Ever wonder why one brand of battery works in an electronic lock while another brand new battery doesn't?
The E-Lock Battery Analyzer will give you that answer in seconds. Instead of simply measuring battery voltage like a standard voltmeter, the Analyzer actually measures battery performance. Just plug in a 9-volt battery and hit the button on the tester to get an instant analysis of a battery's overall condition and performance. You'll find that many expensive brand name batteries fail the test even when brand new while some cheaper batteries pass with flying colors.
The E-Lock Battery Analyzer will tell you immediately if a particular battery will perform properly in today's modern electronic locks.
