Bob,

Some time ago you posted a simple circuit for doing an approximation of battery capacity. 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. I would like to build one of these to use as an annual battery condition test. 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'.
