Automatic DIY polarity-independent AA battery charger (hackaday.io)
SPINC is an Open-Source NiMH charging station that can automatically load and eject AA battery cells. Simply drop batteries into the top of the device, regardless of their polarity. The internal mechanism picks up one cell at a time and fast-charges them sequentially. Up to 7 fully charged batteries can be conveniently stored inside the device for easy access. In addition, SPINC doubles as a desk clock, displaying the date and time on its high-resolution LCD.

Why Aren't There B Batteries? (2022) (thebatterygenie.com)
The “B” battery is a type of vacuum tube battery. It is used to provide constant and positive plate voltage and is colloquially referred to as a “dry battery.” The “B” battery was a high-voltage battery commonly used for antique tube radios. It was available in various sizes and shapes, with a voltage range of 45 to 90 volts. Unfortunately, B batteries are now scarce to find, as very few vendors still sell them in some African and European countries.
