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 little setup for recharging batteries on the go. The 1 to 4 way adapter is slick and compact for traveling to not add weight and bulk. I got these for my older headlamp that doesn't take a rechargeable pack or have an internal battery and charge port. They are compatible with and function well in my old BD and Petzl headlamps. They are nice and light too. They are a great value from other more expensive rechargeable batteries. I got 2 packs so I can have a set in the headlamp and keep the spare to replace it with and charge up as to not be left in the dark

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!

I've bought several sets of AA & AAA batteries for the portable toys, remotes and small electronics. They quickly pay for themselves with recharge cycles. The LED indicators makes it easy to know their status when you plug in 4 at a time, using the 4 way USB splitter cable included. With two teenagers in the house, these have saved us a lot of money over throw aways.

I want to start off by saying I love the idea of rechargeable batteries, I especially wanted something like this for my peltors, and it’s SCU, but once I put batteries in both my ear defenders and it’s control unit and placing it on my hip, it kept cutting in and out unfortunately, I went back to just some basic rayovac triple A’s and the issue went away, so I’m not sure if it was just something with the batteries they both are 1.5v but for some reason normal alkaline batteries work better, either way i was disappointed and would just stick to alkaline for THIS specific situation, these batteries do seem good nonetheless I just wish they would have worked for me, oh well, I hope everyone else has good luck with them.

Pale Blue batteries provide full, 1.5 volts until depleted keeping devices bright and working correctly. Quick 2 hr. charge with provided USB charding cord makes recharging easy. Indicator lights show when the batteries are fully charged.

These are very reliable and last a long time. Our go to rechargeable batteries.

No more leaky alkaline batteries for me. Switching to Pale Blue, Lithium Ion USB Rechargeable battery equivalents are the best investment made. Sure, if purchase to replace all your alkaline battery needs at once you'd pay a tidy sum. However, if you buy 8-packs (pay less for) cells a little at a time, the first thing you know, you have enough Pale-Blues to power the most used devices. For me, it was a no-brainer. - Just do the math, how often do you have to replace batteries or, clean corroded battery holder terminals and cell springs? Also, Pale-Blues have more mAH capacity than any alkaline equivalent you're replacing. Pale-Blues have smart logic built into each cell. Near the end of its cell charge depletion, cell or series-parallel cell placements will have a slight dip in voltage, this provides the user with a subtle warning that you need to recharge your cell or cells, an example of this would be if using a flashlight, the LEDs would turn dim. - No problem, USB/Type C charge cable is included.

They don't last as long as regular batteries. But you do get a lot of charges out of them. So I'd say yes they're worth the money.
