voltage testing "dead" batteries
Authored by: sjk on Dec 24, '08 10:47:38AM

I highly recommend voltage testing disposable batteries before getting rid of them. An inexpensive digital multimeter works well for that purpose.

When my Bluetooth keyboard runs low on power usually at least one of the four original batteries still has nearly a full charge. I'll check if NiMH rechargables will work okay in that keyboard as soon as the current batch of alkalines I've reused runs out. I was getting about a month from 'em in a non-Mighty Bluetooth mouse before switching to a wired Mighty mouse (whose scroll pea hasn't worked for over a year, sigh, and stopped responding to any external methods of cleaning that had previously temporarily helped).
