		  Bob,

  

 Some time ago you posted a simple circuit for doing an approximation of battery capacity.Â  The circuit consisted of an analog electric clock to measure the time required to discharge a battery, through a light bulb, down to 10 volts.Â  I would like to build one of these to use as an annual battery condition test.Â  Can you direct me to where I might find information on how to make one? 	


   Yeah . . . that was a pretty crude, first

   pass at a po' boy's cap checker. That

   article can be found here:

   There's a more accurate and convenient version of

   that project in the works but the device

   in the article will produce good benchmark

   numbers for your battery's 'stage of service

   life'.
