Open replacement battery module for the Compaq Portable III using a CR2477N coin cell.

This is a self-assembly project rather than a retail product. Follow the documented cell polarity and solder the pin headers in the specified upside-down orientation.

Provides a portable 128 KB enhanced Apple IIe-compatible system with an integrated LCD, speaker, and microSD-based floppy and hard-disk images.

On 2026-07-27, the 3.2-inch page exposed case choices and an Add to cart control, although another stock marker on the same page said out of stock. The 1.6-inch and built-in-keyboard models were explicitly out of stock. Check the selected variant before ordering. A microSD card and USB power supply are not included. The 1.6-inch model also needs a separately sourced lithium battery and soldering work; its battery must be charged with the emulator switch in the OFF position.

Adapts a CR2032 coin cell to a vintage Macintosh 1/2-AA battery socket.

The current storefront listed single and three-pack configurations on 2026-07-24. The optional vertical bracket is sold separately.
