ABSTRACT:
A device for rapidly testing a battery includes a conditioning resistor and a depressible momentary type switch interposed in series between the conditioning resistor and the battery terminals, such that the closing of the switch allows current flow through the conditioning resistor in approximately the full amount the battery can generate when fully charged. In parallel with the conditioning resistor are a number of sets of voltage dividers and comparators working in conjunction with each other to compare a divided down battery voltage with a fixed voltage reference. Each comparator has an associated indicator light such that all the indicator lights will light up if the battery is at full capacity, but less than all the indicator lights will light up if the battery is at less than full capacity.
