usb-c batteries

This tag covers discussion of USB-C rechargeable AA batteries, particularly as a practical upgrade for wireless mice and keyboards. The tagged content focuses on lithium-ion cells with built-in USB-C charging ports, which let you keep existing peripherals instead of replacing them or modifying hardware. It highlights what to check before switching, such as whether the charging port sits on the battery itself rather than the device, and the value of keeping spare charged cells on hand. The emphasis is on battery management and convenience for everyday desktop accessories rather than a hardware conversion, making it relevant to Windows users maintaining wireless input devices.
