Google ELK and battery tester. Elk makes one that measures the internal
conductance of the battery in mhoes. My company uses them to test customer's
batteries with good results (alarm company).

I'm wondering if there's a simple or straightforward way to test an SLA
battery for general condition. Or a device I can buy that sucks a
charge out of a battery over a few hours and reports its actual
amp-hour capacity?
