Actually many smoke detectors have two 9 volt batteries one for the
detector and one for the light. Since the light is rarely used the
battery is basically new. Most people replace both batteries. I
volunteer at a recycling center, we take household batteries, I have a
little handheld tester and when things are slow I test the "donated"
batteries. I have several shoe boxes full of batteries. I give the
scouts some of the batteries, they camp every month all year. We had a
donation last month of 4 cases of batteries that were date expired 2
months ago, new never opened, they still work great.
It's amazing what is discarded.
One side affect of recycling in a small town is everyone knows I also
recycle/collect computers. They appear on my door step or are dropped
off at the monthly recycling. One of my neighbors called up and offered
me 2 PDP-11/70's and a VAX 11/785 from an engineering film. My wife was
not very happy about the space they filled in the garage.
