Using a Battery Tester using the meter and the case
I got a Battery Tester from Cousins. Costs just under £10, has a meter, switch and case. I thought that this be a good starting point, but it was found that this unit was too small to use in the end. A larger box and meter was used in the final version.
The switch is unsuitable.
The circuit of the tester follows:-

The parts that I thought would be used are the
Meter
Lead with Probes
Size of PCB 45 x 55 mm - strip-board replacement.
Case
All other parts are removed. There is sufficient depth for mounting switches along the side.
Second Results
This section highlights the changes that were made to the original design, including what happened when it was discovered that the PCB would not fit into the meter box when built.
