What ever happened to newsreel?

They were on c cassette at 15/16IPS if I I remember correctly. And blind people would talk about different things.

The talking magazine called: newsreel used to sell them.  You might want to check at Walmart.

I don’t know how battery measuring instruments determine the percent of charge used but I wouldn’t consider the tongue method reliable.  It can tell you when a battery is so much depleted that the voltage produced isn’t near the amount intended, even after a period of disuse.  But Batteries often produce more current when they haven’t been used, and when used, the amount of current produced quickly goes down, perhaps significantly.  So the amount of current you feel on your tongue doesn’t necessarily tell you anything about the true state of the battery. 

 

I would hope instruments to determine the battery state are smart enough to determine the true state.

Melissa, for 9 volts, just use your tongue.  It works well and it is
very accessable.
