In the time it takes to watch an episode of your favorite TV show, a Pale Blue battery is fully charged and ready to power your device. 2. Convenient USB-C charge port These batteries have an integrated safety circuit that protects both the battery and your device from common electrical issues such as overload, leakage, short circuit, over-voltage, and high temperature.

Almost all rechargeable AA and AAA batteries that we all have experience with are NiMh rechargeables. One of the problems with this chemistry for rechargeables is that it has high self discharge. This simply means that the charge goes down on its own when the battery is not in use. So, whether you charge them and put them in a drawer or into a device but don't use it, later when you go to use them, the battery will have less charge. Combine this with the voltage drop that you get when NiMh discharges to a certain level, and the battery suddenly performs poorly and for not as long as you'd expect. The power output of our product is consistently 40% stronger than an equivalent Alkaline and 50% more than a NiMh rechargeable. (Pale Blue holds stronger longer) Pale Blue are Lithium ion chemistry which has a much lower self discharge current and also holds a strong voltage through its discharge cycle.No. Lithium ion batteries have a very stable chemistry that will not leak like traditional alkaline or NiMh rechargeable batteries. I have also awarded them a Trail & Kale Editor’s Choice Award for their excellent design and performance. The LED indicator on Pale Blue batteries turns solid green when they are fully charged (the green light blinks while charging), providing a clear, visible sign that they are ready to use. The technology in these batteries is more advanced than the technology that has been used in previous generations of devices. Traditionally, rechargeable batteries have been powered by NiCd or NiMH power sources. These batteries will both lose significant power while in storage. NiMH batteries will also not provide as much power as NiCd or alkaline batteries, so high demand applications like radio controlled cars and drills may not be as fast or powerful. NiMH and NiCd also require about as many electrolytes as alkaline batteries so there is no room left in the battery for a charging circuit. This means that NiCd and NiMH will always have an external charging device. The LiPo chemistry that the Pale Blue batteries is based on has a very high discharge capacity, a very low resistance to charging and a very high energy density. This means that the Pale Blue batteries will stay charged for a longer time when not in use, can deliver a high amount of power while being used, and can be charged at a high rate. The high energy density means that the energy storage part of the battery can be smaller for the same capacity of energy typically stored in an alkaline battery and that there is still room for necessary circuitry and a charging port. In fact, LiPo can store approximately 350% more energy than a typical NiCd or NiMH battery. The batteries are tested (and have passed) IEC62133-2:2017 This is the international safety standard for all lithium batteries. It includes very extensive safety testing, a crush test and flame test. Pale Blue batteries are designed to pass all these tests safely with the external metal casing, which is stronger than many typical Lithium battery designs. No Lithium battery should ever be punctured with a metal object, such as a nail, this is the same for a mobile phone battery or power bank, or even a Tesla EV.

Overheat Protection: Operating at max output the battery will not overheat, this is part of the protection circuit. The included charging infrastructure is able to support a maximum of four batteries at one time. That’s actually pretty common, even older charging kits would usually let you power up four at a time. Another thing that you might want to keep in mind is that the USB connection is actually a Micro USB port, not a mini-USB port. A couple of years ago I was introduced to my first recharge-via-USB AA battery. The concept was novel, the execution was not particularly noteworthy as performance was not what I’d expect for in something trying to replace conventional alkaline. Also, NiMh batteries will discharge when not in use. So, if your headlamp hasn't been used in a couple months, you'll find your batteries will have lost a lot of charge over time. Pale Blue's Lithium ion chemistry and smart circuitry resolves all these issues.When the batteries are not being used they may be stored in the provided plastic container. The container is designed to hold 4 AA or 4 AAA and 1 AA. The picture above shows the way that each size battery fits into the case. Performance When measuring useful capability, we can look at the time for the battery performance to degrade to half of its starting power. The discharge time to get down to 50% of starting power is about the same for Pale Blue and Alkalines. So, in this respect, we are competitive with what you expect from Alkalines. a red LED indicates that the battery is charging and a green LED indicates that charging is complete. Compared to Duracell’s rechargeable NiMH AAA rechargeable batteries, though, Pale Blue Earth’s have a notable edge. Duracell’s rechargeable batteries advertise 900 mAh and 400 charge cycles. Energizer has its own version of these batteries also. They have 2,300 mAh, but only last several hundred charge cycles.

The Pale Blue also has an advantage that they are charged by a voltage regulating charging circuit. This means that charge time takes only a couple of hours and not the typical eight hours or more to charge a completely dead battery. The Pale Blue also has a circuit that protects the batteries from deep discharge – a condition in which the battery loses a significant portion of its charge holding capacity. Among other certifications, we are certified to IEC 62133:2012, the most important and relevant safety certification for Lithium Ion batteries. This standard specifies requirements and tests for the safe operation of portable sealed secondary cells and batteries (other than button) containing alkaline or other non-acid electrolyte, under intended use and reasonably foreseeable misuse. This is a major advancement from traditional rechargeable batteries, which are notorious for leaking when they’re drained or overcharged. These leaks can cause severe damage to electronic devices, sometimes beyond repair. Micro USB or USB-C Charge Port– Some models come with micro USB and others with USB-C. However, it looks like they are moving towards USB-C for all.

Design and features

Every battery you buy needs to be produced, shipped, stored, sold and disposed of. We believe this is a huge waste of the world's resources and creates unnecessary waste and carbon footprint. By using one Pale Blue, you can displace the need for 1000 batteries. This will save a lot of resources, and will also save you a lot of money over time.
