From the project
This project aims to make a PCB and case to easily use a standard 6V lead-acid battery with spade connector as the Macintosh Portable battery.
This project was created to allow current rectangular 6v lead-acid batteries with spade terminals to be used as a Macintosh Portable battery in a cost effective manner. This is achieved with a spacer made of plastic or cardboard and PCB for the battery contacts. The lead-acid battery is then connected to the PCB via wires with female spade connectors.
The spacer and PCB is sufficient and the cheapest way to use a 6V lead-acid battery in the portable. This is useful for testing since the battery can be easily swapped.
