[Ham-Computers] Computer Clock Problems (Herb Gerhardt)

[Philip (KO6BB)]

To create a 'load', you need nothing more than a simple half Watt 
resistor of appropriate value.  Use Ohms Law to calculate the value for 
whatever battery Voltage you're testing (probably 3.2 Volts for the 
buttons).  I would suspect that just a couple mA or so would be needed 
to simulate a realistic load.  Put the resistor in parallel with the 
meter you're using to test the battery.

As a side note.  I have a "clip-on" guitar tuner that eats the 2032 
cells like they were candy.  Besides the LCD "meter", it lights 
red/green/amber to indicate if you're tuned dead on, sharp or flat.  I'm 
sure it's that lamp that eats the batteries as I have another clip-on 
tuner that uses a very tiny CR1220 cell that lasts months (but doesn't 
light up on a dark stage).
