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.
