Battery tester
I have many battery testers--all of them handheld and fairly delicate. I wanted something I could use in my workshop that would take the normal wear and tear of my goings-on without failing. In other words, I wanted a "beater," something that I wouldn't cry over if it were damaged or broken.
I found it with this 1950s Burgess Battery tester. It would have been installed over a point-of-purchase battery display. Customers would be able to test any LT or HT battery up to 90 volts and determine if they needed a replacement. All I had was the tester and its mounting panel, so I cobbled up this shelf over the weekend. Nothing special in its design, just something that would hold the battery while I went over its voltages. I made it large enough to hold a Zenith Trans Oceanic battery. I replaced the broken test leads with longer ones so I would be able to test a larger batteries on the test bench. The frame was made with long garden stakes, (think miniature 2x4's) the outer skin is MDF. Four coats of red and white enamel were applied. The finish is fuzzy, pretty rough--but this thing's going to see rough service out in the garage, so I'm not terribly particular about its beauty. I also made a cell tester pad out of a piece of circuit board material and an alligator clip. It allows you to test cells without needing three hands--one to hold the cell, one to hold the negative and one to hold the positive... Function is simple: the negative lead is joined to the clip, and then any D-, C- or AA-battery is installed on the pad. The nice thing about this small tester bench is that it's light enough to be hung on the wall, and it's exactly where this one's going.

Re: Battery tester
Does it test the batteries under load?

Re: Battery tester
Sure does.
And I built it to help in building batteries for a certain client you and I know.

Re: Battery tester
That's just super, looks really good and every bit as functional and useful! You're a very clever man Bill, well done!

Re: Battery tester
Thanks all for the compliments.
And here's the tester nestled in its place on the wall...pardon the mess, it's far worse than what you see here....

Re: Battery tester
Hello
Just spotted this. Are you shure that tester isn't too pessimistic? -- it looks to have been made for shops selling new batteries after all ;-) Bye William |

Re: Battery tester
Fortunately the scale doesn't read from BAD to MUCH WORSE....

Re: Battery tester
Really excellent job sir. "Neat" in both the English and US sense. You are turning out items of museum display quality there. I won't be going that far but I do keep meaning to make a simple jig for multiple testing of smaller rounder cells as balancing them between the points of test leads gets a bit tedious.

Re: Battery tester
Thanks much for the compliments. Wouldn't call it museum quality if you saw it up close, but then again it's for go, not for show....
Not much needed for an adaptor. A block of wood, circuit board material, a wire with an alligator clip's pretty much all that's needed. Amazing how handy something simple can be. Never thought much about it until I had a D cell land on my foot while attempting to test it...
