C. I can highly recommend these with no doubt!

As someone who's career has been working in office settings focused on records management and data entry, I quickly discovered that noise-cancelling headphones with hot-swappable batteries were a must for me. I had been using traditional rechargeables in my Bose Quiet Comfort 25's, and my recent experience had not been great, with the newest of those batteries only lasting for a little more than a day, and several of them no longer holding a charge at all. The Pale Blue Earth AAA batteries have a lifespan of around 3 of my 8-hour business days (24 hours total listening time), which is great for me. In the event that I did forget to charge them at home, the plastic travel case that holds the batteries also holds the charging cable nicely, and the batteries themselves only take about an hour to charge, so my noise-cancelling shields to save me from the constant chatter of the office environment would be back up relatively quickly. I had heard reports from people who were using these kinds of batteries in headphones where the electronics in the battery to control voltage had emitted a signal that then became audible in the headphones. In the several months that I've been using them, I have not detected this signal, however I have only been using them in the office environment where the drone of the air circulation system, and my chatty colleagues could be drowning this noise out. Beyond the longer life-span, the most drastic performance trait that I have noticed about these batteries is that when they die, they are dead. With the traditional rechargeables, my headphones would blink in and out of active noise cancelling as they died. I didn't particularly like that, so this new behaviour is something I'd mark as a plus. I'm also told that because the battery itself is tracking its lifespan, the light on the switch of the headphones won't indicate how much life is left in the batteries anymore. As the light is on the side of the headphones, and not in a place that I can see when I'm wearing it, losing this feature doesn't bother me. I imagine that as time progresses the lifespan of the batteries will take a dip, but my history with lithium ion batteries in all of the tech that I use on a regular basis is that these will probably have a much longer tail on them than traditional rechargeables.

Réception en temps et en heure (Prime) Produit rangé dans une petite boîte translucide de rangement assez pratique pour le voyage. Le câble USB livré avec est de très bonne qualité, les connecteurs sont en aluminium et très robuste. Les piles sont en 1.5 volt, ça change du 1.2v des piles rechargeables classiques. Elles délivrent la bonne tension pour les appareils électroniques. La recharge se fait facilement avec le voyant vert qui clignote sur le côté + de la pile. Qd elles sont chargées, le clignotant vert reste fixe. Côté autonomie, il y a mieux c'est certain, mais vu le prix, c'est plutôt bien placé. Très bien pour alimenter des télécommandes par exemple. Attention toutefois de ne pas les utiliser avec des appareils de puissance, elles risquent de surchauffer..... Elles ne sont pas faites pour ça. Stockage dans un endroit sec et tempéré. Lors du stockage, veillez à ce qu'elles ne soient pas chargées à 100% mais plutôt a 70% .

Çok fazla şarj edilebilir pil kullandım ama bunlar gerçekten harika...

充電器を使わず四股USBケーブル直結タイプで、付属のケースに電池とケーブルも収納できるので、携帯に便利です。

these batteries are very useful. even with a device that take two, the other two still hold a charge for use.
