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.

I bought different types of batteries, all charged full within few hours.
Great choice for kid toys, that require new batteries every few months.

Batteries seem to keep their charge very well and are easy to recharge just by plugging them onto a USB port with the cables provided. Well worth the purchase and good for the environment.

CR123A USB-C Rechargeable Batteries

AA & AAA Sustainability kit

I use batteries a lot with my camera and sound equipment accessories so I get through a lot of AA & AAA batteries. These are a great replacement that are quick and convenient to charge, and to use again and again! Would recommend.

Very prompt delivery - tracking facility - well packaged - good quality - can’t comment on performance until I’ve had ‘em a month or two but expecting it to be outstanding.

I got these for my electric guitar, which has a piezo bridge. I had previously tried conventional NiMh rechargables, but these tended to be over-sized and not fit properly in the battery compartment, meaning it did not close properly. I tried another cheap USB lithium rechargeable solution, but the voltage converter (I assume) introduced constant high-pitched noise that made it unusable for the guitar. I had almost given up, but found these. They are actually the correct size, and don't introduce noise! The piezo does not draw a lot of current so I have not ran the battery down to report on their capacity, but it has lasted a few months with no signs of stopping, and with everything else I am inclined to believe their claimed capacity. They cost more than other solutions, but it is worth it as the size and components are clearly better than competitors.

I bought these to use with guitar effects pedals, which in the past have not worked well with rechargeable 9v batteries, either because other batteries don't actually deliver enough power, or because they're not quite the standard size. These Paleblue ones work perfectly. They're the exact right size 9v is meant to be, and although I can't measure the power exactly, they are powering everything correctly. The time they last depends on the particular pedal I use them with, but even the most power-hungry pedals are lasting a couple of hours with them, which indicates the capacity is as much as Paleblue advertise. Recharge time has been quick, too. I'll certainly be buying more.

Makes perfect sense Very clever design.

Ordered 8 AA batteries as like many I despise single use batteries and normal rechargeable batteries do not even charge to the full 1.5v. I tested these and they did reach 1.5v. Been in use in keyboard and mouse for a couple of weeks and so far discharge rates are looking good.
They are also funky as heck!

Really good quality batteries including manufacturing quality.

I go through a 9v battery every 3 gigs so that equates to 1 battery every weekend. I have tried rechargeable batteries in the past that have not been up to the job. The Pale Blue 9v battery worked perfectly. As they come in a pack of 2 I can charge one whilst I use one saving me ££££s
