Oldest cells?

I bought ten of these 4000mAh NiCd cells in 1984. Some of them still work. Here's one that is still in use - its internal resistance is a lot higher now so it'll only give 12amps or so when shorted these days -used to be about 50. It gives me about 4,200 measured mAh even 25 years on. The magnet thing it is hanging from is very handy for charging stuff. I own quite a few of them.

 

I think Photobucket is having a bad day. The image show hideous artefacts and wasn't nearly that bad originally - wonder if they've archived it and have dredged up a thumbnail. It took an inordinately long time to display.

 

The numbers from my light tests are always to be found here.

It looks as if the pic was smaller and resized to fit the screen......kind of blurry.

With Darkness, there will always be Light.
