Have to say I was a tad apprehensive due to having really disappointing experiences with rechargeable batteries. They never seemed to give me the power required and lost their charge quickly. Thought I would give these a try and I am astounded just how good they are. Charged up in around an hour and give the same power as a conventional battery, and long lasting. I actually only needed 4 but so glad I ordered 12!! Thoroughly recommended 👍

This is the second lot of Paleblue batteries I've bought. They seem to be working fine, although I've only used them in the house heating thermostats so far, over the last three months or so. They charge up as quickly as claimed. I do have a couple of suggestions to make them more sustainable. Cardboard boxes rather than plastic would be great. I also now have more charging leads for them than I know what to do with! It would be much better if you had the choice to buy more batteries without charging leads.

So easy and just great. Won't be buying single use ever again

Excellent batteries well packaged pre charged and appear to hold charge well (not had long enough to test fully) Very pleased with the concept, well executed product looking and feeling far more premium than the multitude of alternatives available, reflected in the pricing. Bought on offer having previously purchased some 9v batteries which have been in use and not yet needed to be recharged.

Very innovative,having the charging slots on the battery.

Have not really used them as such, they are in a trail cam which I am still deciding where to site.

Packaging, presentation and shipping all first class. The only reason for 4 and not 5 stars is that as yet, I'm unable to test battery life.

Great investment, covered my costs in one weekend! Really the best way to use batteries if you need them.

These are easy to recharge and reuse. Very happy with them.

A great idea to be able to charge the individual batteries from a USB connector. Time will tell as to how long they last!

So far very impressed with my batteries, really like the led indicator light on each unit, charging seems pretty fast using the supplied USB A to C cables, time will tell if they live upto the advertising claims.I received one set of D size batteries that had a faulty charging cable but Amazon replaced these with their usual faultless return service.

Great must-do to reduce battery waste. It would be even better if in the future they could replace lithium with sodium

Amazing technology

During a consultation I frequently leave my Auroscope on discharging the batteries to flat. The LED Auroscope requires 3 volts , only possible with Alkalines or PALE BLUE batteries. I recommend PALE BLUE batteries to all clinicians

I love my paleblue home conversion kit, I'll never need to buy another battery again. They simply plug into my USB wall socket and within 90 minutes they're fully charged. I especially like the feeling that we'll never run out of batteries!

Really great start! Good batteries. Good recharge. Nice charging unit. Well designed. Want to see what longevity is like, but impressed so far!

Great product. Takes the hassle out of having to change batteries in every day products.

Good product, well packaged and easy to charge. Looking forward to seeing how they perform over time

These batteries are a little more expensive but they are the best I have ever seen. They are easily rechargeable with the chord plugging directly into each battery and then on a USB or C port. They charge up quickly and they keep their charge for a long time. I used the AA format in a battery operated tooth brush and the batteries lasted weeks. It is quite impressive.

Very well-made batteries. Included charger is very convenient.

Akkus sind in der Nutzung gut und halten vergleichbar mit einfachen Batterien. Kein Problem beim Aufladen. Etwas teuer.

I bought these little gems as I'm sick and tired of adding to the unnecessary resources required to service my needs.

Also customer services are awesome.
I had a question regarding charging requirements and I was told my batteries would get updated withiut having to throw them away.
Outstanding. First class product, first class customer service, first class company! 👍

it took few hours to fully charged. batteries are light.
great eco-friendly alternative to single use batteries.

I am very glad that I found your company, I have already bought several batteries. I like it very much! It is very convenient to use, easy to charge, no need for additional devices, so I recommend it to everyone and give it five stars.

Really convenient recharging. These batteries will not last anywhere near as long as even the cheapest non-rechargeable batteries but the advantage is that you can just plug them in for a couple of hours and put them back in your gadgets. In my tests I'd get about 2-3 days use from Pale Blue battery before needing to recharge where a conventional non rechargeable would last a week before I'd have to dispose of it.
