Review on 🔋 Panasonic Eneloop Pro Battery Storage Cases - 4AA or 5AAA Battery Capacity - Obsidian Gray (Pack of 2) by Adam Tidd

Cases work very well just what I wanted but the label is annoying because it's stuck on the front as I have several different brands of batteries. It would be better if they had a blue bottom and a transparent top - this would also allow for two different sides to be used to indicate "loaded" or "must load". I designed a battery storage system 15 years ago that used similar cases, but you could easily tell if the batteries needed charging or were fully charged based on the fact that you put them in the case (plus one way, to show the battery). . charged, and the other direction indicates the need to charge) or indicates the charging status of the whole body, with two sides of different color. I never commercialized it because I didn't want to get involved with hundreds of Chinese companies who immediately faked the design, but I wish someone had.
