Test : Pale blue Li-Ion Batteries
Background Batteries can be expansive and environmentally unfriendly. Of course, alternatives exist but none of them are truly satisfying. Rechargeable batteries are not providing more than 1.2V, they do not last long and require frequent charge cycles. While scrolling my Facebook feed, I found an interesting ad about a company called Pale blue providing Lithium Ion batteries with the standard batteries form factor with 1.5 V and a standard micro USB port to charge them. Is this the Grail ?
